Is there a way to read a .txt file and store each line to memory?

Question

I am making a little program that will read and display text from a document. I have got a test file which looks like this:

12,12,12
12,31,12
1,5,3
...

Thanks for @PePr excellent solution. In addition, you can try to print the .txt file with the built-in method String.join(data). For example:

with open(filename) as f:
    data = f.readlines()
print(''.join(data))
