Working with the file system is a common operation in programming languages.
For one reason or another, you'll want to know how to read files from the file system.
In this post, we'll learn how to read a file from the file system using Python.
To start reading a file, you'll want to use the built-in
This function takes in the path to the file you want to read and the mode that you want to open the file in.
Since we are reading a file, we'll want to open it in
Let's see an example of reading a file:
path = 'text.txt' file = open(path, 'r')
From here, you now have an open file that you can interact with.
You can read the entire file in to a single variable using the
path = 'text.txt' file = open(path, 'r') text = file.read() print(text)
You can also read the file line by line if you combine it with a
path = 'text.txt' file = open(path, 'r') while True: line = file.readline() if not line: break print(line)
After you are done using the file, don't forget to close the file to release it back to the operating system.
In this post, we learned how to read a file from the file system using Python.
You can either read the entire file in to a single variable or you can read the file line by line.
