Ex15 study drills, NameError: name 'read' is not defined

Python
#1

Hi all,

Use only input and try the script that way. Why is one way of getting the filename better than another?

On ex15, study drill 5, I don’t understand what is being asked for. Use only input instead of what?

With number 6, I use open("ex15_sample.txt") and get this:
<_io.TextIOWrapper name='ex15_sample.txt' mode='r' encoding='cp1252'>

Which could be what we expect but I have no idea, the drill doesn’t specify.

When attempting to use read("ex15_sample.txt"), I get:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'read' is not defined

Any help would be appreciated.

Also now that I look at it, the same is true when trying study drill 7 with close()

>>> close("ex15_sample.txt")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'close' is not defined

Yes, that’s a file object: an instance of the class that provides the API for all the I/O operations that deal with files, including read and close. Bind it to a variable, then you can use those operations on it:

file = open("ex15_sample.txt")
text = file.read()
file.close()

You may want to take a look at the I/O documentation.

I think I replied to you offline but I’ll answer here too:

Try skipping this then coming back. I think you’ll get it in a few more exercises.
