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
