Python: Check if String Starts with Number

You can use the isdigit() method of strings to determine if a string starts with a number. Example is as follows:

s = "123abc"
if s[0].isdigit():
    print("字符串以数字开头")
else:
    print("字符串不以数字开头")

Alternatively, you can also use regular expressions to determine if a string starts with a number. For example:

import re

s = "123abc"
if re.match("^\d", s):
    print("字符串以数字开头")
else:
    print("字符串不以数字开头")
