- I created this file to find out how binary operations would format output
after I realized that I couldn't k&2 because it was not reliable. I believe I 
now understand it to be that & sets each bit to 0 if either bit is 0, therefore
when running k&2, it was printing the decimal version of the binary output, 
which would be either 2 or 0.

k = (int(input('Give a value for k... ')))
l = k & 1
print(l)
