I want to run IPython from the command line. However, I get a syntax error on the first line, importing pylab with the magic function %pylab is giving a syntax error on the %. The command I am using is simply ipython -i script.py.
Any ideas how to solve this?

The easiest way is to run easy_install ipython[all] as an administrator (start button, type cmd , shift+right click on “cmd.exe” and select “Run as administrator”). This installs the latest stable version of IPython including the main required and optional dependencies.
Magic commands or magic functions are one of the important enhancements that IPython offers compared to the standard Python shell. These magic commands are intended to solve common problems in data analysis using Python. In fact, they control the behaviour of IPython itself.
The “%timeit” is a line magic command in which the code consists of a single line or should be written in the same line for measuring the execution time. In the “%timeit” command, the particular code is specified after the “%timeit” is separated by a space.
You need to name your file script.ipy. When it ends in .ipy it can contain ipython syntax.
From ipython --help:
Usage
ipython [subcommand] [options] [files]
If invoked with no options, it executes all the files listed in sequence
and exits, use -i to enter interactive mode after running the files. Files
ending in .py will be treated as normal Python, but files ending in .ipy
can contain special IPython syntax (magic commands, shell expansions, etc.)
