Python: ogranicz szerokość drukowanych kolumn pand DataFrame

Question

Próbuję wydrukować DataFrame pandy. Jedna z kolumn jest zbyt szeroka (jest to bardzo długi ciąg). Aby wydrukować, używam biblioteki tabulate. Ale po wydrukowaniu pokazuje całą zawartość wszystkich kolumn w jednej bardzo długiej linii. Oto, co widzę:

row name                        review                                                                                                                                                                                                                                                            rating 

0 Planetwise Flannel Wipes                   These flannel wipes are OK, but in my opinion not worth keeping. 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
