海外TECH	DEV Community	A Practical Guide to Metaprogramming in Python	https://dev.to/karishmashukla/a-practical-guide-to-metaprogramming-in-python-691	A Practical Guide to Metaprogramming in Python What is metaprogramming Metaprogramming is a programming technique where a program can modify or generate code at runtime It allows developers to write code that can analyze modify or create other code In other words metaprogramming is a way of writing programs that manipulate programs Metaprogramming is supported in a lot languages including Python JavaScript Ruby Clojure Julia and Java even though it is considered to be very static and verbose language img alt Relationship between structural and process concepts of metaprogramming lt br gt height src dev to uploads s amazonaws com uploads articles oicklbmvhukvn png width Fig Relationship between structural and process concepts of metaprogramming Image from Research Gate Where is metaprogramming used Metaprogramming is useful for a lot of use cases Some of them includeFrameworks and LibrariesCode GenerationTemplate Engines Metaprogramming in PythonMetaprogramming in Python allows you to write code that can manipulate code itself creating new code modifying existing code or analyzing code structures Python provides several mechanisms for metaprogramming Let s explore each of them with code examples DecoratorsDecorators are functions that modify the behavior of other functions or classes They wrap the target function or class and provide additional functionality Decorators use the symbol and can be applied to functions or classes Here s an example def uppercase decorator func def wrapper args kwargs result func args kwargs return result upper return wrapper uppercase decoratordef greet name return f Hello name print greet Karishma OutputHELLO KARISHMA In the above example the uppercase decorator modifies the behavior of the greet function by converting its return value to uppercase MetaclassesMetaclasses allow you to define the behavior of classes They act as the blueprint for creating classes and can modify class creation and behavior Here s an example class MetaClass type def new cls name bases attrs uppercase attrs key upper value for key value in attrs items if not key startswith return super new cls name bases uppercase attrs class MyClass metaclass MetaClass message Hello World print MyClass MESSAGE OutputHello World In the above example the MetaClass metaclass modifies the attributes of the MyClass class by converting them to uppercase Function and Class DecoratorsBesides using decorators with the symbol you can also apply decorators using the function or class syntax Here s an example class CubeCalculator def init self function self function function def call self args kwargs before function result self function args kwargs after function return result adding class decorator to the function CubeCalculatordef get cube n print Input number n return n n nprint Square of number get cube OutputInput number Square of number In the above example we define a class decorator CubeCalculator that wraps the function get cube to perform additional actions before and after its execution and then applies the decorator to the get cube function When get cube is called with an input number it prints the input number calculates its cube and returns the result Dynamic Code GenerationPython allows you to generate code dynamically using techniques such as eval or exec This can be useful for generating code based on certain conditions or dynamically creating functions or classes Here s an example name Karishma age code f def greet n print Name name n print Age age exec code greet In the above example the code string is dynamically generated and executed using exec to define the greet function Most common in built keywords and functions for metaprogramming in PythonIn Python the following keywords and concepts are commonly associated with metaprogramming and provide the foundation for metaprogramming getattr dir hasattr These functions allow you to dynamically get and set attributes of an object at runtime The built in inspect module is responsible for an important concept of metaprogramming called introspection in which the program simply looks at and reports on itself exec eval and compile These functions enable the execution of dynamically generated code strings or evaluation of expressions getattr and setattr These special methods can be defined in classes to handle attribute access and assignment dynamically metaclass This special attribute can be used in a class definition to specify a metaclass for that class ConclusionThese are some of the ways to achieve metaprogramming in Python Each technique provides flexibility in manipulating code structures and behavior enabling you to create more dynamic and flexible applications If you like what you read consider subscribing to my newsletter Find me on GitHub Twitter	2023-07-16 18:25:22
海外TECH	DEV Community	Are you a T-Shaped Developer?	https://dev.to/aellon/are-you-a-t-shaped-developer-4npk	Are you a T Shaped Developer I never put much thought into what type of developer I am until now but the other day a colleague mentioned that all of the engineers on our team should work toward becoming T shaped developers I knew there are frontend backend and full stack developers but what in the world is a T shaped developer After a bit of research I learned that a T shaped developer embodies the best of both worlds between being a specialist and a jack of all trades They are an experienced expert in one field with some knowledge in other areas too While full stack usually entails that knowledge is generalized across the board a T shaped developer is a shiny rebranded version of full stack It has the well roundedness of full stack with the added bonus of a specialized area of expertise In the following chart example the teal background color shows my depth of knowledge in data integrations the vertical part of the T as well as breadth across frontend backend full stack and mobile app development the horizontal part of the T I omitted some skills from the teal area for the sake of making a perfect T shape so a truer representation of my skills would look more like an abstract shape scribbled by a toddler There s no clear cut definition of which fields are included as part of the chart and the shape s contents seem to be entirely customizable We all know that being a software engineer encompasses more than just writing code all day so the next example shows my skills in the software engineer column along with aspects of other roles that I take on regularly You see the chart can look different for everyone Our levels of expertise are subjective and relative so I could argue that every developer is already a T shaped developer Creating a personal chart is a great exercise to dive deep into your own levels of expertise What do you think are you a T shaped developer	2023-07-16 18:08:16
