Hi guys, i'm just learning how to program in Python and i'm have some problems...

I'm testing the functions and this is my code:

##I want a simple code that tells you to type name and age then the program will tell it again.
##But i'm having problems with the while loop. I want it to ask again if an int is not typed for the age, but
##this code apparently is not enough. I've tried a lot of things, with if and exceptions, but i just can't.
##Can you help me please?

def display(nome, idade):
print("Seu nome é", nome, "e sua idade é", idade) #Your name is: // Your age is:

age = None
name = input("Qual o seu nome?") #What's your name?
while type(age) != int:
age = input("Qual a sua idade?") #How old are you?
print("O valor digitado não é um número inteiro") #The typed value is not an integer
display(name, age)

The input is a type str. So you have to convert to type int if you want to. Or you can use isalnum or isdigit methods.

I

n [1]: age = '132'

In [2]: type(age)
Out[2]: str

In [3]: age.isalnum()
Out[3]: True

In [4]: age.isalnum??
Docstring:
S.isalnum() -> bool

Return True if all characters in S are alphanumeric
and there is at least one character in S, False otherwise.
Type:      builtin_function_or_method

In [5]: age.isdigit()
Out[5]: True

In [6]: age.isdigit??
Docstring:
S.isdigit() -> bool

Return True if all characters in S are digits
and there is at least one character in S, False otherwise.
Type:      builtin_function_or_method
