Prompt of input function including variables

Question

I have the following script:

#! /usr/bin/python3
name1 = input('Enter the name of first person ')
name2 = input('Enter the name of second person ')
age1 = int(input("Enter the first age "))
age2 = int(input('Enter the second age '))

print('%s' %name1,  'is %d' %age1, 'years and %s' %name2,  'is %d' %age2, 'years')

agex = age1

age1 = age2
age2 = agex


print('Now we swap ages: %s' %name1,  'is %d' %age1, 'years and %s' %name2,  'is %d' %age2, 'years')

What I'd want is to ask for ages including the name entering in the name questions, I mean, something like:

age1 = int(input("Enter the age of", name1))

But that does not work...

So if you answer as first personame John, so you should get:

Enter the age of John:

How can I do that?

Please make your question consistent ... your variables are `name1`, yet you then talk about `nom1`. — donkopotamus, Oct 20 '15 at 22:54
Or the `%` formatting you demonstrated that you already know about. — TigerhawkT3, Oct 20 '15 at 23:08
Off topic, but to swap variables you can use `age1, age2 = age2, age1` — donkopotamus, Oct 20 '15 at 23:09
@TigerhawkT3, my question was specific to input function, you're right that I already know about "% formatting" but I've tried something wrong, perhaps. I think that answers are quite useful for other people. But feel free to do what you want :) — sebelk, Oct 21 '15 at 00:09
"The answers are quite useful"? They're all present in the duplicate. — TigerhawkT3, Oct 21 '15 at 00:09

Try

age1 = int(input("Enter the age of {}:".format(name1)))

or if you prefer string interpolation:

age1 = int(input("Enter the age of %s:" % name1))

input() takes a string as its parameter so just create a string with your variable. ie, if firstname == 'John':

lastname = input('What is the last name of '+firstname+': ')

age1 = int(input("Enter the first age " + name1))

You need to concatenate the strings. You were so close ...
