Is there a convention to be considered for deciding if import
statements should be included in a function body? For example, which
of these two module layouts would be preferable:
# --- MyModule1.py -----
import foo1, foo2, foo3
import foo_special
# several coherent functions here
def specialFunction():
doSomethingSpecial()
or the "embedded import" version:
# --- MyModule2.py -----
import foo1, foo2, foo3
import foo_rare
# several coherent functions here
def specialFunction():
import foo_special
doSomethingSpecial()
Also, does the choice have any impact on performance/space/etc.? And
will the import function get called each time (and possibly ignored)
in the second version?
The reason I consider the second form is that the module foo_special
is only used by the code in specialFunction(), and detracts (IMHO)
from understanding the rest of the code in the module.
Thanks,
Marcus
