    print(limit)

    date = datetime.datetime.now()

    rnd = random.randrange(2, 6)
    print(rnd)

    count(limit)
    print("after count")

def get_limit():
    limit = 10
    if len(sys.argv) == 2:
        limit = int(sys.argv[1])
    return limit

def count(limit):
    for ix in range(limit):
        div = ix - 12
        show(ix, ix / div)

def show(number, result):
    print(number, result)

 x = 2
 print(x)
 def f(x, y):
    return x+y

 f(4, 5)

Refactoring example with PyCharm

Change variable name (in scope only)

def add(x, y):
    z = x + y
    return z

def multiply(x, y):
    z = x * y
    return z

x = 2
y = 3
z = add(x, y)
print(z)

z = multiply(x, y)
print(z)

Extract method
