Module Import: NameError: Name Is Not Defined

How do I define the function in the importer so that it is visible inside imported? I tried this importer.py is def build(): print 'building' build() import imported Whereby

Solution 1:

importer.py

def build():
   print("building")

build() #this extra call will print "building" once more.

imported.py

from importer import build
build()

Note that both importer.py and imported.py must be in same directory. I hope this solve your problem

Solution 2:

Imports are not includes: they are idempotent and should always be at the top of a module.

There is no circularity; once import foo is seen, further instances of import foo will not load the module again.

You are getting the NameError because in the context of imported.py, there is no name build, it is known as importer.build().

I have no idea what you are trying to do with code as oddly structured as that.

Solution 3:

I know that this is a blasphemy but the thing that allows to import a module without tying the imported with importer is easily available in Python as a script language. You can always evaluate a file with execfile
