-  \item \typ{\%save four\_plot.py 16 18-27}
-  \item \typ{\%run -i four\_plot.py}

+  It returns the logs of all commands(including mistakes) used in IPython interpreter.
+  \item \typ{\%hist -n}\\
+It disables the line number representation of logs.
+  \item \typ{\%save four\_plot.py 16 18-27}\\
+For creating a script named four\_plot which includes line 16 and line 18 to 27 of logs.
+  \item \typ{\%run -i four\_plot.py}\\
+Running the python script inside IPython interpreter.
