Question

这是我写的以熊猫开头的非常简单的代码。

import pandas
lst = [1,2,3,1,2,3]
lst2 = [5,6,7,5,6,7]
lst3 = [1,2,3,10,20,30] 
s = pandas.Series(lst,lst2,lst3)

输出给出错误：datatype not understood。为什么会这样，我该如何解决？

Answer 1

使用 numpy 连接。如果数字需要唯一，请使用 set

<body>
  <div class="content">
    <div class="panel">
      <div class="description">
        <h1>I dream about this girl everyday, but cannot seem to forget her.</h1>
        <p>People say not many people can fall in love, and it's good I can experience it, but what is unrequited love worth actually.</p>
      </div>
    </div>
    <div class="panel">
      <img src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/210284/original-image.jpg" alt="Original">

    </div>
    <div class="panel">
      <div class="description">
        <h1>My name is John Snow.</h1>
        <p>I like making popcorn with icicles alot.</p>
      </div>
    </div>
  </div>
  <div class="handle"></div>
  </div>
</body>

输出：

lst = [1,2,3,1,2,3]
lst2 = [5,6,7,5,6,7]
lst3 = [1,2,3,10,20,30]

result=np.concatenate([lst,lst2,lst3],axis=0)
print(result)

Answer 2

创建熊猫系列对象的最简单方法是在尝试时使用列表：

import pandas as pd
lst = [1,2,3,1,2,3]
lst2 = [5,6,7,5,6,7]
lst3 = [1,2,3,10,20,30]
#But pandas series object accept only one argument for data. there are others like #index,name, etc
pd.Series(lst + lst2 + lst3)
#creates a series 
0      1
1      2
2      3
3      1
4      2
5      3
6      5
7      6
8      7
9      5
10     6
11     7
12     1
13     2
14     3
15    10
16    20
17    30

将多个列表传递给pandas.Series
