Check if second letter is capitalized,

Question

Hi Im is create my own text game, it very basic :-) and it´s starting with enter name, the basic flow is working, to have the first letter capitalized in first name, but if capitalize the second letter also, it´s not working, my idea is only allow first letter capitalized, and program should go back if this condition is not fulfilled I was trying to fix this, by adding

elif i != i.upper()[:2]: print("The second letter was capitalized, please retype your name ")

def input_name():  # Take name as parameter and use it later
    first_name = (input(str("What is your first name? ")))
   sur_name = (input(str("What are your surname? ")))
first_capitalized_letter_first_name = first_name
first_capitalized_letter_sur_name = sur_name
for i in first_capitalized_letter_first_name[:1]:
    if i == i.upper():
        print("Good you can start with capitalized letter when you are writing your first name ")
    elif i != i.upper()[:2]:
        print("The second letter was capitalized, please retype your name ")

It is not clear what do you try to do. post a small code sample and explain. — balderman, Oct 17 '21 at 16:10
Sorry It was my first question, it was some problems to add the code, but it´s added now — Hawkeye, Oct 17 '21 at 16:18
@Hawkeye You're still missing the input, expected output, and actual output (error). — wjandrea, Oct 17 '21 at 16:36

@Peter Trcka Hi Im sorry If i missed to verify the solution, Im newbie in python, so it will take can take some time before I understand how convert to my code, I has not understand how I can use print, into my code, — Hawkeye, Oct 18 '21 at 17:14
@Hawkeye Understood. In your code you are using foor loop and `if` `else` statements to determine whether there is first capital letter, all other letters are lower case. I have send you a code, where I printed what result `istitle()` function returns for different combination of letter in the word. The prints are there to see that `istitile` returns True only if only first letter is capital. — Peter Trcka, Oct 18 '21 at 18:34
@Peter Trcka, thanks for your reply, and your solution is working :-) — Hawkeye, Oct 18 '21 at 18:52

str.istitle() is what you are looking for.

The istitle() method returns True if all words in a text start with a upper case letter, AND the rest of the word are lower case letters, otherwise False.

Symbols and numbers are ignored.

print("Ascsf".istitle())  # True
print("AscsF".istitle())  # False
print("SnakeCase".istitle())  # False
print("Ascsf Doo Goo".istitle())  #True

more clear implementation:

your_name = input("What is your name?")
if your_name.istitle():
    print(f"{your_name} is a valid name")
else:
    print(f"{your_name} is not a valid name, plase select another.")

Check if second letter is capitalized,
