Dave,
Thanks for your nice explanation. For your answer on one of my questions:
*Modules don't have methods. open is an ordinary function in the module.*
Isn't "method" and "function" used interchangeably? In other words, aren't they
the same thing?
Or, Python has some naming conventions here?
You've already received answers to this, but a short example might clarify the
difference:
#------- Code --------
# Define a function
def func1():
print('This is function func1()')
# Define a class with a method
class Examp:
def func2(self):
print('This is method func2()')
# Try them out
obj = Examp() # Create an object (an instance of class Examp)
func1() # Call the function
obj.func2() # Call the method through the object
func2() # Try to call the method directly -- Error!
#------- /Code --------
This code results in the following:
This is function func1()
This is method func2()
Traceback (most recent call last):
File "fun-meth.py", line 14, in <module>
func2()
NameError: name 'func2' is not defined

You COULD have something like this though:
# --- myModule.py ---
def myFunc():
print 'myFunc'
# --- main.py ---
import myModule
myModule.myFunc()
In this case, myFunc LOOKS like a method when it is called from main.py, but it
is still a function.
My purpose was to give a _simple_ example of the difference in the two terms: that a function
is called directly and a method is called through an object.
Your example may _look_ the same (it uses the same dot syntax), but here it is to resolve a
namespace -- a module is not an object. So yes, this is still a function and not a method. But
we're getting rather pedantic here.
