Finding if a character is a capital in a string (python)

Question

The code that I have so far is:

password = input("Please enter a password: ")
letter = len(password)
if letters <= 5:
print ("WEAK")
elif

I know the answer is probably really obvious but I just can't see it - what i need it to be able to see whether the letters are capitals. There is other stuff that I need aswell but I'm working through it one step at a time. Please help?

`if 'A' <= c <= 'Z'` where `c` is the character you're checking — m_callens, Feb 07 '17 at 19:12

Do you want to know whether any, or whether all characters in the string are capitals? In either case, how should non-alpha characters and characters from scripts without upper/lower distinction be treated? — das-g, Feb 07 '17 at 20:15

String has isupper function:

Use it as follow:

 >>> 'e'.isupper()
 False
 >>> 'E'.isupper()
 True
 >>> 'Ennn'.isupper()
 False
 >>> 'EEE'.isupper()
 >>> 'eee'.isupper()
 False
 >>> 'EEEEe'.isupper()
 False

If you want to check if at lest one char is upper, you can use any

 >>> any([x.isupper() for x in list('eeeeE')])
 True
 >>> any([x.isupper() for x in list('eeee')])
 False
 >>> any([x.isupper() for x in list('EEEE')])
 True

You're quite in love with lists, it seems. `any(x.isupper() for x in 'eeeeE')` works as well (if not better). — Stefan Pochmann, Feb 07 '17 at 21:05
