Python: How to call a function within a function and insert a list as a parameter for both functions

This is pseudo code just to try explain what I am trying to do simply. 

x = [1, 2, 3, 4, 5, 6]

def func_1(x):
    a = ...
    b = ...
    if a == 2 and b == 5:
        do this to the list...


def func_2(x):
    if a == 6 and b == 2:
        do this to the list...

This is pseudo code just to try explain what I am trying to do simply.

I want to be able to either...

a) run both separate ifs in one function, but to treat them separately

b) have separate functions but have values for a and b carried from the first function to the other (or the adjusted list at the end of the first function taken as the parameter for the second function)

When I call...

x = func_1(x)
x = func_2(x)

it says...

<function func_1 at 0x244384>

it also does the same when I put it all into one function :(

Below is the working (or in this case not working) code. WARNING it is very long. There are probably easier ways to achieve what I want in Deploy_Destroyer_2 but unless this is what the problem is I'm not bothered about advice on this.

def InitBoards():
    Player = [[1]*(6 if x<6 else 12) for x in range(12)]
    Opponent = [[0]*(6 if x<6 else 12) for x in range(12)]

    return Player,Opponent

def Deploy_Destroyer_1(Player):
    rand_col_1 = randint(0,11)
    if rand_col_1 < 6:
        rand_row_1 = randint(0,11)
        return rand_col_1
        return rand_col_2
    else:
        rand_row_1 = randint(6,11)
        return rand_col_1
        return rand_row_1
    if Player[rand_row_1][rand_col_1] == 2:
        Deploy_Destroyer_1(Player)


def Deploy_Destroyer_2(Player):
    if rand_col_1 == 5 and rand_row_1 == 6:
        #can be 1, 2, 3 or 4... in that order below
        rand_position_1 = randint(1,4)
        if rand_position_1 == 1:
            Player[rand_row_1][rand_col_1] = 2
            Player[rand_row_1 + 1][rand_col_1] = 2
        if rand_position_1 == 2:
            Player[rand_row_1][rand_col_1] = 2
            Player[rand_row_1 - 1][rand_col_1] = 2
        if rand_position_1 == 3:
            Player[rand_row_1][rand_col_1] = 2
            Player[rand_row_1][rand_col_1 + 1] = 2
        if rand_position_1 == 4:

print Player
print Opponent

Anybody got any ideas? Or what the above error means?

What is wrong with this:

x = [1, 2, 3, 4, 5, 6]

def f(x):
    a = ...
    b = ...
    if a == 2 and b == 5:
        # do this to the list...
        pass

    if a == 6 and b == 2:
        # do this to the list...
        pass

    return x

x = f(x)

?

(on a side note, the above is legal Python 3.x, as ... is an inbuilt object!)

Lists are mutable objects, so the answer is "just do it". It'll work like magic (while in most cases, it's a pitfall).

And I should've looked more at the details, to get also a and b into the 2nd function's scope, one of many possible solutions would be:

def f1(l):
    …
    return l, a, b

def f2(l, a, b):
    …

f2(*f1(x))

Can't propose a fitting solution if we're just talking in f1, f2, a, and b, instead of problem domains. ;)
