*Memo for string, bytes and bytearray functions:
- My post explains center().
- My post explains rjust().
- My post explains zfill().
- My post explains expandtabs().
*Memo for a string, bytes and bytearray:
str.ljust() and bytes.ljust() or bytearray.ljust() can left-justify(left-align) 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 right side of the string and bytes or bytearray if
widthis 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:strforstr.ljust()orbytes/bytearrayforbytes.ljust()andbytearray.ljust()):- It's the character and byte to fill the padding of the string and bytes or bytearray set
widthrespectively. - It must be one character and byte respectively.
- Don't use
fillbyte=.
- It's the character and byte to fill the padding of the string and bytes or bytearray set
