give this as a list comprehension: `def square(num): if num not in range(1, 65): raise valueerror("must be between 1 and 64") else: return 1 << (num - 1)` in python

Here's how you can convert the given code into a list comprehension:

main.py
def square(num):
    if num not in range(1, 65):
        raise ValueError("must be between 1 and 64")
    else:
        return 1 << (num - 1)

numbers = [square(num) for num in range(1, 65)]
191 chars
8 lines

In this list comprehension, we iterate through the range of numbers from 1 to 64. For each number, the square function is called to calculate the square using bit shifting (1 << (num - 1)). The resulting values are collected in the numbers list.

However, it's important to note that list comprehensions are generally used for creating lists, and in this case, the square function already returns a single value. So, using a plain loop would be more appropriate in this specific scenario.
