Python 多重 for 循环

Question

我想知道是否可以用更好的方式编写以下代码中的 3 个 for 循环:

   Nc = 10     # number of points for (0, pi)
   cc1 = linspace(0,pi,Nc)
   cc2 = linspace(0,pi/2,Nc/2)
   cc3 = linspace(0,pi/2,Nc/2)
   for c1 in cc1:
       for c2 in cc2:
           for c3 in cc3:
               print c1,c2,c3

Answer 1

import itertools

for a,b,c in itertools.product(cc1, cc2, cc3):
    print a,b,c
