Question

Using Python: Write a program that takes the size of a file (in bytes) as input from the user, coverts it to the nearest whole number binary prefix (B for byte, KB for kilobyte, MB for megabyte, GB for gigabtye), rounded down. Any file sizes greater than 1024 GB should just be converted to GB.

Answer 1

n = int(input("Enter total number of bytes: "))

if n >= 2 ** 30:
    print("{} bytes is {} GB.".format(n, n // (2 ** 30)))
elif n >= 2 ** 20:
    print("{} bytes is {} MB.".format(n, n // (2 ** 20)))
elif n >= 2 ** 10:
    print("{} bytes is {} KB.".format(n, n // (2 ** 10)))
else:
    print("{} bytes is {} Bytes.".format(n, n))
