2 posts were split to a new topic: Why does the code append “Air Buddy” twice?

Aside from code for one sec, is this task a reference to the movie “Air Bud: Golden Receiver” changed slightly to stay safe on the copy-right side of things? :smiley::thinking:
THIS MOVIE
I haven’t watched it myself, just found it while googling (for some reason) to see if Air Buddy was real…:crazy_face:

edit: I watched the trailer, looks super lame. :+1:

why does it print <_io.TextIOWrapper name=‘cool_dogs.txt’ mode=‘a’ encoding=‘UTF-8’> rather than a string

I think the explanation: “using the file object’s .write() method appends whatever is passed to the end of the file in a new line.” is not up to date or just wrong.

They are not directly added in new lines, but in the same line. For accessing new lines you could write for example:

with open('cool_dogs.txt', 'a') as cool_dogs_file:
  cool_dogs_file.write("\nAir Buddy")

The explanation of this lesson kind of confused me:

Where did the extra appended line come from? I thought it was only appended once

This was a popular file......
and it still is...
and it still is

Because they run that line 2 times as I remember.

Oh as in the code below, written twice?

with open('generated_file.txt', 'a') as gen_file:
  gen_file.write("... and it still is")

I thought it meant hitting the ‘run’ button twice
