Thanks for the alternative links, I'll use gmane.org as an access point next time.

Does something like
def phi_m(x, m):
rtn = []
for n2 in range(0, len(x) * m - 2):
n = n2 / m
r = n2 - n * m
rtn.append(m * x[n] + r * (x[n + 1] - x[n]))
print ('n2 =', n2, ': n =', n, ' r =' , r, ' rtn =', rtn)
return rtn
look right?
It doesn't seem to have any errors. However, I do receive the following error when trying to implement an x after having defined phi:
>>> x = [0, 1, 1, 2, 3]
>>> phi_m(x, 2)
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
phi_m(x, 2)
File "<pyshell#2>", line 6, in phi_m
rtn.append(m * x[n] + r * (x[n + 1] - x[n]))
TypeError: list indices must be integers, not float
