Why does my Python code not output anything? [closed]

Question

I wanted to create a Python code where it's a cashier asking questions and putting the inputted products in the dictionary but it doesn't output anything.

def enterProducts():
  buyingData = {}
  enterDetails = True
  while enterDetails:
    details = input("Press A to add product and Q to quit:")
    if details == 'A':
      product = input("Enter product:")
      quantity = int(input("Enter quantity:"))
      buyingData.updata({product: quantity})
    elif details == 'Q':
      enterDetails = False
    else:
      print('Please select a correct option')
    return buyingData

Answer 1

Change .updata to .update and (I don't know the context) I've added if __name__ == "__main__": ...

Working example:

def enter_products():
    buying_data = {}
    enter_details = True
    while enter_details:
        details = input("Press A to add product and Q to quit:")
        if details == 'A':
            product = input("Enter product:")
            quantity = int(input("Enter quantity:"))
            buying_data.update({product: quantity}) #Change
        elif details == 'Q':
            enter_details = False
        else:
            print('Please select a correct option')
        print(buying_data)
        #return buying_data


if __name__ == "__main__":
    enter_products()

Answer 2

Try this

def enterProducts():
  buyingData = {}
  enterDetails = True
  while enterDetails:
    details = input("Press A to add product and Q to quit:")
    if details == 'A':
      product = input("Enter product:")
      try:
          quantity = int(input("Enter quantity:"))
          buyingData.update({product: quantity})
      except:
          print("It should be a integer")
      
    elif details == 'Q':
      enterDetails = False
      return buyingData
  
    else:
      print('Please select a correct option')
    

l = enterProducts()
print(l)

You can add and updates dicts in python rather simply with buyingData[product] = quantity. If you want to insist using the update(), make sure you are writing it correctly - your code has a typo. The correct working example would be:

def enterProducts():
  buyingData = {}
  enterDetails = True
  while enterDetails:
    details = input("Press A to add product and Q to quit:")
    if details == 'A':
      product = input("Enter product:")
      quantity = int(input("Enter quantity:"))
      buyingData.update({product: quantity})
    elif details == 'Q':
      enterDetails = False
      return buyingData
    else:
      print('Please select a correct option')
    
product_quantities = enterProducts()
print(product_quantities)
