I am trying to figure out how I can count the uppercase letters in a string.
I have only been able to count lowercase letters:
def n_lower_chars(string):
return sum(map(str.islower, string))
Example of what I am trying to accomplish:
Type word: HeLLo
Capital Letters: 3
When I try to flip the function above, It produces errors:
def n_upper_chars(string):
return sum(map(str.isupper, string))
解決方案message = input("Type word: ")
print("Capital Letters: ", sum(1 for c in message if c.isupper()))
See a demonstration below:
>>> message = input("Type word: ")
Type word: aBcDeFg
>>> print("Capital Letters: ", sum(1 for c in message if c.isupper()))
Capital Letters: 3
>>>
