Question

PYTHON

Make a dictionary with a list inside of it to keep track of word frequency in a text file. example {1:['and','there','we'], 2: ['she','he']}

Answer 1

CODE:

#opening the file
file = open("C:/Users/Win10/Documents/input.txt","r")
#creating a list lines which will contain all the words of the file
lines = []
#dictionary frequency which will the frequency of each word in the file
frequency = {}
#reading the lines in the file
lines = file.readlines()
#splitting the line read into words
lines = lines[0].split()
#iterating through all the words read from the file
for i in lines:
    a = 0
    for j in lines:
        #finding the frequency of each word
        if i == j:
            a += 1
    #adding the word as key and its frequency in a dictionary
    frequency[i] = a
    #removing the word from the list whose frequency was counted just now so that it doesnt gets repeated in the dictionary
    lines.remove(i)

#creating a dictionaty that will hold the word frequency
f = {}
#creating an empty list with the various frequencies as the key
for i in frequency.items():
    f[i[1]] = []
#adding the word of a given frequency to its respective key in the dictionary f
for i in frequency.items():
    f[i[1]].append(i[0])
#printing the key and its list in each line
for i in f:
    print(i," ",f[i])
#printing the dictionary
print(f)
