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.
