What function is needed to complete the program
To return the index of an item in a list, we make use of the index function.
In this case, the complete program will be:
myList = [12, 5, 7, 3, 25]
print(myList.index(7))
At the end of program compilation and execution, the index of 7 (which is 2) will be returned/printed.
