Python: condition between two values, in both directions quickly

Solved

Good evening!
I am working on a Python project that requires as much speed as possible; my level is rather beginner.
So, in one part of my code, I use a condition 
if
that needs to test if a value is between two others, like 
a<machin<b
. But the condition must also work for 
a>machin>b
because a and b are variables and can be negative! Is there a simple function to check 
a>machin>b and a<machin<b
more logically?

Thank you very much!

      Ah ! I meant 
      a>machin>b or a<machin<b
      ! OR of course !
      (And so I know that we can do 
      if a>machin>b or a<machin<b
      , but isn't there a function like if machin between(a,b) ?)

        Good evening,

        No, it doesn't exist. But it's not hard to make. 

        def number_between(v, a, b, equal=False): if a > b: a, b = b, a return a < v < b if not equal else a <= v <= b


        In terms of speed, well it's a Python function, and in terms of usefulness, meh, usually we know what we need to compare in a program.
