Beginner code help

[SuperNova]

Sorry for repost

I am new to Python and would appreciate some greatly needed help. I am using functions with csv files and my code doesn't seem to work, please can you help:

x = 0
score = x
import csv

datafile = open('questions.csv', 'r')
myreader = csv.reader(datafile)

print ("Welcome to the Quiz, please choose a quiz number. \n 1.Sports \n 2.Geography")
choice = input()
    
if choice == "1":
    Sportsmenu()

if choice == "2":
            print ("Geography")

def Sportsmenu():
    print ("Welcome to the Sports quiz, please choose a difficulty level. \n 1.Easy \n 2.Medium \n 1.Hard")
choice = input()
    
if choice == "1":
        def easysports():
            if choice == "2":
                print ("Medium")

def easysports():
    datafile = open('questions.csv', 'r')
myreader = csv.reader(datafile)
print("Welcome to Easy Sports")
for row in myreader:
    print(row[0])
    answer1 = input("Please enter your answer ")

if answer1.lower() == (row[2]):  
    print("Correct")
    x = x + 1   
else:
    print("Incorrect")

print(row[1])
answer2 = input("Please enter your answer ")
if answer2.lower() == (row[3]):       
    print("Correct")
    x = x + 1   
else:
    print("Incorrect")


score = (x / 2) * 100
name = input("What is your name? ")
print(name, x, "out of 2, your score is", score,)

writefile = open("scores.csv","a")
writefile.write(name + "," + score+ "\n")
writefile.close()
print("Score added to file")

Error:

Traceback (most recent call last):
  File "//12144domain.sch/userdata$/users/staff/miahn/Desktop/Works/test.py", line 13, in <module>
    Sportsmenu()
