Python:限制pandas DataFrame打印列的宽度

Question

我正在尝试打印 pandas DataFrame。其中一列太宽(它是一个很长的字符串)。要打印，我正在使用 tabulate 库。但是当它被打印时，它会在很长的一行中显示所有列的全部内容。这是我看到的:

row  name                                                                                                review                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                rating

I also ordered someImse Vimse Cloth Wipes-Ocean Blue-12 countwhich are larger, had a nicer, softer texture and just seemed higher quality.  I use cloth wipes for hands and faces and have been usingThirsties 6 Pack Fab Wipes, Boyfor about 8 months now and need to replace them because they are starting to get rough and have had stink issues for a while that stripping no longer handles.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  3

3  Stop Pacifier Sucking without tears with Thumbuddy To Love\'s Binky Fairy Puppet and Adorable Book  This is a product well worth the purchase.  I have not found anything else like this, and it is a positive, ingenious approach to losing the binky.  What I love most about this product is how much ownership my daughter has in getting rid of the binky.  She is so proud of herself, and loves her little fairy.  I love the artwork, the chart in the back, and the clever approach of this tool.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                5

如您所见，该行太长了。如何限制打印字符串中的字符数？例如，我希望第 3 行打印成这样:

3  Stop Pacifier Sucking without tears ...    This is a product well worth ...     5 

我希望将此限制应用于表格中的所有行。

Answer 1

有 max_colwidth 和(终端)width:

In [11]: pd.options.display.width = 50

In [12]: pd.options.display.max_colwidth = 50

In [13]: df
Out[13]:
                                                   0  \
