Question - Write a Python Program to count the number of characters in a text file

Logic and Explanation

Question - Write a Python Program to count the number of characters in a text file

Python Program to count the number of characters in a text file - In this program we have to count the number of characters in a text file so for this first open the required text file in read mode in our python file. 

For this we have to write the below command. Here, the name of text file is "content.txt" and it is present in the same directory where this python file is present, so we just written "content.txt" otherwise you have to write the complete path of the file here.

f = open("content.txt","r")

Now, we will read the content of the file using the read command and will get the data or the text present in it in the form of a string and then we will count of character in this string.

data = f.read()

This data variable is string that contains all the data present in the text file "content.txt". Now, for counting the number of character let's create a variable char_count and initialize it to zero.

char_count = 0

Now for counting the number of characters present in a string we will iterate through all the characters of data string and add one to our char_count. In this way, when we iterate through all the characters the value of char_count variable will be equal to the number of charaters present in file.

Here's the code for the same.

for char in data:
    char_count += 1

print(char_count)

Now, here we iterated and then added one for each character in the string. One direct approach can be just finding the length of string. Length of string data will be equal to the number of characters present in the string.

print(len(data))
