This assignment is based on Exercise 8.4 from your textbook. Each of the following Python functions is supposed to check whether its argument has any lowercase letters.

For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect.

# 1

def any_lowercase1(s): for c in s: if c.islower(): return True else: return False

# 2

def any_lowercase2(s): for c in s: if 'c'.islower(): return 'True' else: return 'False'

# 3

def any_lowercase3(s): for c in s: flag = c.islower() return flag

# 4

def any_lowercase4(s): flag = False for c in s: flag = flag or c.islower() return flag

# 5

def any_lowercase5(s): for c in s: if not c.islower(): return False return True
