I'm trying to subtract the values in an array with 10 values that the user inputs. So far I can't find how to do that. This is what I have...

g = 0
q = []

for s in range(9):    
    while g < 10:
        n = input()
        q.append(int(n))
        g = g+1

add = sum(Q)

sub =

Answer 1

There are more succinct ways to do this; I've opted instead for readability:

# get our initial input:
n = input()
result = int(n)

# subtract the rest of the user's inputs:
for x in range(9):
    n = input()
    result -= int(n)

# ... do something with the result ...

Answer 2

You don't need to assign all of those to individual variables. At each iteration of the loop, you could just append the newly input value to the array:

q = []
g = 0
while g < 10:
    n = input()
    q.append(int(n))
    g = g + 1

At the end of this loop, q will contain the 10 values that the user entered.

It's not clear to me what needs to be subtracted from what, but that might get you a little closer to where you need to be.

Answer 3

Be pythonic

a = [int(input()) for x in range(10)]

Or for python 2.X

a = [int(raw_input()) for x in xrange(10)]

This gives you a list containing 10 integers.

Then you can q = map(lambda x: x-sum(a), q), which subtracts the sum of user inputs

Answer 4

Just use python API

li = []
for x in xrage(10):
    li.append(input())
result = reduce(lambda x, y: x - y, li)
