I am just trying to wrap my head around decorators in Python, and I'm
confused about some behavior I'm seeing. Run the code below (slightly
adapted from a Bruce Eckel article), and I get the following output:
inside myDecorator.__init__()
inside aFunction()
Finished decorating aFunction()
inside myDecorator.__call__()
My question: Why isn't the first print statement in "__main__" the
first line of code executed? Is aFunction() not closed somehow?
#!/usr/bin/env python
class myDecorator(object):
def __init__(self, f):
print "inside myDecorator.__init__()"
f() # Prove that function definition has completed
def __call__(self):
print "inside myDecorator.__call__()"
@myDecorator
def aFunction():
print "inside aFunction()"
if __name__ == '__main__':
print "Finished decorating aFunction()"
aFunction()
