$($Keygen Program$)$ Write a program called keygen.py that accepts lo $($int$)$ and hi $($int$)$ as command$-$line arguments, generates public$/$private keys $($n$,$e$,$d$),$ and writes the keys to standard output, separated by a space. The interval $[$lo$,$hi$)$ specifies the interval from which prime numbers p and q needed to generate the keys are picked.

Accept lo $($int$)$ and hi $($int$)$ as command$-$line arguments Get public$/$private keys as a tuple Write the three values in the tuple, separated by a space
