How to call multiple functions sequentially

[Mayo]

Hello guys, I am trying to learn Python and I wonder if there is a better, more efficient solution to this.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

def firstCalc():     a = 2+2     return a   def secondCalc(a):     b = 3+a     return b   def thirdCalc(b):     c = b+7     return c     # Option 1 x = thirdCalc(secondCalc(firstCalc())) print(x)   # Option 2 a = firstCalc() b = secondCalc(a) c = thirdCalc(b) print(c)

I have a code which i seperated in 3 functions to have an easier overview of the code. I use the value I retrieve from the first function in the second function, and the second value in the third function.
Can you tell me if Option 1 or 2 is more efficient? Or maybe if there is a cleaner way to use multiple functions.
Thanks

In my opinion the Option#2 is better and should be preferred over Option#1 - more clean, readable and easy to follow the flow of execution
