We're excited to share with you our newest video, "How to solve 'TypeError: 'type' object is not subscriptable' when using 'if key in dict.keys():' 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: 'type' object is not subscriptable' when using 'if key in dict.keys():'. Here is a snapshot of the code of the video:

Troubling Scenario: ❗️

dict = type({})
if 'key' in dict.keys():
print("This causes error")


Unwanted Result: 🚫
'TypeError: 'type' object is not subscriptable' when using 'if key in dict.keys():'

Effective Resolution: ✔️

dict = {}
if 'key' in dict.keys():
print("This causes error")


Desired Output: 🏁


In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: Code1 error arises because `dict` is assigned to `type({})`, which is the `dict` type itself, not an instance. Correct by replacing `dict = type({})` with `dict = {}`. 🎯
