Hello,
I must be missing something minor but I just can't figure it out. I
am trying to replace a method in a class with a cdef function defined
in cython, but keep getting the error:
TypeError: function takes exactly 2 arguments (1 given)
I include an example to reproduce the issue, with the .py file and
the .pyx file, below. Any help would be great!
thanks,
Brian Blais
testit.py
=========
class mything(object):
def __init__(self,N):
self.N=N
def doit(self,x):
val=0
for i in range(self.N,x):
val+=i
return val
try:
import c_testit
mything.doit=c_testit.doit
print "Using cython version"
except ImportError:
pass
if __name__=="__main__":
a=mything(10)
print a.doit(50)
c_testit.pyx
============
cpdef doit(object self,int x):
cdef int i
cdef int N=self.N
cdef int val
val=0
for i from N<=i<x:
val+=i
return val
