def main() :

phrase = input("Give the phrase: ")

words = phrase.split() # get the words in a list

# generate the acronym string

acro = "" # intialize

for w in words: # loop through the list of words

acro += w[0] # add first character

acro = acro.upper() # capitalize

print(acro)

Make a function out of above program that takes a phrase as a parameter and returns its acronym. Then write a program that asks the user for an input file name and an output file name. The program should then open the input file, treat whatever is on each line as a phrase and make its acronym using the function. It should print the acronyms, one per line to the output file. Assume that the input file will be already present in your default Python folder. The output file will be expected to get saved to the same folder.
