*Memos:
- My post explains a string.
strip() can remove zero or more characters(chars) from the left and right character of a string one by one as shown below:
*Memos:
- The 1st argument is
chars(Optional-Defualt:None-Type:strorNoneType): *Memos:- It's the zero or more characters to remove from the left and right character of a string one by one.
- Its each character is considered one by one so it's not a prefix and suffix.
- If it's not set or
None," "is set. - Don't use
chars=.
v = " aa bb cc " # ↑↑ ↑↑ print('"' + v.strip() + '"') print('"' + v.strip(" ") + '"') print('"' + v.strip(" ABC ") + '"') # "aa bb cc" print('"' + v.strip("a ") + '"') print('"' + v.strip(" a") + '"') # "bb cc" print('"' + v.strip("c ") + '"') print('"' + v.strip(" c") + '"') # "aa bb" print('"' + v.strip("ac ") + '"') print('"' + v.strip(" ac") + '"') print('"' + v.strip("a c") + '"') # "bb" print('"' + v.strip("") + '"') print('"' + v.strip("a") + '"') print('"' + v.strip("c") + '"') print('"' + v.strip("ac") + '"') # " aa bb cc " # ↑↑ ↑↑ lstrip() can remove zero or more characters(chars) from the left character of a string one by one as shown below:

print(' '.isspace()) print(' '.isspace()) print('\t\n\r\v\x0b\f\x0c\x1c\x1d\x1e\x85\u2028\u2029'.isspace()) # True print('Python 3'.isspace()) print(''.isspace()) # False
