我刚开始学习Python。我遇到了一个问题。请清除我的疑问。
a='abc'
b='abc'
a==b #When I run this O/P is True. But, in C/C++ or Java it turns out to be False because the variables(a & b) refer to different memories.
a is b #When I run this O/P is True. Ok understood , but.....
但当
a=[1,2,3]
b=[1,2,3]
a==b #The out put is True
a is b #THe output is False
在字符串和列表的情况下，两个不同输出的原因是什么？
