将值分配给Pandas中的多个列 [英] Assign values to multiple columns in Pandas

问题描述

我遵循简单的DataFrame-df:

I have follow simple DataFrame - df:

   0
0  1
1  2
2  3

一旦我尝试创建新列并为其分配一些值，如下所示:

Once I try to create a new columns and assign some values for them, as example below:

df['col2', 'col3'] = [(2,3), (2,3), (2,3)]

我遵循以下结构

   0 (col2, col3)
0  1    (2, 3)
1  2    (2, 3)
2  3    (2, 3)

但是，我正在寻找一种达到此目的的方法:

However, I am looking a way to get as here:

   0 col2, col3
0  1    2,   3
1  2    2,   3
2  3    2,   3

推荐答案

类似的解决方案很简单:

Looks like solution is simple:

df['col2'], df['col3'] = zip(*[(2,3), (2,3), (2,3)])
