$3\mathrm{.}14$

Exercise $3\mathrm{.}1.$ Write a function named right$\_$justify that takes a string named $s$ as a parameter and prints the string with enough leading spaces so that the last letter of the string is in column $70$ of the display.

$$ right$\_$justify$(\text{'}$monty$\text{'})$ monty

Hint: Use string concatenation and repetition. Also, Python provides a built$-$in function called len that returns the length of a string, so the value of $1$ en $(\text{'}$monty$\text{'})$ is $5.$
