' inside "

[daviddoria]

I have to call this many times:

MyScript.py --top='?_0.png'

where the 0 should be replaced with 0, 1, 2, 3, etc

I tried this:

for i in {0..3}; do 
echo MyScript.py --top="'?_${i}.png'";
MyScript.py --top="'?_${i}.png'";
done;

It seems to make the command look correct (ie the single quotes are around the filename and the i is expanded properly), but python does not interpret it the same way as if I run the first command on the command line directly.

Any idea why this would be?

Thanks,
Dave
