Python – Modify for-loop variable

I got this function:

numbers = [3, 4, 6, 7]

for x in numbers:
    a = 5 - x
    b = 5 + x
    c = 5 * x
    print(x, a, b, c)

What it exactly does doesn’t matter, only the x is relevant.

I want modify x so that:

for x in numbers:
    a = 5 - (x + 2)
    b = 5 + (x + 2)
    c = 5 * (x + 2)
    print((x + 2), a, b, c)

But obviously adding + 2 everywhere is annoying, so I just want to have another value for x.

Ofcourse I could make another variable like this:

for x in numbers:
    modifiedX = x + 2
    a = 5 - modifiedX
    b = 5 + modifiedX
    c = 5 * modifiedX
    print(modifiedX, a, b, c)

But I’m curious if I could get the same result without adding another line, like:

for x + 2 in numbers:
    a = 5 - x
    b = 5 + x
    c = 5 * x
    print(x, a, b, c)

or this:

x + 2 for x in numbers:
    a = 5 - x
    b = 5 + x
    c = 5 * x
    print(x, a, b, c)

Both of these last 2 code blocks aren’t correct Python syntax, so I’m curious:
Is there is a correct method out there to have a modified version of x without adding more lines?

Note: I still want to keep the original numbers list, so Im not looking for changing the numbers in the list directly.

>Solution :

You can use map() to generate a new iterable that contains the elements of numbers incremented by 2. Since map() creates a new iterable, the original list isn’t modified:

numbers = [3, 4, 6, 7]

for x in map(lambda x: x + 2, numbers):
    a = 5 - x
    b = 5 + x
    c = 5 * x
    print(x, a, b, c)

This outputs:

5 0 10 25
6 -1 11 30
8 -3 13 40
9 -4 14 45
