Why it's a convention to import pandas as pd?
提问by Juan
I see that in the pandas documentation they recommend importing pandas as:
我在Pandas文档中看到他们建议将Pandas导入为：
import pandas as pd
I can see some sense in doing that for when you are using pandas in an interactive context (as with a ipython/jupyter notebook), but I've seen it in production code and in widespread libraries (like Bokeh: https://github.com/bokeh/bokeh/search?p=2&q=pd&type=Code&utf8=%E2%9C%93). Is there a reason for that apart from convention?
当您在交互式上下文中使用 Pandas（如 ipython/jupyter 笔记本）时，我可以看到这样做的意义，但我已经在生产代码和广泛使用的库中看到了它（如 Bokeh：https://github .com/bokeh/bokeh/search?p=2&q=pd&type=Code&utf8=%E2%9C%93）。除了约定之外还有其他原因吗？

Because there are built-inmethods in python which overlap with the pandas methods. Like map(), all(), any(), filter(), max(), min()and many others. In order to avoid the confusion that these methods used are from pandas or built-in. It is always better to import pandas as import pandas as pdand call the pandas methods using the pdprefix.
因为built-inpython中有一些方法与pandas方法重叠。像map(), all(), any(), filter(), max(), min()和许多其他人一样。为了避免混淆使用的这些方法是来自pandas还是内置的。导入 pandas asimport pandas as pd并使用pd前缀调用 pandas 方法总是更好。
There might be other libraries which have the same method names, so to avoid overridingwe use the prefix part.
可能还有其他库具有相同的方法名称，因此为了避免overriding使用前缀部分。
