int' object is not subscriptable

Question

Problem:

I was trying to write code, in which I’ll get someone's name and age but I keep getting this error: 'int' object is not subscriptable error.

Here is my code

name = raw_input("What's your name? ")
age = raw_input ("how old are you? ")
x = 0
int([x[age]])
twentyone = 21 - x
print "Hello, " + name+ " you will be 21 in: " + twentyone + " years."

Any clues?

Answer 1

The problem occurred when you wrote x=0 and then int([x[age]]). When you declared x=0, it created an int variable which value is 0. Then again when you wrote int([x[age]]), compiler assumed it as it an array but you didn’t declare it as an array.
The whole program would be like this

name = raw_input("What's your name? ")
age = raw_input ("how old are you? ")
x = 0
x = int(age)
twentyone = 21 - x
print "Hello, " + name+ " you will be 21 in: " + str(twentyone) + " years."

It should work fine now.
