Python

Part 2: Modify the program to count and print the frequency of each word. Also print which word appears most often.Hint: Use the value of each dictionary item to count the number of times each word appears.

def main():

filename = input('Enter file name: ')

d = {}

with open(filename, 'r') as f:

for line in f:

for word in line.strip().split():

if word not in d:

d[word] = 0

d[word] += 1

print('All unique words in ' + filename + ' is')

print(list(d.keys()))

print('There were ' + str(len(d)) + ' unique words')

main()
