To check if a character is upper-case, we can simply use isupper() function call on the said character.
example
print( 'Z'.isupper()) print( 'u'.isupper())
Output
True False
We can also check it using range based if conditions.
example
def check_upper(c):
if c >= 'A' and c <= 'Z':
return True
else:
return False
print check_upper('A')
print check_upper('a')Output
This will give us the output:
True False
