How to fix TypeError: __new__() missing required positional arguments: 'var2... in Python

Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve TypeError: __new__() missing required positional arguments: 'var2', 'var3' in Python". 🎥 This series is meticulously designed to arm you with knowledge 🧠 and skills 🛠️ to overcome frequent coding challenges.

Today, we will decipher 🔎 and resolve a common error faced by Python coders: the bit hard to solve TypeError: __new__() missing required positional arguments: 'var2', 'var3'. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

class CustomClass:
def __new__(cls, var1, var2, var3):
return super(CustomClass, cls).__new__(cls)

obj = CustomClass(1)

Unwanted Result: 🚫
TypeError: __new__() missing required positional arguments: 'var2', 'var3'

Effective Resolution: ✔️

class CustomClass:
def __new__(cls, var1, var2, var3):
return super(CustomClass, cls).__new__(cls)

obj = CustomClass(1, 2, 3)

Desired Output: 🏁

Traceback (most recent call last):
obj = CustomClass(1, 2, 3)
TypeError: object.__new__() takes exactly one argument (the type to instantiate)

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: In Code1, the error occurs because `CustomClass`'s `__new__` method expects three arguments, but only one was provided. Code2 correctly passes three arguments, thus it doesn't result in an error. 🎯
