rstrip in Python

Buy Me a Coffee☕

*Memo for a string and byte string(bytes and bytearray) functions:

• My post explains strip().
• My post explains lstrip().

*Memo for a string and byte string(bytes and bytearray):

• My post explains a string.
• My post explains a byte string.

str.rstrip() and bytes.rstrip() or bytearray.rstrip() can remove zero or more characters and bytes from the right side of the string and byte string one by one respectively as shown below:

*Memo:

• The 1st argument is chars(Optional-Defualt:None-Type:str for str.rstrip(), Bytes-like object for bytes.rstrip() and bytearray.rstrip() or NoneType):
  • It's the zero or more characters and bytes to remove from the right side of the string and byte string one by one respectively.
  • Its each character and byte are considered one by one so it's not a suffix respectively.
  • If it's not set or None, " " is set.
  • Don't use chars=.
