In a python terminal, simply type the following:
Assuming this works, you should receive no error messages. If the module is not available then you’ll need to have a look here.
The docs for numpy can be found here.
First time you’ve imported a module?
Modules are what make Python great - and there are plenty of them freely available. If ever there is something you think you need to code up from scratch, first have a look around to see if someone has already made a module that covers it - this saves you reinventing the wheel - you may be surprised to find that many of the things you’ll want to do have already been worked out!
Getting help on functions and modules
Each module available in python contains a variety of components including various functions. To see what is available within a given module, documentation can easily be found online - it is also possible to find a list of functions whilst you are on the Python command line. For example:
Following your initial statement -
import numpy - now type
numpy. and hit the tab key…
This will print out a list of the functions available within the numpy module. If there is a function you want to know more about, simply type
numpy.function? and the documentation will appear within your current terminal, usually offering a number of examples as how to make use of the function in question.
