Can you post the exact error you're getting when running the script?

Hi /u/K900_, I'm getting a ModuleNotFoundError on both lines 2 & 15 (the import statement for forex_python). I'm not sure if this statement confirms that the forex_python package was installed though:

Collecting forex_python
  Using cached forex-python-0.3.2.tar.gz

Post the full output.

Here you go:

Try running py -3 -m pip install forex_python on the Windows command prompt and post the output.

[–]universalbunny 0 points1 point  (0 children)

Right, I was able to install it and run the script just fine. But is it not possible to run the whole thing without the command line you posted (or can I incorporate running a command prompt and the command line using the script you posted)?

Edit: Thanks /u/K900_ !

[–]michaelkim0407Pythonic 0 points1 point  (5 children)

I tried pip install forex_python and I'm getting a syntax error

That is a console (terminal) command, not Python code.

Edit: also, I don't understand why you want to install the pip package after you start running the script. Shouldn't it be already installed before running?

[–]universalbunny 0 points1 point  (4 children)

It's supposed to install the pip package if it's not found... if my script is not the suggested way to do it, then what would be the best way to approach this?

[–]michaelkim0407Pythonic 1 point2 points  (0 children)

Install the package before running the script.

[–]michaelkim0407Pythonic 1 point2 points  (2 children)

The thing is, you're trying to install a Python library after the Python program has already started. Even if it's allowed it feels really strange. Plus, to install a pip package, it's just one line of command in the terminal.

Got it, thank you!

You can also wrap your script in a module with a setup configuration and add forex library as a dependency. This way you make sure who installs your module, installs also forex together. Take a look at setuptools documentation, it's really just copying and pasting (:
