Python:打印所有命名元组

Question

我有以下代码:

from collections import namedtuple

Test = namedtuple('Test', ['number_A', 'number_B'])

test_1 = Test(number_A=1, number_B=2)
test_2 = Test(number_A=3, number_B=4)
test_3 = Test(number_A=5, number_B=6)

我的问题是如何打印所有命名元组，例如:

print (Test.number_A)

我希望看到这样的结果:

1
3
5

有什么想法吗？ 谢谢..

Martijn Peters 在评论中提出建议:

Do not use numbered variables. Use a list to store all the named tuples instead. Simply loop over the list to print all contained named tuples.

这是它的样子:

Test = namedtuple('Test', ['number_A', 'number_B'])
tests = []
tests.append(Test(number_A=1, number_B=2))
tests.append(Test(number_A=3, number_B=4))
tests.append(Test(number_A=5, number_B=6))

for test in tests:
    print test.number_A

给予:

1
3
5
