15. Starts with Specific Number

Write a Python program that starts each string with a specific number.

Sample Solution:

Python Code:

import re
def match_num(string):
    text = re.compile(r"^5")
    if text.match(string):
        return True
    else:
        return False
print(match_num('5-2345861'))
print(match_num('6-2345861'))

Sample Output:

True                                                                                                          
False
