Below are the codes I have tried to read the text in the text file in a method called check_keyword()

def check_keyword():

    with open(unknown.txt, "r") as text_file:

        unknown = text_file.readlines()



    return unknown

This is how i called the method:

dataanalysis.category_analysis.check_keyword()

The text in the text file:

Hello this is a new text file

There is no output for the method above :((

If you are returning an open file like that, you're not closing it.

text_file.readlines() returns a list of strings containing the lines in the file. If you want only a string, not a list of the lines, use text_file.read() instead.

You also have another problem in your code, you are trying to open unknown.txt, but you should be trying to open 'unknown.txt' (a string with the file name).

Are you getting any error or just no return value? Also, make sure the file name is correct and the file is not empty.

Instead of text_file.readlines() use text_file.read() which will give you contents of files in string format rather than list.
