Python - while loop count

I need to know the score of "heads" and "tails" in 5 times tossing the coin. For example, the result should be: - Heads was 3 times - Tails was 2 times

import random
print("Heads or tails. Let's toss a coin five times.\n")
toss = 1

while toss <= 5:
    coin = ["HEADS", "TAILS"]
    y = random.choice(coin)
    print("Toss number:", toss, "is showing:", y)
    toss = toss + 1

I have made changes to your code to count the frequency of each coin side (Heads or Tails),

import random
print("Heads or tails. Let's toss a coin five times.\n")
toss = 1
counts = {"HEADS": 0, "TAILS": 0}

while toss <= 5:
    coin = ["HEADS", "TAILS"]
    y = random.choice(coin)
    counts[y] += 1
    print("Toss number:", toss, "is showing:", y)
    toss = toss + 1

print("Heads was " + str(counts["HEADS"]) + " times - Tails was " + str(counts["TAILS"]) + " times")

Create two variables, initialize them to 0, check the result of the coin toss in a if block and add accordingly.

heads, tails = 0, 0
if y == "HEADS":
    heads += 1
else:
    tails += 1

return (heads, tails)

One simple solution would be to let toss be a list of coin toss results. Starting with an empty list, you could loop until the list contained 5 results and on each toss push a new member into the list. That way you end up with a single data structure that contains all the information you need about the tosses.

You should have two variables, head and tail:

import random
print("Heads or tails. Let's toss a coin five times.\n")
head = tail = 0

for i in range(5):
    coin = ["HEADS", "TAILS"]
    y = random.choice(coin)
    print("Toss number:", i, "is showing:", y)
    if y == "HEADS":
        head += 1
    elif y == "TAILS":
        tail += 1

Or, a better solution would be having a dictionary with keys representing heads and tails, with the value representing the count.
