海外TECH	DEV Community	How to Use exec() in Python - Everything You Need to Know	https://dev.to/sachingeek/how-to-use-exec-in-python-everything-you-need-to-know-380f	How to Use exec in Python Everything You Need to KnowThe exec function in Python allows us to execute the block of Python code from a string This built in function in Python can come in handy when we need to run the dynamically generated Python code but it is recommended not to use it carelessly due to some security risks that come with it In this tutorial we ll be going to learnhow to work with Python s exec functionhow to execute Python code using the exec function with code examplesexecuting Python code from a string and Python source fileusing globals and locals parameters Python s exec functionPython s exec function allows us to execute any piece of Python code no matter how big or small that code is This function helps us to execute the dynamically generated code Think of a Python interpreter that takes the piece of code processes it internally and executes it the exec function does the same It is like an independent Python interpreter The exec is capable of executing simple Python programs as well as fully featured Python programs It can execute function calls and definitions class definitions and instantiations imports and much more Syntaxexec object globals locals object It must be a string or a code object If it is a string it is parsed as a suite of Python statements which is executed unless a syntax error occurs If it is a code object then it will simply execute globals and locals This allows us to provide dictionaries representing the global and local namespaces Return valueThe return value of the exec function is None It may be because every piece of code doesn t have the final result Initial glanceHere s an initial look at the working of the exec function obj apple cherry melon strawberry code print sliced for sliced in obj if a not in sliced exec code cher melo Another example of using the exec function The code will continuously run and we can run our code as we do in Python interpreter while True exec input gt gt gt gt gt gt print Welcome to GeekPython Welcome to GeekPython gt gt gt import numpy as np gt gt gt print np random randint size gt gt gt x apple banana cherry mango gt gt gt print fruit for fruit in x if a not in fruit cherry It works exactly like a Python interpreter taking our code processing it internally executing it and returning the correct results We re running an infinite loop and inside it we re taking input from the command line and wrapping it in the exec function to execute it Executing code from a string inputWe can use the exec function to execute the code which is in a string format There are multiple ways that we can use to build the string based input Using one liners codeUsing new line charactersUsing triple quoted strings with proper formatting Using one liner string based inputIn Python single line code also known as one liner code is code written in a single line that can perform multiple tasks at the same time If we wrote a single line of Python code it would look like this obj apple cherry melon strawberry print sliced for sliced in obj if a not in sliced Output cher melo But if we run the above code using the exec the code would beobj apple cherry melon strawberry exec print sliced for sliced in obj if a not in sliced OR exec code sliced for sliced in obj if a not in sliced The other code we wrote above will return nothing if we execute it instead the output will be stored in the code variable for later access Executing multiple lines of code separated by new line charactersWe can combine multiple statements in a single line string using the new line characters n exec square int input Enter the number nprint f The square of square square OutputEnter the number The square of A new line character n is defined to make the exec function understand our single line string based code as a multiline set of Python statements Using triple quoted stringIn Python we frequently use triple quotes to comment on or document our code However in this case we ll use it to generate string based input that looks and behaves exactly like normal Python code The code we write within triple quotes must be properly indented and formatted just like normal Python code See the example below for a better understanding sample code integers def square num return num def odd num num return num square if even square number for number in integers if number odd number number for number in integers if odd num number print Original values integers print Square of even number square if even print Odd number odd number exec sample code OutputOriginal values Square of even number Odd number The above code is similar to standard Python code with proper indentation and formatting but it is wrapped within triple quotes resulting in string based input stored in the sample code variable which was then executed using the exec function Executing code from a Python fileWe can use the exec function to execute the code from Python py source file by reading the content of the file using the open function Consider the following example which includes a sample py file containing the following code sample pydef anime name print f Favourite anime name anime One Piece list of anime input Enter your favourite anime split print Your Favourite anime list of anime The code simply prints the anime s name here while the following block of code takes the input of your favorite anime separated by commas and prints the desired output Executing the Python source file using the exec functionwith open