Write $($define$)$ a function named count$\_$caps, that takes one argument $($you can safely assume that arguments will always be a str with a length of at least one$).$ When this function is called, it should return an int that indicates the total number of capital letters in the argument.

Examples:

count$\_$caps$(\text{'}$HeLLo$!\text{'})$ will return $3$

count$\_$caps$(\text{'}$Bob Smith'$)$ will return $2$

count$\_$caps$(\text{'}$abcdefg$\text{'})$ will return $0$

Hints:

the isupper function might come in handy for this problem.

You may wish to write some additional code to test your function. Please be sure that you delete $($or comment out$)$ any test code before you submit your solution. The only code in your solution when you submit should be the required function definition.
