Blackjack game doesnt work

Hey, i'm kinda new to pyhton and i tried to create a simple blackjack game. it doesn't entirely work as intended. when i do stand i get an never ending loop of "do you want to hit or stand? [h/s]" or things like this
do you want to hit or stand? [h/s]h
Your Cards are: [10, 2, 4]
total: 16 

the computer has: [9, 6, 4]
total: 19 

do you want to hit or stand? [h/s]s
Your Cards are: [10, 2, 4, 3]
total: 19 

Draw
do you want to hit or stand? [h/s]s
Your Cards are: [10, 2, 4, 3, 4]
total: 23 

You lost
the computer stands with a total of: 19
do you want to hit or stand? [h/s]s
Your Cards are: [10, 2, 4, 3, 4, 2]
total: 25 

You lost

before the code stops and i cant figure out why it does this. it gives a loop of do you want to hit or stand, until it suddenly stops and suddenly adds another card without me hitting

A:

The problem is that "drawPlayerCard()" calls "drawComputerHand()" and "drawComputerHand()" calls "hitStand()".
Explanation: 
first problem in "drawPlayerHand()":
    if len(playerHand) < 2:
        drawPlayerCard()
    drawComputerHand()

When your if statement is true, "drawPlayerHand()" is executed a second time. This means that "drawComputerHand()" is also executed 2 times.
And you have the same problem in "drawComputerHand()": 
    if len(computerHand) < 2:
        drawComputerHand()
    hitStand()

Try to fix it yourself. If you arent able to fix it, I can post some more code.
