[Python Cookbook] IPython: An Interactive Computing Environment

You can launch IPython on the command line just like launching the regular Python interpreter except with the ipython command:

$ ipython

Then you can execute arbitary Python statements by typing them in and pressing <return>.

If you want to exist, you can use the following command:

exist()

or

exist

Here are some useful tips:

  • While entering expressions in the shell, pressing <Tab> will search the namespace for any variables
  • Using a question mark (?) before or after a variable will display some general information about the object
  • Using ?? will also show the function’s source code
  • A number of characters combined with the wildcard (*) will show all names matching the wildcard expression.
