num_str [terminology]

Terminology¶

Usage¶

• Use for a string that represents a number.
• It distinguishes the representation from an actual int or float.
• Prefer it over num when the value's type is a string.
• Prefer it over res when the numeric-string meaning matters.

num_str = "".join(parts)
return "0" if num_str[0] == "0" else num_str
