python 3x Save and call random variables

I've very recently started to learn python so please forgive the novice level of my question.

I'm attempting to have my code create a number of random values, save those values, then allow me to manipulate those random values to create a number of profiles.

I'm currently finding issues with both saving the numbers and finding issues with global and local values

I have this so far (And fully apologize for this layout)

import random

HP = random.randint(30,70)
Strength = random.randint (30,70)       

M_HP = random.randint(30,70)-10
M_Strength = random.randint (30,70)-10


def pilot_print():
    print ("Your pilot HP is " +str(HP))
    print ("Your pilot Strength is " +str(Strength))

def mech_print():
    print ("Your Mech HP is " +str(M_HP))
    print ("Your Mech Strength is " +str(M_Strength))

My issue is that I'm also attempting to put something like

def combine():
    HP+(M_HP/2) = C_HP
    Strength+(M_Strength/2) = C_Strength

My aim is to eventually create a game with character profiles generated randomly.

Would anyone be kind enough to point me in the right direction? Thank you
