The readlines() Method is very useful for reading files that contain lots of information or have many lines of text. You can also use the readlines() Method to read a file one line at a time, which is great for file-processing tasks. What’s even better is that the readlines() Method is easy to use and can be implemented in just a few lines of code. So if you’re looking for a reliable way to read files in Python, look no further than the readlines() Method!
Syntax:
The readlines() method uses the following syntax:
The readlines() method reads all the lines of the file and returns them as a list of strings, with each string representing a line in the file. The newline character at the end of each line is included in the string.
Example:
Let’s understand the Python’s readlines() method with a few examples. Consider the following file myfile.txt:
To read all the lines of this file using the readlines() method, you can do the following:
This will print the following output:
As you can see, the readlines() method returns a list of strings, with each string representing a line in the file and the newline character at the end of each line included in the string.
You can also use the readlines() method to read a specific number of bytes from the file, as shown in the following example:
This will print the following output:
As you can see, the readlines() method reads the specified number of byes from the file and returns them as a list of strings.
The readlines() method is generally slower than using the for loop and the readlines() method to read the lines of a file, as it reads all the lines of the file into memory at once. However, it is more convenient to use and can be useful when you want to read all the lines of a file in a single call.
