Text File Handling Practice Questions

  1. Write a function, vowelCount() in Python that counts and displays the number of vowels in the text file named Poem.txt.
    def vowelCount():
      f = open("Poem.txt", "r")
      count = 0
      s = f.read( )
      for i in s:
            if i in 'AEIOUaeiou':
                  count = count + 1
      print("Number of vowels = ", count)
      f.close()

vowelCount()
  2. Write a function in Python to read a text file, Alpha.txt and displays those lines which begin with the word 'You'.
    def youLines():
      f = open("Alpha.txt", "r")
      count = 0
      L = f.readlines()   #[ "line1", "line2", .......]
      for line in L:
            words = line.split()  #["word1", "word2", .......]
            if words[0] in ["you", "You", "YOU"]:
                  print(line)
      f.close()

youLines()
  3. Write a function ETCount() in Python, which should read each character of a text file “TESTFILE.TXT” and then count and display the count of occurrence of alphabets E and T individually (including small cases e and t too). 
    
Example:
If the file content is as follows:
Today is a pleasant day.
It might rain today.
It is mentioned on weather sites

The ETCount() function should display the output as:
E or e: 6
T or t : 9
    def ETCount():
      f = open("Testfile.txt", "r")
      count_E = 0
      count_T = 0
      s = f.read()
      for i in s:
            if i == 'E' or i == 'e':
                  count_E +=1
            elif i == 'T' or i == 't':
                  count_T +=1
      print("E or e : ", count_E)
      print("T or t : ", count_T)
      f.close()

ETCount()
  4. Write a method COUNTLINES() in Python to read lines from text file ‘TESTFILE.TXT’ and display the lines which are not starting with any vowel. 
    
Example: 
If the file content is as follows:
An apple a day keeps the doctor away.
We all pray for everyone’s safety.
A marked difference will come in our country.

The COUNTLINES() function should display the output as:
The number of lines not starting with any vowel - 1
    def COUNTLINES():
      f = open("TESTFILE.txt", "r")
      count = 0
      L = f.readlines()   #['line1', 'line2', ......]
      for line in L:
            if line[0] not in "AEIOUaeiou":
                  count += 1
      print("Number of lines not starting with any vowel - ", count)
      f.close()

COUNTLINES()
  5. Write a function in Python that counts the number of “Me” or “My” words present in a text file “STORY.TXT”. 
    
Example : 
If the “STORY.TXT” contents are as follows:
My first book was Me and My Family. 
It gave me chance to be Known to the world.

The output of the function should be:
Count of Me/My in file: 4
    def countMeMy():
      f = open("STORY.txt", "r")
      count = 0
      s=f.read()
      wordlist = s.split()    #[ 'word1', 'word2', ......]
      for word in wordlist:
            if word in [ 'Me', 'me', 'ME', 'mE', 'My', 'my', 'MY', 'mY' ]:
                  count = count + 1
      print("Count of Me/My in file : ", count)
      f.close()

countMeMy()
  6. Write a method/function DISPLAYWORDS() in python to read lines from a text file STORY.TXT, and display those words, which are less than 4 characters.
    def DISPLAYWORDS():
      f = open("Story.txt", "r")
      s=f.read()
      wordlist = s.split()     #['word1', 'word2', ....]
      for word in wordlist:
            if len(word) < 4:
                  print(word)
      f.close()

DISPLAYWORDS()
  7. Write a function in python to count the number of lines in a text file ‘STORY.TXT’ which is starting with an alphabet ‘A’ .
    def A_lines():
      f = open("story.txt", "r")
      count = 0
      lineslist = f.readlines()    #['line1', 'line2', ....]
      for line in lineslist:
            if line[0] == 'A' or line[0] == 'a' :
                  count = count + 1
      print("No. of lines starting with A = ", count)
      f.close()

A_lines()
