pandas: Is there a max size, max no. of columns, max rows?
提问by doanviettrung
.. and, if so, what are those max limits of pandas?
..而且，如果是这样，熊猫的最大限制是多少？
Sorry, this question seems elementary but I couldn't find an answer at pandas.pydata.org.
抱歉，这个问题看起来很初级，但我在 pandas.pydata.org 上找不到答案。

The limit is your memory. ( but these limits are really large )
极限是你的记忆。（但这些限制真的很大）
But when you want to display a DataFrame table in "Jupyter Notebook", there is some predefined limits.
但是当您想在“Jupyter Notebook”中显示 DataFrame 表时，有一些预定义的限制。
For example you can:
例如，您可以：
print (pd.options.display.max_columns) # <--- this will display your limit
pd.options.display.max_columns = 500 # this will set limit of columns to 500
The same idea work with rows:
同样的想法适用于行：
display.max_rows
