How can you read a text file line by line in Python and process each line separately?
In Python, you can read a text file line by line using a simple loop and process each line separately. The most common way to achieve this is by using the open()
function to open the file, and then using a for
loop to iterate over the lines.

Here's a step-by-step guide:
- First, you need to open the text file using the
open()
function. You can specify the file path and mode (read, write, append, etc.). For reading, use the mode'r'
. - Use a
for
loop to iterate over the file object. This will automatically read the file line by line. - Inside the loop, you can process each line as needed, such as printing it, performing some calculations, or storing it in a list, etc.
- Finally, don’t forget to close the file using the
close()
method to release the resources.
Here’s an example demonstrating how to read a text file line by line and process each line separately:
file_path = 'path/to/your/textfile.txt'
try:
with open(file_path, 'r') as file:
for line in file:
# Process each line separately, for example, printing it:
print(line.strip()) # .strip() removes the newline character at the end of each line
