Let us look at the commands that we have typed in. The -history can be retreived by using =%hist= command. Type -:: - - %hist - -As you can see, it displays a list of recent commands that we typed. Every -command has a number in front, to specify in which order and when it was typed. - -Please note that there is a % sign before the hist command. This implies that -%hist is a command that is specific to IPython and not available in the vannila -Python interpreter. These type of commands are called as magic commands. - -Also note that, the =%hist= itself is a command and is displayed as the most -recent command. We should not that anything we type in is stored as history, -irrespective of whether it is command or an error or IPython magic command. - -If we want only the recent 5 commands to be displayed, we pass the number as an argument -to =%hist= command. Hence -:: - - %hist 5 - -displays the recent 5 commands, inclusive of the =%hist= command. -The default number is 40. - -{{{ Pause here and try out the following exercises }}} - -%% 1 %% Read through the documentation of %hist and find out how to - list all the commands between 5 and 10 - -{{{ continue from paused state }}} - -As we can see from =%hist= documentation, -:: - - %hist 5 10 - -displays the commands from 5 to 10 - -Now that we have the history, we would like to save the required line of code -from history.

But second command is a command that gave us an -error. Hence we do not need second command. The commands from third to sixth are -required. The seventh command although is correct, we do not need it since we -are setting the title correctly in the eigthth command. - -So we need first third to sixth and the eigthth command for our program. -Hence the syntax of =%save= is -:: - - %save /home/fossee/plot_script.py 1 3-6 8 - -{{{ point to the output of the command }}} - -The command saves first and then third to sixth and eighth lines of code into -the specified file. - -The first argument to %save is the path of file to save the commands and the -arguments there after are the commands to be saved in the given order. - -{{{ goto the file and open it and show it }}} - -{{{ Pause here and try out the following exercises }}} - -%% 2 %% Change the label on y-axis to "y" and save the lines of code - accordingly - -{{{ continue from paused state }}} - -we use the command =ylabel= on interpreter as -:: - - ylabel("y") - -and then do -:: - - %save /home/fossee/example_plot.py 1 3-6 10 - -Now that we have the required lines of code in a file, let us learn how to run -the file as a python script. - -We use the IPython magic command =%run= to do this.
