Check if a string contains a number

Most of the questions I've found are biased on the fact they're looking for letters in their numbers, whereas I'm looking for numbers in what I'd like to be a numberless string. I need to enter a string and check to see if it contains any numbers and if it does reject it. The function isdigit() only returns True if ALL of the characters are numbers. I just want to see if the user has entered a number so a sentence like "I own 1 dog" or something. Any ideas?
You can use any function, with the str.isdigit function, like this def has_numbers(inputString): return any(char.isdigit() for char in inputString) has_numbers("I own 1 dog") # True has_numbers("I own no dog") # False Alternatively you can use a Regular Expression, like this import re def has_numbers(inputString): return bool(re.search(r'\d', inputString)) has_numbers("I own 1 dog") # True has_numbers("I own no dog") # False
