相当于R's View for Python's pandas [英] equivalent of R's View for Python's pandas

问题描述

View是一项非常有用的功能，可让我查看R中大型数据框的横截面.

The View is a very useful function to allow me to see cross-section of large data frames in R.

对于Python的熊猫DataFrame，R的View函数是否等效?

Is there any equivalent of R's View function for Python's pandas DataFrame?

对于R，我使用RStudio，对于Python使用PyCharm.

I use RStudio for R and PyCharm for Python.

推荐答案

一个更快的选择可能是设置pandas数据框，以免通过以下代码行换行:

A quicker option might be to set the pandas dataframe so it doesn't line wrap by putting this line of code:

import pandas
pandas.set_option('expand_frame_repr', False)

我正在使用Sublime Text 2，这是它的外观:

I'm using Sublime Text 2 and this is how it looks:

放入选项之前(请注意输出如何环绕文字)

Before putting in option (Notice how the output wraps the text around)

放入选项后(注意输出如何继续)

After putting in option (Notice how the output continues)

还请确保未选中查看">自动换行".

Also make sure that 'View' > 'Word Wrap' is not checked.

另外，您可以通过使用 head(#)这样根据需要打印更多或更少的内容:

Additionally, you can print out more or less as you need by using head(#) like this:

mydf = pandas.DataFrame.from_csv('myfile.csv', header=1)
print mydf.head(20) # Prints first 20 lines

还有其他一些熊猫选项:

Here's some other pandas options:

pandas.set_option('display.max_columns', 0) # Display any number of columns
pandas.set_option('display.max_rows', 0) # Display any number of rows
