使用pip安装了Python软件包，但无法导入使用

Question

Apologies if this is the noobest question in existence, but I think this is an issue with my path? Terminal output below

Vincents-MacBook-Pro:~ vincentlevinger$ pip install binance
Requirement already satisfied: binance in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
Vincents-MacBook-Pro:~ vincentlevinger$ python import binance
/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'import': [Errno 2] No such file or directory
Vincents-MacBook-Pro:~ vincentlevinger$ 

Answer 1

This is not Python:

python import binance

Here, you are trying to invoke the Python interpreter with the python command. But this command does not take Python code as argument, it takes an executable! So you are actually trying to run the import script, which of course, doesn't exist.

If you want to access the Python interpreter without feeding him a script, just run the python command without arguments:

python

It will open the Python interpreter (you can recognise it by its prompt: >>> ). Now you can type Python code:

>>> import binance

Answer 2

To run a Python code from the command line use this syntax:

python -c "import binance"

Option -c accept a string (one string, hence the quotes that combine space-separated words into one parameter) that will be interpreted by python. You can even pass a multiline script:

python -c "
import binance
print(binance.prices())
"
