Update 05-merging-data.md, possible mistake in output directory name

[jarrodscott]

There is no data_output directory nor has this been created at this point (lines 126 & 136) in the lesson. Suggest changing to data :)

Thanks for pointing this out, @jarrodscott.

git log --full-history -p -- data_output

reveals that data_output directory was removed from this repo in 6f05f1c9d51afc44a8151fa824a4eb9ff9a2bdc7. Now, It is mentioned in the first episode:

and we will later create a data_output/ folder when we learn how to export data

What do you think is the best course of action here: update wording in the first episode or add instructions on how to create data_output directory (and, if so should we create a directory in a shell, Jupyter notebook, or using os.mkdir)?

[jarrodscott]

@maxim-belkin of course! It is mentioned on L112 of lesson 00. I am afraid this is my bad. The instructions in the first episode clearly state that we will need to create additional directories (inc. data_output/). Sorry for clogging your bandwidth :)

I think in lesson 5 adding perhaps an instruction like "If you have not already done so, create a new directory called data_output/. Then leave it up to the student on how they wish to create a new directory since there seems to be several options (I am a python newbie, but that is my impression).

[maxim-belkin]

I'd like the lesson to provide all the necessary instructions and/or data (folders). Saving output to the data folder seems fine for the intents and purposes of the lesson, so let's remove the note about the data_output folder and make sure it's not used or mentioned anywhere else.

a gentle ping, @jarrodscott :)
