Python file splitter to get around discord size limits

split.py

import sys

maxBytes = 25000000    # max size of a split file part in bytes

if len(sys.argv) > 1:
    filePath = sys.argv[1]
else:
    filePath = input("Enter the path to a file: ")

with open(filePath, "rb") as f1:
    i = 0
    while (read_bytes := f1.read(maxBytes)):
        with open(f"{filePath}.part{i}", "wb") as f2:
            f2.write(read_bytes)
        i += 1
