Read data_file.txt?

To read the contents of data_file.txt, you can use the following Python code:

with open('data_file.txt', 'rt') as file:
    data = file.read()
    print(data)

This code opens data_file.txt in read mode, reads all its contents, and prints them to the console. If you need to read it line by line, you can do this:

with open('data_file.txt', 'rt') as file:
    for line in file:
        print(line.strip())  # .strip() removes any leading/trailing whitespace
