Speeding up Python Imports -


i have large program structured using object oriented techniques, , have 1 main driver module imports bunch of other classes, in turn import more python built-in modules or other classes. there on 250 from x import y statements (i don't have control on part of code), duplicates in other classes , unique. profiled code , suspected majority of time in start import many modules , classes. there way speed this?

you can move import statements inside functions reduce initial startup.

another technique copy modules ramdisk or tmpfs faster io (these use ram, runs faster).
