Question

Suppose I use this block of code very often in my Python file

if x == 1:
  x += 1
else:
  x -= 1

Is there a way to “copy” this code, so that I don’t have to type these four lines repeatedly throughout the file?

Answer 1

Yes define yourself a function for it:

def flip_member(x):
    if x == 1:
        x += 1
    else:
        x -= 1
    return x

Then you can call the function from anywhere in your code instead of rewriting the same logic.
