python 1

program 1

that 1

checks 1

the 2

frequency 1

of 1

words 1

Answer 1

Explanation:

Here is the code which takes the filename from the user in which the lines are stored.

Then the file is opened and the words are stored inside a list.

Then, all the words are converted to lowercase and all the punctuations are removed from the words.

Then a dictionary maintaining the count of the words is created named d.

Then it is printed at the end using a for loop.

Code:

filename = input("Enter filename: ")

f = open(filename, 'r')

words = f.read().split(" ")

f.close()

d = {}

for i in range(len(words)):
words[i] = words[i].lower()
  
if(not words[i][-1].isalpha()):
words[i] = words[i][:-1]
  
if words[i] not in d:
d[words[i]] = 1
else:
d[words[i]] = d[words[i]] + 1
  
for k, v in d.items():
print(k, v)
