Question

我是一个正在学习熊猫的大人物。我尝试了以下两件事，但没有解决。我使用 Jupyter 笔记本。你能帮我吗？

#1

import sys
sys.getdefaultencoding()

#2

from importlib import reload
import sys
reload(sys)

#我想成功。 #我在另一个文件中成功了，但在当前文件中无法运行。

from pandas import Series,DataFrame
import pandas as pd

data={"ID":["001","002","003"],
      "city":["hyougo","tiba","gihu"],
      "people":["100","230","249"]}
data_frame=DataFrame(data)
print(data_frame)

Answer 1

需要先导入pandas，然后在pd前添加别名DataFrame

import pandas as pd

data={"ID":["001","002","003"],
      "city":["hyougo","tiba","gihu"],
      "people":["100","230","249"]}
data_frame=pd.DataFrame(data)
print(data_frame)

打印：

    ID    city people
0  001  hyougo    100
1  002    tiba    230
2  003    gihu    249

如果你没有安装pandas，你需要先安装

pip install pandas

我在熊猫“DataFrame”的错误中遇到了麻烦
