What is the best aproach when it comes to import??, is allways better to
make all the import calls in the global scope, making the overall
runtime of the program better because the program is not going to import
something everytime a function is called, or is better to make specific
import's inside a function making the function completely portable??
here's a example:
case 1:
# importing in the global scope
import foo
variable = "somethin here"
def bar(value1, value2):
return value1, value2 = foo.foo
Case 2:
# importing inside a function
variable = "somethin here"
def bar(value1, value2):
import foo
return value1, value2 = foo.foo
and another thing, making specific import, makes the program less, how
you said this "RAM eater" (sorry my native language is spanish and i
dont now how to translate "cosume menos recursos" google says "cosumes
less resources", but anyway i hope you get it)
I say this because, for example when i'm in the interactive shell and
import big things like Scipy, and NumPy, python takes 3 to 5 seconds to
respond, and if am only going to use like 4 or 5 function inside NumPy i
think is better to say just "from Numpy import foo, bar, qux etc" but i
would actually like to read this from someone that knows about
programming and not just me making asumptions...
salu2!
