Hello, Dedicated Coders! 🖥️💡
We're excited to share with you our newest video, "How to solve TypeError: 'type' object is not subscriptable - occurs when using a type like List or Tuple without importing from typing in Python less than3.9. 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 - occurs when using a type like List or Tuple without importing from typing in Python less than3.9.. Here is a snapshot of the code of the video:
Troubling Scenario: ❗️
value: List[int] = [1, 2, 3]
Unwanted Result: 🚫
TypeError: 'type' object is not subscriptable - occurs when using a type like List or Tuple without importing from typing in Python less than3.9.
Effective Resolution: ✔️
from typing import List
value: List[int] = [1, 2, 3]
Desired Output: 🏁
This code does not produce any output when run.
In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: In Code1, `List` is used without importing from `typing`, causing a subscriptability error. Code2 corrects this by importing `List` from `typing`, enabling subscriptable annotations for lists. 🎯
