【问题描述】：

我正在尝试打印熊猫数据框。其中一列太宽（它是一个很长的字符串）。要打印，我使用tabulate 库。但是当它被打印出来时，它会在一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，这条线太长了。如何限制打印字符串中的字符数？例如，我希望将第 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。

【解决方案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  \

请参阅options docs。

谢谢安迪，我尝试将这些选项与tabulate 一起使用，但它们不起作用。如果我想在一行中查看所有列，但只需键入 df（不使用表格）就可以截断行，那么我需要执行以下操作： pd.options.display.width = 200 pd.options.display.max_colwidth = 50
最大宽度非常大，如果我理解你的话，说 500。那将把它们放在同一行。

【解决方案2】：

试试这个：

pd.options.display.width = 1200
pd.options.display.max_colwidth = 100
pd.options.display.max_columns = 100

【解决方案3】：

你可以这样做：

df['column_name'] = df['column_name'].str[:width]
