When given a position of an item in a list, how do I print that value?

I have a list with some numbers in it. The user enters the position of the item they want to print. For example:

 L = [1,2,3,4]
 input = 1
 output = 2

So the user wants to print the number in position 1 so the output will be 2. I tried the following but it didn't work:

input = int(input("Enter position: "))
for i in L:
    print(input[i])

List is a data structure which stores data using index number. suppose you have list called 

l = ['a','b','c']

Index number of 'a' is 0 , 'b' is 1 , 'c' is 2

so list[index] will give you the element at that index.

l[2] = 'b'

There for no need to use a for loop, if you already know the index number.

If you want to stick to the original code, try this:

L = [1,2,3,4]
input = 1
output = 2
input = int(input("Enter position: "))
for i in L:
    print(L[input])

Your problem is that you indexed the input, not the list. This prints it 4 times just to let you know.

You could use something simple like:

chooseFrom = [1,2,3,4]
choice = int(input(">"))
print(chooseFrom[choice])

What about remove this loop and try print(L[input])?

You don't need the for loop 

L = [1,2,3,4]
input = int(input("Enter position: "))
print(L[input])
