integrate does not work anymore

[Doerte]

Hello,

some time ago I implemented a Python script, which uses integrate.quad
(...). This was done with Python 2.4 / Win2000.

I'm working with Python 2.5 now, and installed Numpy, Scipy and
Matplotlib. My script and also the test described below do not work
anymore:

from pylab import *
from numpy import *
from scipy import *
from math import *

m = 5
n = 3
f = lambda x:m*x+n
x0 = 2.0
x1 = 6.5
res = integrate.quad(func=f, a=x0, b=x1)

Traceback (most recent call last):

File "<pyshell#15>", line 1, in <module>
res = integrate.quad(func=f, a=x0, b=x1)
NameError: name 'integrate' is not defined


What's wrong here?

Regards,

Doerte

from pylab import *
from numpy import *
from scipy import *
from math import *

Don't do this, read the style guide on writing Python code.

res = integrate.quad(func=f, a=x0, b=x1) [...]
NameError: name 'integrate' is not defined

# try this instead
from scipy import integrate


Note that this is also mentioned on the scipy homepage in their script,
though they also commit the sin of namespace pollution by importing with
wildcards.
