Python 3.3.2 error indexing arrays

Question

I am new to python and just need a tad of help with this test program I am using to revise my learning.

I am getting an error on the last question of this program:

var1 = [["Carl", 1], ["Josh", 3]]
input("Please choose var1[0] or var1[1]")
if input == var1[0]:
    input("would you like to print the string or the int?(0 = str, 1 = int)")
    if input == 0:
        print(var1[0[0]])
    else:
        print(var1[0[1]])

else:
    input("would you like to print the string or the int?(0 = str, 1 = int)")
    if input == 0:
        print(var1[1[0]])
    else:
        print(var1[1[1]])

You're looking for var[0][0] not var[0[0]]

You have three problems:

You are indexing your array wrong. The syntax should be like this: print(var1[0][0])
You need to compare the input with strings, since input returns a string object.
You need to assign that input to a variable so that you can use it later. Right now, you are comparing with the built-in input itself.

Here is your code with those problems fixed:

var1 = [["Carl", 1], ["Josh", 3]]
user_input = input("Please choose var1[0] or var1[1]")
if user_input == var1[0]:
    user_input = input("would you like to print the string or the int?(0 = str, 1 = int)")
    if user_input == '0':
        print(var1[0][0])
    else:
        print(var1[0][1])

else:
    user_input = input("would you like to print the string or the int?(0 = str, 1 = int)")
    if user_input == '0':
        print(var1[1][0])
    else:
        print(var1[1][1])

That's what fast problem solving is ;-).

The result of input("whatever") doesn't seem to be assigned anywhere, and the comparisons are currently with the function input.
