name 'pd' is not defined

This error occurs when you are trying to use the variable or module 'pd' but it has not been defined or imported in your code.

To fix this error, you need to import the required module. In this case, 'pd' most likely refers to the pandas library, which can be imported using:

import pandas as pd

Once you have imported pandas, you can use its functions and attributes by prefixing them with 'pd.' as shown below:

df = pd.DataFrame(data)

Make sure that you have installed pandas library in your system.

NameError: name 'pd' is not defined

这个错误通常表示你正在使用 pandas 库中的某个函数，但是你没有正确地导入该库。请确保你在代码的顶部导入了 pandas 库：

import pandas as pd

如果你已经导入了 pandas 库，那么可能是因为你的代码中有语法错误，导致 pandas 库没有被正确地加载。请检查你的代码，确保它没有语法错误，并且正确地使用了 pandas 库中的函数。

ipynb name 'pd' is not defined

It seems like you are encountering an error in your Jupyter Notebook. The error message "name 'pd' is not defined" suggests that the variable 'pd' is not recognized or imported.

To resolve this issue, you need to import the necessary library before using it. In this case, it appears that you are trying to use the 'pd' alias for the pandas library.

You can import pandas by adding the following line at the beginning of your code:

import pandas as pd

By importing pandas this way, you can use the 'pd' alias to access pandas functions and classes throughout your code.
