Can I access python variables within a `%

Question

Is there a way to access variables in the current python kernel from within a %%bash or other %%script cell?

Perhaps as command line argume

Answer 1

One problem is, if the variable that you want to give to your bash is a list, it does not work as expected.

For example, in one python cell:

l = ['A', 'B', 'C']

then if you give it directly to the magic option the next cell:

%%bash -s "$l"
for i in $1
do
echo $i
done

It will be oddly split like this:

['A',
'B',
'C']

The simplest answer is to put code inside braces {} to transform your python list in bash list, like the following:

%%bash -s "{" ".join(l)}"
for i in $1
do
echo $i
done

Which give the expected output:

A
B
C
