rjust in Python

Buy Me a Coffee☕

*Memo for string, bytes and bytearray functions:

• My post explains center().
• My post explains ljust().
• My post explains zfill().
• My post explains expandtabs().
• My post explains encode() and decode().

*Memo for a string, bytes and bytearray:

• My post explains a string.
• My post explains a bytes.
• My post explains a bytearray.

str.rjust() and bytes.rjust() or bytearray.rjust() can right-justify the string and bytes or bytearray set width respectively as shown below:

*Memo:

• The 1st argument is width(Required-Type:int):
  • It's the width of the string and bytes or bytearray respectively.
  • Padding is added to the left side of the string and bytes or bytearray if width is longer than the length of the original string and bytes or bytearray respectively.
  • Don't use width=.
• The 2nd argument is fillbyte(Optional-Defualt:" "-Type:str for str.rjust() or bytes/bytearray for bytes.rjust() and bytearray.rjust()):
  • It's the character and byte to fill the padding of the string and bytes or bytearray set width respectively.
  • It must be one character and byte respectively.
  • Don't use fillbyte=.
