Описание: Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve TypeError: method() takes 1 positional argument but 2 were given. 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: method() takes 1 positional argument but 2 were given.. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

class MyClass:
def method(self):
pass

obj = MyClass()
obj.method(1)


Unwanted Result: 🚫
TypeError: method() takes 1 positional argument but 2 were given.

Effective Resolution: ✔️

class MyClass:
def method(self, arg):
pass

obj = MyClass()
obj.method(1)


Desired Output: 🏁


In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: In Code1, `method` accepts no parameters besides `self`. Adding `arg` in its definition resolves the error, as demonstrated in Code2, where `method` is correctly defined to accept an additional argument. 🎯
