Module Search Path

Describing the Module Search Path

• When loading modules, the interpreter searches the list of directories in sys.path
• The first entry in sys.path is typically an emptry string ''
• This refers to the current working directory

• Other entries in sys.path may consist of:

  • Directory names
  • Zip files
  • Archive files
  • etc.
• Suppose we created two modules foo.py and bar.py
• Then, we placed them in a zip file called modules.zip
• The file could be added to the Python search path:

>>> import sys
>>> sys.path.append('modules.zip')
>>> import foo, bar
