Hey, thank you for appreciating our work. We are glad to have helped. Do check out our other tutorial videos and subscribe to us to stay connected. Cheers :)
Thank you so much for this video. Sir I am little bit confused that Do I really need to learn c,c++ to start with python?. Can I start learning sql without learning other programming language? Will it be beneficial for me ?
Hi In Python, the is identity operator is used to check if two variables refer to the same object in memory. It compares the memory addresses of the objects rather than their values. In your case, you have two variables, x and y, with the values 505 and 500 + 5 respectively. Although the values are the same, Python treats them as separate objects with potentially different memory addresses. However, due to a feature called ""integer caching"" in Python, small integers between -5 and 256 (inclusive) are cached and reused for efficiency. This means that if you create multiple variables with values within this range, they will refer to the same memory address. This optimization is done to save memory and improve performance for commonly used small integers. Since both 500 + 5 and 505 fall within the range of cached integers, Python optimizes and assigns them the same memory address. As a result, when you compare their identities using the is operator, you get True. It's important to note that this behavior may vary across different Python implementations or versions, as it is an implementation-specific optimization. Therefore, it's recommended to use the == operator for value comparisons and the is operator for identity checks only when necessary.

Can you make video on using raspberry pi with Ubuntu server as server I mean I want to host a Django page using raspberry pi...
What a coincidence... Just started with summer training in my college for Python
Thanks for the video buddy!!! 💕💕

when i was comparing my identity operators, where x = 505 and y = 500 + 5, the id's of both were the same, could you explain why could that happen?
