Write a Python program to count all the line having a as first character || Count number of lines in Python - Creation Code

Why counting the number of lines is important?

Counting the number of characters is important because almost all the text boxes that rely on user input have a certain limit on the number of characters that can be inserted. For example, the character limit on a Facebook post is 63,206 characters. Whereas, for a tweet on Twitter the character limit is 140 characters and the character limit is 80 per post for Snapchat. We will make a change on this process we will just count the number of lines that have 'a' as the first character.

Approach:

• Open the file in reading mode and assign a file object named 'file'
• Assign 0 to the counter variable
• Read the content of the file using the read function and assign it to a variable named 'content'
• Create a list of the content where the elements is split wherever they encounter an '\n'

Implement:

Suppose here we create a file called creationcode.txt and we need to read this file

Code:

#opening the file in read mode

file = open("creationcode.txt",'r')

#creating a variable for counting the number of lines

counter = 0

#reading the file

content = file.read()

#split the line to convert every line into an array

list = content.split("\n")

for i in list:

    if i[0] == 'a':

        counter += 1

print("This is the number of lines having a as first character")

print(counter)

Output:

This is the number of lines having a as first character
