ipython Notebook Pandas Max允许的列 [英] ipython notebook pandas max allowable columns

问题描述

我有一个简单的csv文件，其中包含十列！

I have a simple csv file with ten columns!

当我在笔记本中设置以下选项并打印我的csv文件(位于pandas数据框中)时，它不会从左到右打印所有列，而是打印前两列，下两列，依此类推上.

When I set the following option in the notebook and print my csv file (which is in a pandas dataframe) it doesn't print all the columns from left to right, it prints the first two, the next two underneath and so on.

我使用了此选项，为什么它不起作用?

I used this option, why isn't it working?

pd.option_context("display.max_rows",1,"display.max_columns",100)

即使这似乎不起作用:

pandas.set_option('display.max_columns', None)

推荐答案

我假设您要在笔记本中显示数据，但以下选项对我来说效果很好(IPython 2.3):

I assume you want to display your data in the notebook than the following options work fine for me (IPython 2.3):

import pandas as pd
from IPython.display import display
data = pd.read_csv('yourdata.txt')

直接设置选项

pd.options.display.max_columns = None
display(data)

或者，使用您显示的set_option方法也可以正常工作

Or, use the set_option method you showed actually works fine as well

pd.set_option('display.max_columns', None)
display(data)

如果您不想为整个脚本设置此选项，请使用上下文管理器

If you don't want to set this options for the whole script use the context manager

with pd.option_context('display.max_columns', None):
    display(data)

如果这没有帮助，您可以举一个最小的例子来重现您的问题.

If this doesn't help, you might give a minimal example to reproduce your issue.
