Python List Comprehension Error: Unexpected Output

Question

I'm encountering an unexpected output while using list comprehension in Python. I'm trying to create a list of squared values for even numbers in a given range, but the result is not what I anticipated. Here's the code I'm using:

even_numbers = [x for x in range(10) if x % 2 == 0]
squared_values = [x**2 for x in even_numbers]

print(squared_values)

I expected the output to be [0, 4, 16, 36, 64], but instead, I'm getting [0, 4, 16]. It seems like the last even number (8) and its corresponding squared value (64) are missing.

Can someone help me understand why this is happening and how to correct my list comprehension code to get the desired output? Is there something I'm overlooking in my approach? Your insights would be greatly appreciated. Thank you!

Answer 1

your code is working fine and the output is

[0, 4, 16, 36, 64]

its your code. I have only copy past it into the playground.

sarthak jain ,

As you provided the range upto 10 and also checking the condition whether it is even as ....8 a even number is included within the range 10...

Then how could it be get missed.??..rerun the code again and see...👍

Answer 3

As already told, the code produces the expected output.

But we can do the calculation in one list comprehension, instead of using 2 of them.

...
squared_values = [x**2 for x in range(10) if x % 2 == 0]
