*Memo for string, bytes and bytearray functions:

*Memo for a string, bytes and bytearray:

str.rstrip() and bytes.rstrip() or bytearray.rstrip() can remove zero or more characters and bytes from the right side of the string and bytes or bytearray 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 bytes or bytearray 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=.
