Let's write a function to see how long something takes:
def timeit(f):
    start = time.time()
    f()
    print(time.time() - start)

def addem():
    L = []
    for i in range(10000000):
        L.append(i)

timeit(addem)

def timeit(f, *args, **kwargs):
    start = time.time()
    f(*args, **kwargs)
    print(time.time() - start)

def addem(count):
    L = []
    for i in range(count):
        L.append(i)

timeit(addem, 1000)

timeit(addem, 1000)

timeit(addem, 1000)

import random

random.random()

random.randint(0, 3)

def addem(count, maxint):
    L = []
    for i in range(count):
        L.append(random.randint(0, maxint))
    return L

addem(100, 10)

def find(list, item):
    count = 0
    for i in list:
        if item == i:
            return count
        count += 1
    return -1

def f1():
    print("hi")
    
def f2():
    return "hi"

print(f2())

f1()

list = addem(1000, 1000)

x = 10000
list = addem(x, x)
total = 0
for i in range(x):
    if find(list, i) >= 0:
        total += 1
print(total/x)
