Question

write a program in pythan to enter a paragraph without any punctions assume that the largest word in the prograph is of 10 alphabets the output of the program should count the number of words of different length
print the words of same length in form of list
finally the program should also print total no of words
​

Answer 1

Answer:

Many times it is required to count the occurrence of each word in a text file. To achieve so, we make use of a dictionary object that stores the word as the key and its count as the corresponding value. We iterate through each word in the file and add it to the dictionary with count as 1. If the word is already present in the dictionary we increment its count by 1.

Example #1:

First we create a text file of which we want to count the words. Let this file be sample.txt with the following contents:

Mango banana apple pear

Banana grapes strawberry

Apple pear mango banana

Kiwi apple mango strawberry

Note: Make sure the text file is in same directory as the Python file.

# Open the file in read mode  

text = open("sample.txt", "r")  

 

# Create an empty dictionary  

d = dict()  

 

# Loop through each line of the file  

for line in text:  

   # Remove the leading spaces and newline character  

   line = line.strip()  

 

   # Convert the characters in line to  

   # lowercase to avoid case mismatch  

   line = line.lower()  

 

   # Split the line into words  

   words = line.split(" ")  

 

   # Iterate over each word in line  

   for word in words:  

       # Check if the word is already in dictionary  

       if word in d:  

           # Increment count of word by 1  

           d[word] = d[word] + 1

       else:  

           # Add the word to dictionary with count 1  

           d[word] = 1

 

# Print the contents of dictionary  

for key in list(d.keys()):  

   print(key, ":", d[key])  

Output:
