Python string explanation

Python has five data types, namely: You can view data types using the type built-in function

1:str (String) 2:int (integer) 3:float (floating-point)

3:list (list) 4:dict (dictionary) 5:set (collection)

STR (string) is an immutable type: Each variable corresponds to the value of the data and variable names in the memory is actually associated with, when the value of B is actually opened in memory in a new space, the B point to the new space, and did not directly change the data of the memory space that the B originally pointed to:

Python has a number of methods built into each data type, and the flexibility to use these methods can reduce our code volume a lot, so I'll show you some common methods for strings:

Str.replace ()//String substitution

Str.strip ('/')//clear closure of specified symbols

Str.split ()//String segmentation

Str.endswith//Judging the end of a string

Str.startswith () //Judge string start

650) this.width=650; "src=" Https://s3.51cto.com/wyfs02/M01/8E/DE/wKioL1jOACbzPzXoAAAUKUNNq-k934.png "title=" 7.png "Width=" "height=" 98 "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:500px;height:98px; "alt=" Wkiol1joacbzpzxoaaaukunnq-k934.png "/>

Str.lower ()//change string to lowercase

str.upper () //change string to uppercase 650) this.width=650; "Src=" Https://s3.51cto.com/wyfs02/M01/8E /e0/wkiom1jn_wzqrsrgaaak_sg1w_s395.png "title=" 4.png "style=" FLOAT:LEFT;WIDTH:500PX;HEIGHT:86PX; "width=" 500 " height= "border=" 0 "hspace=" 0 "vspace=" 0 "alt=" wkiom1jn_wzqrsrgaaak_sg1w_s395.png "/>

' Specify stitching symbol '. Join (str)//string concatenation

String slices:

string concatenation:

There are many built-in methods for strings, but these are common, and I hope you will be helpful to your friends.
