How to take params for pip from variables? [duplicate]

Question

I want to download files from requirement.txt file, but I need manually edit directory where I need to download them.

For example usual pip download:

!pip download -r C:/Users/Test/requirements.txt -d C:/Users/Test/whldir

But I want put it to function where will be variables for directories:

reqs = C:/Users/Test/requirements.txt
whls = C:/Users/Test/whldir
!pip download -r reqs -d whls

Is this possible to do?

download from a Python script? just use string formatting and subprocess.Popen (or just the latter, it will concatenate it for you), so like subprocess.Popen(["pip", "download", "-r", reqs, "-d", whls]) (not sure about any extra arguments but this should work... I think) — Matiiss

@Matiiss The syntax !pip suggests the environment is Jupyter Notebook; the OP should have mentioned that and used proper tags. — phd

@phd I was wondering what it was for, thanks for explaining... welp, haven't used Jupyter, not sure whether my comment is needed anymore then — Matiiss

pip itself has no such facility, but the environment probably has support for variables of some kind. You seem to be asking about ipython or Jupyter; could you please edit to clarify which tool you are asking about? — tripleee

What is that exclamation mark? What language is it? Looks like shell or windows cmd.

For windows cmd:

set reqs=C:/Users/Test/requirements.txt
set whls=C:/Users/Test/whldir
pip download -r %reqs% -d %whls%

For unix shells:

reqs="/Users/Test/requirements.txt"
whls="/Users/Test/whldir"
pip download -r $reqs -d $whls

"What is that exclamation mark? What language is it?" Python in a Jupyter Notebook. Exclamation mark is used to run shell commands.
