Trouble with variable declaration and assigning in conditional statements (Python)-CodePudding

I'm currently writing some code for a project of mine, though I have been stuck on this for a good bit and It's getting to me.

The idea is to have some code that will show the users previous input, ask them to validate it and see if what they typed is correct than proceed according to a 'yes' or 'no' answer provided by the user.

If they type 'yes' I want the code to continue and commit the data into a database, if they type 'no' I want the code to loop back so they can re-enter any values. The problem is I can't seem to get the code to loop back on itself so the user can input new values, It always just continues on, saving it to the database regardless or throwing a NameError claiming the variable is not defined.

Here's the code:

while True:
  clear()

  print("\nPLEASE INPUT THE REQUIRED DATA.\n")

  IN_NAME = input('Name: ')
  IN_EMAIL = input('Email: ')
  IN_ADDRESS = input('Address: ')
  
  clear()

  print("\nDOES THIS LOOK CORRECT?\n")
  
  print("#--START--#\n")
  print("NAME: "   IN_NAME)
  print("EMAIL: "   IN_EMAIL)
  print("ADDRESS "   IN_ADDRESS)
  print("\n#---END---#\n")
  
  loop_input = None

  while True: 
      answer = input("ENTER YES OR NO: ") 
      if answer == "yes":
          loop_repeat == False
          break 
      elif answer == "no":
          loop_repeat == True
          break
      else: 
          print("PLEASE ENTER YES OR NO.")
          continue 

  if loop_repeat == True:
      continue
  else:
      pass

  cursor.execute("""
    INSERT INTO contacts(name, email, address)
    VALUES (?,?,?)
    """, (IN_NAME, IN_EMAIL, IN_ADDRESS))

  print ( 'Data entered successfully.\n' )

  break

Any help would be greatly appreciated.

simply change from this

  while True: 
      answer = input("ENTER YES OR NO: ") 
      if answer == "yes":
          loop_repeat == False
          break 
      elif answer == "no":
          loop_repeat == True
          break
      else: 
          print("PLEASE ENTER YES OR NO.")
          continue

to this

  while True: 
      answer = input("ENTER YES OR NO: ") 
      if answer == "yes":
          loop_repeat = False
          break 
      elif answer == "no":
          loop_repeat = True
          break
      else: 
          print("PLEASE ENTER YES OR NO.")
          continue

The problem was that you weren't doing an assignement.

== is used for comparisions, while you were using it for assignments (the latter is done using a single =

You can do it function based

def ask_questions():
  clear()

  print("\nPLEASE INPUT THE REQUIRED DATA.\n")

  IN_NAME = input('Name: ')
  IN_EMAIL = input('Email: ')
  IN_ADDRESS = input('Address: ')
  
  clear()

  print("\nDOES THIS LOOK CORRECT?\n")
  
  print("#--START--#\n")
  print("NAME: "   IN_NAME)
  print("EMAIL: "   IN_EMAIL)
  print("ADDRESS "   IN_ADDRESS)
  print("\n#---END---#\n")

  while True: 
      answer = input("ENTER YES OR NO: ") 
      if answer == "yes":
          return IN_NAME, IN_EMAIL, IN_ADDRESS
      elif answer == "no":
          return ask_questions()
      else: 
          print("PLEASE ENTER YES OR NO.")
          continue 

name, email, address = ask_questions()
cursor.execute("""
INSERT INTO contacts(name, email, address)
VALUES (?,?,?)
""", (name, email, address))
print('Data entered successfully.\n')
