Importing modules

The steps to load some of the important modules are as follows:

• To load NumPy and matplotlib to work interactively, along with inline graphics, run the following command:

  pylab inline
  

• To load NumPy and matplotlib without importing names into the current namespace, with inline graphics, run the following command line:

  pylab -–no-import-all inline
  

• To load SciPy modules, use any of the following standard Python import commands:

  import scipy.<module>
  import scipy.<module> as <local-name>
  from scipy.<module> import <function>
  

If the –no-import-all options is used, the functions and objects have to be prefixed by the appropriate module name as follows:

• For NumPy functions and objects, use numpy or np.
• For interactive graphics, use pyplot or plt.

Modules from libraries installed in the system as well as the user-created modules with the.py extension can be imported through the standard Python mechanism.
