How do you read the last 5 lines of a text file in Python?
As we know, Python provides multiple in-built features and modules for handling files. Let's discuss different ways to read last N lines of a file using Python. In this approach, the idea is to use a negative iterator with the readlines() function to read all the lines requested by the user from the end of file.
How do you print the last two lines of a file in Python?
You could use next() on the file object iterator to get the first 2 lines, then use a deque() as a circular buffer to capture the last 2 lines. This will work with files that are less than 4 lines or no lines also!
How do I read a file until the last line in Python?
The readlines () method is the most popular method for reading all the lines of the file at once. This method reads the file until EOF (End of file), which means it reads from the first line until the last line. When you apply this method on a file to read its lines, it returns a list.
