How to Create an Infinite Arithmetic Sequence Generator in Python

Build a memory-efficient generator that yields an infinite arithmetic progression and extract the first N values with list comprehension.

generators yield infinite-sequences
Python 
"""Count generator infinite arithmetic progression"""


def arithmetic_counter(start=0, step=1):
    """Generate an infinite arithmetic sequence."""
    current = start
    while True:
        yield current
        current += step


if __name__ == "__main__":
    counter = arithmetic_counter(1, 3)
    result = [next(c…
