Two Classes In Two Files

[dhable@gmail.com]

I just started working with Python and ran into an annoyance. Is there
a way to avoid having to use the "from xxx import yyy" syntax from
files in the same directory? I'm sure it's been asked a million times,
but I can't seem to find the answer.

For example, I have two classes stored in separate files as such.

File: one.py
========
class One:
def methodA(self):
print "class One"
def methodB(self):
print "class One"


File two.py
========
from one import One

class Two(One):
def methodA(self):
print "class Two"

if __name__ == "__main__":
x = Two()
x.methodA()
x.methodB()

When I run the Two.py file, I get the expected output but I'd like to
eliminate the from line in two.py.

Probably none that are better.

1:
import one
class Two(one.One)

2:
put both classes in the same file.


It's just the way it is. Why worry about it?

You can just use:
import xxx

and then:
class Two(xxx.One):
...

If you don't want to use the import line, you have to put the two
classes into the same module.

Wasn't so much a worry, just trying to figure out how to think the
python way.

Seems like you're thinking the Java way... if you don't want to do it,
put both classes in the same file.

Yes, I have been ruined for the last 5 years with Java and C#. Perl was
my only salvation, but now I can't read the programs I wrote.

ROFL! That's got to be a contender for Quote of the week.

Re: Two Classes In Two Files

Perhaps __init__.py has what you're looking for?

OP: think of a .py file as being more akin to Java package than a .java
file. Don't worry about the resulting files getting too large -- Python
is a lot more compact than Java.
