Help a String Get Lucky
Use a while loop to complete the function
get_lucky so that it receives a string
poor_string and an integer
lucky_number as a parameter. Add "7" to
poor_string an amount of times equal to
lucky_number and return the result.
>>> get_lucky("rabbit foot", 3) 'rabbit foot777' >>> get_lucky("shiny penny", 5) 'shiny penny77777'
Hint: You can use the
+= operator to concatenate new stuff to strings.
Another Hint: You might need to keep track of how many times you've added the string "7" somewhere. And watch out for those infinite loops. They're dangerous!
