Python with matplotlib - drawing multiple figures in parallel

I have functions that contribute to small parts of a figure generation. I'm trying to use these functions to generate multiple figures? So something like this:

1. work with Figure 1
2. do something else
3. work with Figure 2
4. do something else
5. work with Figure 1
6. do something else
7. work with Figure 2

If anyone could help, that'd be great!
