how to check if a string contains any numbers?

Answer 1

Here is version that uses any() function:

inp = 'this is 1 person'
print(True) if any(i.isdigit() for i in inp) else print(False)

Answer 2

import re
a = '[0-9]'
print(bool(re.findall(a,your_string)))

Answer 3

madeline , there seems to be an issue with the code you presented.

import re
your_string = 'f123de'
a = '[0-9]'
print(bool(re.match(a,your_string))) # missing closing parenthesis at the end of the line

The regex only find digits if they are at the beginning of the string. When the string starts with a character it returns False.

Answer 4
