[Numpy-discussion] Slight inconsistency between 'f' shape () array and python scalar

[Rob W. W. Hooft]

Hm. I found a bug in one of my programs that was due to the difference in
behavior between a 'f' shape () array and a true python scalar:

import Numeric
a=Numeric.zeros((50,50),'f')
b=[]
for i in range(50):
    d=a[i,i]
    b.append(d)
nb=Numeric.array(b)
print nb.shape # Expect (50,) but get (50,1)


BTW: Why does "a=Numeric.zeros((50,),'f'); d=a[i]" return a python scalar, and 
the above script a shape () array?
