How do I make long "IF statement" in python? : So I am trying to make a long if statement where it asks you for a sign up or login, but when I get to the login part there is a syntax error.Any tips?

    
```
    registration = input("Do you have a registration")
if registration == "No":
 name = input("Type your name: ")
 surname = input("Type your surname: ")
 userp1 = name[0]+ surname.capitalize()
 print(userp1)
 password = input("Enter your password\n")
 userInput = input("Type your login details\n")
if userInput == userp1:
     userInput = input("Password?\n")
     if userInput== password:                 
       print("Welocome")
change = input("Do you want to change your username?")
if change == "No":
   print("You logged in as" , userp1)
else:
 userp1 = input("What would your new username be?")
 print("You logged in as",userp1)
else:
    print("Login")
```
