[Numpy-discussion] Conversion from numarray to numpy

Some time ago I wrote small lib for signal processing. Now I'm trying to
convert it from numarray to numpy, and I've problem:

Code in numarray:

for  i in range(len(myinput)-m+1):
	cin=tempmatr[:]
	ctmp=tempmatr[i]
	xtmp=(numarray.abs(cin-ctmp))<=r
	x2tmp=numarray.sum(numarray.transpose(xtmp))
	mcount=numarray.sum(x2tmp==m)
	allcount=allcount+mcount

Code in numpy:

for  i in range(len(myinput)-m+1):
	cin=tempmatr[:]
	ctmp=tempmatr[i]
	xtmp=(numpy.abs(cin-ctmp))<=r
	x2tmp=numpy.sum(numpy.transpose(xtmp))
	mcount=numpy.sum(x2tmp==m)
	allcount=allcount+mcount


In numarray line:

xtmp=(numarray.abs(cin-ctmp))<=r

returns array of ones and zeros, but in numpy

xtmp=(numpy.abs(cin-ctmp))<=r

returns True/False


I would like to know how change this True/False to 1/0
