TypeError: User.__init__() missing 1 required positional argument:

In python TypeError: User.__init__() missing 1 required positional argument: we face this error message when we create a class and use __init__() and miss 1 argument or 1 input value then the python interpreter shows this error message, If you want to fix this error you need to just use add argument or input value to your next line code, For more clarification see the below example.

Wrong Code

class User:
    
    def __init__(self,username):
        self.username = username
        print("New user being created...")
     

user_1 = User()
print(user_1.username)


user_2 = User("Blog")
print(user_2.username)

Error Massage

Traceback (most recent call last):
  File "/home/kali/python/webproject/quiz/17day/main.py", line 8, in <module>
    user_1 = User()
TypeError: User.__init__() missing 1 required positional argument: 'username'

Wrong code line

user_1 = User()

Correct code line

user_1 = User("Amol")

• Wrong action: Outside or user_1 = User().
• Correct action: Insite with user_1 = User(“Amol”).

Entire Correct Code line

class User:
    
    def __init__(self,username):
        self.username = username
        print("New user being created...")
     

user_1 = User("Amol")
print(user_1.username)


user_2 = User("Blog")
print(user_2.username)
