Question

5.30 Develop the function many() that takes as input the name of a file in the current directory (as a string) and outputs the number of words of length 1, 2, 3, and 4. Test your function on file sample.txt.

>>> many('sample.txt')

Words of length 1 : 2

Words of length 2 : 5

Words of length 3 : 1

Words of length 4 : 10

Coding language is python

Answer 1

Below is a screen shot of the python program to check indentation. Comments are given on every line explaining the code.

Below is the output of the program:

#CODE STARTS HERE----------------

def many(f_name):
   word_dict = dict() #Dictionary to store the count
   with open(f_name) as f: #open file
      for line in  f.readlines():  #Read line by line
         for word in line.split(): #read word by word
            word_len = len(word)# calculate the length of the word
            if word_len<=4: #If word is less than 4 char long, add it to dict
               #Adds a new word length or updates the existing one
               word_dict[word_len] = word_dict.get(word_len, 0) + 1
   return word_dict #returns the dict


result_dict = many("sample.txt") #Function call
for tup in sorted(result_dict.items()): #Sort the dict and print the result
   print("Words of length",tup[0],":",tup[1])
