*Memo for string, bytes and bytearray functions:

• My post explains isdecimal(), isdigit() and isnumeric().
• My post explains isalpha() and isalnum().
• My post explains isascii(), isspace(), isprintable() and isidentifier().
• My post explains encode() and decode().

*Memo for a string, bytes and bytearray:

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

keyword.iskeyword() can check if a string or bytes is a Python keyword according to Keywords and isn't empty as shown below:

*Memo:
