在Python中打印对象列表时如何应用__str__函数 [英] How to apply __str__ function when printing a list of objects in Python

问题描述

这个交互式python控制台代码片段将告诉一切:

Well this interactive python console snippet will tell everything:

>>> class Test:
...     def __str__(self):
...         return 'asd'
...
>>> t = Test()
>>> print(t)
asd
>>> l = [Test(), Test(), Test()]
>>> print(l)
[__main__.Test instance at 0x00CBC1E8, __main__.Test instance at 0x00CBC260,
 __main__.Test instance at 0x00CBC238]

基本上，我想在打印列表时打印三个asd字符串.我也尝试过pprint，但是它给出了相同的结果.

Basically I would like to get three asd string printed when I print the list. I have also tried pprint but it gives the same results.

推荐答案

尝试:

class Test:
   def __repr__(self):
       return 'asd'
