python--string

Python does not support single character types, and one character is also used as a string in Python.

str = "Hello jiao"; # before starting from index 0 to Index=-1 (contains index=0 does not contain index=-1 "index=-1 is the last character of the string") print (str[0:-1]); Hello jia# starting from index 0 to index=4 (contains index=0 does not contain index=4) print (Str[0:4]);p rint (str[: 4]); # hell# Starting from index 6 to end (contains index=6) print (str[6:]); # jiao# output two string print (str * 2); # string concatenation print (Str[0:5] + "world!!!"); 

The string hollow lattice is not omitted.

Escape character Valid

The string method will only return the modified string, the original string variable will not be changed (that is, you cannot modify a character in the string, error)
