# write python code to...
# create a list holding the strings "alpha", "beta" and "banana"
# using a loop, get two more strings from the user and append them to that list
# using a loop, alter the list so that every string has its position (index) prepended to it
# e.g. it might end up being "0alpha", "1beta", "2banana", "3bacon", "4cheese"
# using a loop, calculate the total number of characters in all 5 strings in the list
# get a string from the user and replace the third string in the list with it
# create a list containing 4 real numbers (floats)
# using a loop, create another list that holds the cosine of each number in that list
# (recall that the built-in math module has a cosine function named cos)
