Question

(PYTHON please) Write a function that takes, as an argument, a positive integer n, and creates a file, named fourBits.txt, containing n randomly generated four-bit binary strings, each on its own line. Examples of four-bit binary strings include “1111” and “0011”. Name this function fourBitStrings(n).

Answer 1

import random


def fourBitStrings(n):
    f = open('fourBits.txt', 'w')
    for i in range(n):
        number = random.randint(0, 15)
        f.write('0' * (4 - len(bin(number)[2:])) + bin(number)[2:] + "\n")
    f.close()


# Testing the function here. ignore/remove the code below if not required
fourBitStrings(5)  # This write data to file. check file for output.

generated four Bits.txt file..

1110 0111 1111 1000 0001
