Line 2: We import the os module.
Line 3: We import the array module.
Lines 6 to 9: We initialize arrays with unicode characters.
Line 12: We open file object f for writing.
Line 16 to 21: We append array to file object f using the array.tofile().
Line 24: We close the file object f.
Line 28: We open the file object f for reading.
Line 31: We read from the file object f.
