Why we need to more the comments??
In the given line of code, the comment is explaining what the line does, which is to remove the leading "0b" from the binary representation of the integer a. Comments are useful for making the code more understandable to other developers (or to your future self) who might read the code later.

When using the format, "0b" is not included in the output, as it generates a string of 0s and 1s directly. As for the comment, would "converting to binary string" accurately reflect the operation? If so, I would be happy to implement these changes. Your feedback is valuable.

I think it's fine to remove the comments here. format(_, "b") is much more transparent about its purpose of converting an int to binary, at least compared to str(bin(_))[2:], so if the reader knows what the format function does, then they know what this line of code does. Plus, the variable name a_binary already makes it clear that this line converts a to binary.

b_binary = str(bin(b))[2:] # remove the leading "0b"
a_binary = format(a, "b")
b_binary = format(b, "b")

max_len = max(len(a_binary), len(b_binary))
