海外TECH	DEV Community	Basics of Python "String"	https://dev.to/mouly22/basics-of-python-string-44kg	Basics of Python quot String quot String String is a sequence of ordered characters alphabets lower case upper case numeric values special symbols Strings are either enclosed with single qutation marks double quotation marks Also we can write multi line string using triple qutations both The character order is always from left to right print Hello I am mouly print Helloo I am Mouly print This isa multi line string and wecall it Doc Strings Output Hello I am moulyHelloo I am MoulyThis isa multi line string and wecall it Doc Strings we can use either single quotation or double quotation as long as we are consistant about which qutation we are usingprint He was in the dead sea while listening Ocean Eyes Output He was in the dead sea while listening Ocean Eyes This qutation sequence can easily be maintained by using preceding backslash which is called as an escape character print I manage because I have to Because I ve no other way out print Don t you know How can you ignore Output I manage because I have to Because I ve no other way outDon t you know How can you ignore An empty string also holds an indexing positionprint empty stringprint Output Typethis built in fuction returns the type of an objectname alan walker print type name type of name variableOutput lt class str gt Also p this is a stringq this is an integerprint type p print type q Output lt class str gt lt class int gt Even though p and q might look same to you their types are different and there are different consequences for this p q print p print q Output butp q print p this will give an errorprint q Output TypeError can only concatenate str not int to strHere p is a string Even though happens to look like a number in python it s just a sequence of characters and we can t add a number to a sequence of characters we can add them if we cast this p string into an integer p q print int p this won t give an errorprint q Output p print p string concetenationOutput When we call a int of float to cast a string it needs to be a valid number p taka print p Output TypeError can only concatenate str not int to strSo python can t convert this string into integer Strings are sequential collection datatype This means a string is actually a collection of single characters IndexingWe can access an individual character of a string or part of a string using the indexing operator For accessing individual character by it s position or index value This index value always begins at zeroIndexing can be done in two ways Positive Indexing is used to access characters from the left side of a string and it always starts from and ends at the last character of the string Negative Indexing is used to access characters from the right side of a string and it starts from and ends at the first character of the string REMEMBER A string with six characters have entities from through So if we want to access a th character of a string we ll use an index of The basic string indexing structurestring name index value xmple we want to access print xmple print xmple print xmple positive indexingprint xmple negative indexingprint xmple index out of rangeprint xmple type errorOutput wtsIndexErrorTypeErrorthe built in function len helps us determine the length of a string So the last index of a stirng will always be one less than the length of that string len string xmple we want to access print len xmple length of a stringOutput If we want to access last character of a string we can do either of them from below xmple we want to access print xmple len xmple print xmple Output eeSlicingSlicing is used for getting a substring of a particular string This allows us to create a sub string that is more than one character long Colon is used as a slicing operator Keep in mind that the slice operator leaves the original operator intact Basic structure of slicingstring name beginning end step size beginning The index where slicing starts inclusive If not provided by default starts from index end The index where slicing stops Not inclusive If not provided by default includes the rest of the string after “beginning step increment of the index value If not provided by default the value is xmple we want to access print xmple Output e want tIn this example the colon used in this slicing operator will return the characters from index upto index so not including index and the increment will be String Operators Concatenation We can concatenate strings by using the plus sign var we want var to visit a var zoo var var var var concetenation of a stringprint var Output we want to visit a zooNotice one thing this sign doesn t add any space while concatenating Repetition We can create a new string with the specified number of copies of the input string using this method v repeattime print v Output repeattimerepeattimerepeattimerepeattimeBuilt in methodsIt s important to remember that Python is IMMUTABLE Immutable means once it has been created its value cannot be changed So each time we have to modify the values we need to make a copy of the original one and make changes to the duplicate one me Abira me e Output TypeError str object does not support item assignmentPython has some built in method to access or process characters in string For example count substring methodwe can use the count method to count the occurances of a particular substring place I want to visit USA print place count i Output As python is case sensitive we can t access I here cause the ASCII value of I is different than i index substring methodwe can use the index method to find the index of the first occurance of a given substring place I want to visit USA print place index i Output Upper and lower methodUpper returns the copy of a given string in all uppercase letters while lower returns the copy of a given string in all lowercase letters place I want to visit USA print place upper print place lower Output I WANT TO VISIT USAi want to visit usaupper or lower method takes no arguments strip methodthis strip method returns the copy of a string by removing the whitespaces from before and after letters Whitespaces refers to any character that represents a space in text like a tab a space or a new line character new Well this is another line Strips all whitespace characters from both ends print new strip Output Well this is another line Notice the whitespace between characters are not removed only the before and after letters whitespaces are removed replace oldstring newstring methodthe replace method replace every instance of oldstring with newstring in a string exm wd ard hdrd nexm exm replace d e print nexm Output we are here split methodSplit helps us breaking sentences of a string into more managable pieces Split takes a delimiter and splits the string into sub strings The method returns a list where each item is a sub string that is cut at every instance of that delimeter For example song Tell me why Aint noting but a heartache Tell me why Aint noting but a mistake print song split Output Tell me why Aint noting but a heartache Tell me why Aint noting but a mistake This output comes as a listHere is the delimeter so It will cut in those places and won t return the delimeter in output x Library is a place where you can find peace print x split Output Library is a place where you can find peace Here my delimeter is a space So the resulting list will include every word in that sentence but no spaces x Library is a place where you can find peace print x split a Output Libr ry is pl ce where you c n find pe ce So the split method won t include the delimeter in the list it returns join methodThe inverse of the split method is join We can choose a desired separator string often called the glue and join the list with the glue between each of the elements x light blue sky it s raining hard colin where you go y p y join x print p Output light blue sky it s raining hard colin where you go We can also use empty string or multi character strings as glue	2022-01-09 12:02:17
