Python multiple for循环

Question

我想知道以下代码中的3 for循环是否可以用更好的方式编写：

   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

Answer 2

试试这个：）

[(c1, c2, c3) for c1 in cc1 for c2 in cc2 for c3 in cc3]
