How to check if a character is upper-case in Python?

Question

I have a string like this

>>> x="Alpha_beta_Gamma" >>> words = [y for y in x.split('_')] >>> words ['Alpha', 'beta', 'Gamma'] 

I want output saying X is non conformant as the the second element of the list words starts with a lower case and if the string x = "Alpha_Beta_Gamma" then it should print string is conformant

Answer 1

To test that all words start with an upper case use this:

print all(word[0].isupper() for word in words) 

Answer 2

Maybe you want str.istitle

>>> help(str.istitle) Help on method_descriptor:  istitle(...)     S.istitle() -> bool      Return True if S is a titlecased string and there is at least one     character in S, i.e. uppercase characters may only follow uncased     characters and lowercase characters only cased ones. Return False     otherwise.  >>> "Alpha_beta_Gamma".istitle() False >>> "Alpha_Beta_Gamma".istitle() True >>> "Alpha_Beta_GAmma".istitle() False
