Hello
Is it possible to count the number of time a function is called ?
Of course, if I've access to the source code, it's easy.
I tried the following :
def foo():
print "foo !"
class wraper(object):
def __init__(self,fun):
globals()[fun]=self.replacement
def replacement(*args):
print "I'm replaced"
foo()
X=wraper(foo)
foo()
I was hoping that globals()[foo] would be replaced by my X.replacement
and thus the second call to foo() was expected to print "I'm replaced".
Instead nothing is done.
By the way, I tried to print globals() inside __init__() to see what
happens. It turns out that the entry 'foo' is never modified.
Any idea ?
I fact what I have to do is to add a decorator _a posteriori_ ...
The keys of globals() are the _names_. You're giving it the function
itself.
Try this:
class wraper(object):
def __init__(self,fun):
globals()[fun.__name__]=self.replacement
def replacement(*args):
print("I'm replaced")
A decorator would be better.
