string.digits

digits

The string '0123456789'. Used to test for digit characters and to generate numeric codes.

Syntax

string.digits  # '0123456789'

Watch out with in: this is a plain string, so '12' in string.digits is True (it is a substring), while '21' is False. To test a whole string use s.isdigit() or set(s) <= set(string.digits). Note also that the constant is ASCII-only: an Arabic-Indic digit like '٣' passes isdigit() but is absent from string.digits, which makes a membership test against it stricter than isdigit().

Examples

import string
print(string.digits)  # → 0123456789
print('5' in string.digits)  # → True
digits_only = [c for c in 'abc123' if c in string.digits]  # → ['1','2','3']

import string
import random
pin = ''.join(random.choices(string.digits, k=4))  # → '4-значный PIN'
print(len(string.digits))  # → 10
