Last update on December 31 2024 07:12:07 (UTC/GMT +8 hours)

Write a Python program to find the sequences of one upper case letter followed by lower case letters.

Sample Solution:

Python Code:

import re
def text_match(text):
        patterns = '[A-Z]+[a-z]+$'
        if re.search(patterns, text):
                return 'Found a match!'
        else:
                return('Not matched!')
print(text_match("AaBbGg"))
print(text_match("Python"))
print(text_match("python"))
print(text_match("PYTHON"))
print(text_match("aA"))
print(text_match("Aa"))

Sample Output:

Found a match!
Found a match!
Not matched!
Not matched!
Not matched!
Found a match!
