# Help in python blackjack exercise

I have no idea about what is wrong with my code, tried thousands of times, but it is showing error every time.

My code:

def value_of_card(card):
“”"Determine the scoring value of a card.

``````:param card: str - given card.
:return: int - value of a given card.  See below for values.

1.  'J', 'Q', or 'K' (otherwise known as "face cards") = 10
2.  'A' (ace card) = 1
3.  '2' - '10' = numerical value.
"""

face_cards = ('J', 'Q','K')
if card in face_cards:
return 10
if card == 'A':
return 1
else:
return int(card)
``````

def higher_card(card_one, card_two):
“”"Determine which card has a higher value in the hand.

``````:param card_one, card_two: str - cards dealt in hand.  See below for values.
:return: str or tuple - resulting Tuple contains both cards if they are of equal value.

1.  'J', 'Q', or 'K' (otherwise known as "face cards") = 10
2.  'A' (ace card) = 1
3.  '2' - '10' = numerical value.
"""

card1 = value_of_card(card_one)
card2 = value_of_card(card_two)
if card1>card2:
return card_one
if card2>card1:
return card_two
else:
return card_one,card_two
``````

def value_of_ace(card_one, card_two):
“”"Calculate the most advantageous value for the ace card.

``````:param card_one, card_two: str - card dealt. See below for values.
:return: int - either 1 or 11 value of the upcoming ace card.

1.  'J', 'Q', or 'K' (otherwise known as "face cards") = 10
2.  'A' (ace card) = 11 (if already in hand)
3.  '2' - '10' = numerical value.
"""
total = value_of_card(card_one) + value_of_card(card_two)

if 'A' in (card_one, card_two) and total < 11:
return 11
else:
return 1
``````

The error:

Can anyone help me?

Try scrolling lower and clicking on another “failed test” box to expand, if needed. Other tests (variants) will have more details.

Note, you can format your code here to make it readable by putting three backticks (```) on a line before and after your code.
