Python Text Statistics Calculator (Words, Vowels, Case Count)

Aim: Write a function that reads a file file1 and displays the number of words, number of vowels, blank spaces, lower case letters and uppercase letters

Program:


def count_of_char():
 print("Enter the Name of File:")
 fileName = str(input())
 fileHandle = open("fileName","r")
 tot = 0
 number_of_words=0
 l_c_l=0
 u_c_l=0
 ch=0
# to dispaly file
 data=fileHandle.read()
 print(data)

#to get count of lower and upper case
 for ch in data:
  if (ch.islower()):
   l_c_l+=1
  elif(ch.isupper()):
   u_c_l+=1
  ch=ch.lower()
 print("Lower case letters are :",l_c_l)
 print("Upper case letters are :",u_c_l)

#to get count of blank spaces
 for char in data:
  if char==' ':
     tot = tot+1
  if tot>1:
     print("\nThere are "+ str(tot) + "Blank spaces available in the File")

#to get count of vowels
 vowels = ['a','e','i','o','u','A','E','I','O','U']

 for char in data:
   if char in vowels:
     tot = tot+1

 print("\nTotal Vowels are:")
 print(tot)
#to get count of no of words
 for line in data:
   number _of _words+= len(line. split())
 print("number_ of_ words:")
 print(number_ of_ words)

count_ of_ char()

Output:

Sample Viva Questions and Answers

What is the purpose of the text statistics calculator?
The program calculates various statistics of a given text, including the number of words, vowels, and the count of uppercase and lowercase letters.
What inputs does the text statistics calculator require?
The program requires a string input, which can be provided directly or read from a text file.
How does the program count the number of words in the text?
The program typically splits the text into words using spaces or punctuation as delimiters.
What method is used to count vowels in the text?
The program iterates through each character in the text and checks if it is a vowel (a, e, i, o, u) in both uppercase and lowercase.
How does the program differentiate between uppercase and lowercase letters?
The program checks the ASCII values or uses string methods to determine if a character is uppercase or lowercase.
What will the output of the program include?
The output will display the total number of words, the count of vowels, and the counts of uppercase and lowercase letters.
What is the time complexity of counting words and vowels in the text?
The time complexity is generally O(n), where n is the number of characters in the text, as each character needs to be processed.
How can the program be modified to ignore punctuation when counting words?
By removing punctuation from the text before splitting it into words.
What improvements could be made to the program?
Adding functionality to handle different languages or character sets and providing a user-friendly interface for input.
Can the program handle large texts efficiently?
Yes, with proper implementation, the program can handle large texts, but memory management and optimization techniques may be necessary.
