有没有办法在不等待用户输入的情况下打印 python 数据表

Question

I am printing a python datatable Frame. It pages when I do that, it's waiting for my input at the end, even for very small Frames. For example,

In [12]: DT = dt.Frame(A=range(5))

In [13]: DT
      A
---  --
 0    0
 1    1
 2    2
 3    3
 4    4

[5 rows x 1 column]
Press q to quit  ↑←↓→ to move  wasd to page  t to toggle types  g to jump

As you can see there is no need to navigate the Frame here. Is there a way to stop doing this for all python datatable Frames?

Thanks!

Answer 1

As of 4/10/19, the latest version in github turns off the interactivity by default. Before 0.9.0 release we'd have to compile it from source to get it.

Answer 2

In the current dev version, and in future datatable 0.9+ the display will be non-interactive by default. This behavior can be controlled via option dt.options.display.interactive = True|False .

In datatable 0.8 and younger, there are 2 ways to prevent the interactive prompt when displaying a Frame:

• either using Frame.view(False) :

   In [1]: import datatable as dt In [2]: DT = dt.Frame(A=range(5)) In [3]: DT.view(False) A --- -- 0 0 1 1 2 2 3 3 4 4 [5 rows x 1 column] In [4]:

• or change the default behavior via

  In [4]: dt.Frame.view.__defaults__ = (False,) In [5]: DT A --- -- 0 0 1 1 2 2 3 3 4 4 [5 rows x 1 column]
