Hello, Dedicated Coders! 🖥️💡
We're excited to share with you our newest video, "How to solve TypeError: sequence item 0: expected str instance, int found when using str.join(). 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: sequence item 0: expected str instance, int found when using str.join().. Here is a snapshot of the code of the video:
Troubling Scenario: ❗️
my_list = [1, 'hello', 3]
print(''.join(my_list))
Unwanted Result: 🚫
TypeError: sequence item 0: expected str instance, int found when using str.join().
Effective Resolution: ✔️
my_list = [1, 'hello', 3]
print(''.join(str(item) for item in my_list))
Desired Output: 🏁
1hello3
In this detailed walkthrough, we will illuminate 💡 the underlying cause of this error, and offer a comprehensive explanation: Code1 fails because `join()` expects strings but `my_list` contains integers. Code2 fixes this by converting each item to a string using a generator expression within `join()`. 🎯
