Module Result

[EddieG]

I have been writing this code which must result in different result after running the code for heads and tails. I am having only one same result each time and not random.

code:

import random
output={"Heads":0, "Tails":0}
coin=list(output.keys())

for i in range(10000):
    output[random.choice(coin)]=+1

print("Heads:", output["Heads"])
print("Tails:", output["Tails"])

Result in IDLE Shell 3.11.4

Output:
Python 3.11.4 (tags/v3.11.4:d2340ef, Jun  7 2023, 05:45:37) [MSC v.1934 64 bit (AMD64)] on win32

Is there some revision on the code required to get the same result as the textbook example?
Newbie here..

The problem is where you assign the value to 1 (= +1) instead of incrementing the value (+= 1).
