Python Read Entire File | read() Method Guide

In Python, readall is not a built-in function or method. It may be a custom function or method in your code. Typically, if you want to read all the contents of a file, you can open the file using the open() function, and then use the read() method to read all the contents, as shown below:

with open('filename.txt', 'r') as file:
    content = file.read()
    print(content)

The above code opens a file named filename.txt in read-only mode. It then uses the read() method to read the file’s content and store it in a variable called content. Finally, it prints the content.
