How to pass a variable to magic ´run´ function in IPython
IPython expands variables with $name
, bash-style. This is true for all magics, not just %run
.
So you would do:
In [1]: filename = "myscript.py"
In [2]: %run $filename
['myscript.py']
myscript.py contains:
import sys
print(sys.argv)
Via Python's fancy string formatting, you can even put expressions inside {}
:
In [3]: args = ["arg1", "arg2"]
In [4]: %run $filename {args[0]} {args[1][-2:]}
['myscript.py', 'arg1', 'g2']
Use get_ipython()
to get a reference to the current InteractiveShell, then call the magic()
method:
In [1]: ipy = get_ipython()
In [2]: ipy.magic("run foo.py")
ERROR: File `u'foo.py'` not found.
Edit See minrk's answer — that's a much better way to do it.
