How to fix TypeError: unsupported operand type(s) for +: 'dict' and 'dict' in Python

Hello, Dedicated Coders! 🖥️💡

We're excited to share with you our newest video, "How to solve TypeError: unsupported operand type(s) for +: 'dict' and 'dict' 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: unsupported operand type(s) for +: 'dict' and 'dict'. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

dict1 = {'a': 1}
dict2 = {'b': 2}
result = dict1 + dict2

Unwanted Result: 🚫
TypeError: unsupported operand type(s) for +: 'dict' and 'dict'

Effective Resolution: ✔️

dict1 = {'a': 1}
dict2 = {'b': 2}
result = {**dict1, **dict2}

Desired Output: 🏁
{'a': 1, 'b': 2}

In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: Code1 attempts to add two dictionaries using '+', which isn't supported in Python, causing a TypeError. Code2 correctly merges two dictionaries using unpacking (**), resolving the error in Code1. 🎯