sample py mode r as sample file sample read exec file OutputFavourite anime One PieceEnter your favourite anime One Piece Naruto Demon Slayer Jujutsu kaisenYour Favourite anime One Piece Naruto Demon Slayer Jujutsu kaisen We used the open function using the with statement to open the py file as a regular text file and then used the read on the file object to read the content of the file as a string into the file variable which is passed in the exec to execute the code Using globals and locals paramsThese parameters are entirely optional We can use globals and locals parameters to limit the use of functions methods and variables that aren t required Because these parameters are optional omitting them causes the exec function to execute the input code in the current scope Consider the following example to better understand it code out str strprint out global variablesstr Hel str lo exec code OutputHelloThe code above ran successfully and produced an output that combined both global variables Because the globals and locals parameters were not specified the exec function executed the code input in the current scope The current scope is global in this case Here s an example of how to get the value of a variable in the current scope of code code out str strprint out global variablesstr Hel str lo print out Traceback most recent call last NameError name out is not defined Did you mean oct In the preceding code we attempted to access the value of the out variable before calling exec and received an error However we can access the value of the out variable after calling exec because the variable defined in the code input will be available in the current scope after calling exec exec code print out OutputHelloHelloUsing globals and locals parameterscode out str strprint out global variablesstr Hel str lo exec code str str OutputTraceback most recent call last NameError name str is not defined Did you mean str The code returns an error because we didn t define the key holding the str in the dictionary so the exec doesn t have access to it code out str strprint out global variablesstr Hel str lo exec code str str str str print out OutputHelloTraceback most recent call last NameError name out is not defined Did you mean oct The exec function now has access to both global variables and the code returns the output without error but we didn t have access to the out after the call to exec this time because we re using the custom dictionary to provide an execution scope to the exec Here s an example of using locals and globals togethercode out str str xprint out global variablesstr Hel str lo def local local variable x there exec code str str str str x x local OutputHello thereIn the above code we called exec from within the local function In the global scope we have global variables and a local variable in the local scope function level The globals parameter specifies the variables str and str while the locals parameter specifies the variable x Blocking unnecessary methods and variablesUsing the globals and locals params we can control whether to restrict or use any variable or method in our code input In this section we ll limit some of the functions in Python s datetime module from datetime import code curr time datetime now print curr time exec code OutputTraceback most recent call last NameError name datetime is not definedWe restricted the use of the datetime method from the datetime module which resulted in an error Using necessary methods and variablesWe can only use the methods that are required with the exec from datetime import Allowing only two methodsallowed param datetime datetime timedelta timedelta exec print datetime now allowed param exec print datetime now timedelta days allowed param date method is not allowedexec print date allowed param Output Traceback most recent call last NameError name date is not definedThe error occurred because the date method was not permitted Except for two methods datetime and timedelta all methods in the datetime module were forbidden Let s see what else we can accomplish with globals and locals parameters from datetime import Setting globals parameter to builtins globals param builtins builtins Setting locals parameter to take only print slice and dir locals param print print dir dir slice slice exec print slice globals param locals param exec print dir globals param locals param Outputslice None None dir print slice Inside the exec function only the slice method and all built in methods can be executed Even though the slice method is not from the datetime module it works perfectly here We can also limit the use of builtins by setting it to None from datetime import Setting globals parameter to noneglobals param builtins None Setting locals parameter to take only print slice sum and dir locals param print print dir dir slice slice sum sum Allowed methods directoryexec print dir globals param locals param exec print f Sum of numbers sum globals param locals param Output dir print slice sum Sum of numbers We limited the use of builtins so we can t use the built in methods and can only execute the print sum slice and dir methods inside the exec ConclusionWe ve learned how to use the built in Python exec function to execute code from a string based input It allows you to run dynamically generated Python code The topics we ve learnedwhat is exec function and working with itexecuting Python code from a string based input and Python source filesunderstanding the use of the globals and locals parametersAdditionally we ve coded some of the examples which helped us understand the exec function better Other articles you
