larray.set_options

class larray.set_options(**kwargs)

Set options for larray in a controlled context.

Currently supported options:

• display_precision: number of digits of precision for floating point output. Print as many digits as necessary to uniquely specify the value by default (None).

• display_width: maximum display width for repr on larray objects. Defaults to 80.

• display_maxlines: Maximum number of lines to show. All lines are shown if -1. Defaults to 200.

• display_edgeitems : if number of lines to display is greater than display_maxlines, only the first and last display_edgeitems lines are displayed. Only active if display_maxlines is not -1. Defaults to 5.

Examples

>>> from larray import *
>>> arr = ndtest((500, 100), dtype=float) + 0.123456

You can use set_options either as a context manager:

>>> with set_options(display_width=100, display_edgeitems=2):
...     print(arr)
 a\b            b0            b1            b2  ...           b97           b98           b99
  a0      0.123456      1.123456      2.123456  ...     97.123456     98.123456     99.123456
  a1    100.123456    101.123456    102.123456  ...    197.123456    198.123456    199.123456
 ...           ...           ...           ...  ...           ...           ...           ...
a498  49800.123456  49801.123456  49802.123456  ...  49897.123456  49898.123456  49899.123456
a499  49900.123456  49901.123456  49902.123456  ...  49997.123456  49998.123456  49999.123456

Or to set global options:

>>> set_options(display_maxlines=10, display_precision=2) 
>>> print(arr) 
 a\b        b0        b1        b2  ...       b97       b98       b99
  a0      0.12      1.12      2.12  ...     97.12     98.12     99.12
  a1    100.12    101.12    102.12  ...    197.12    198.12    199.12
  a2    200.12    201.12    202.12  ...    297.12    298.12    299.12
  a3    300.12    301.12    302.12  ...    397.12    398.12    399.12
  a4    400.12    401.12    402.12  ...    497.12    498.12    499.12
 ...       ...       ...       ...  ...       ...       ...       ...
a495  49500.12  49501.12  49502.12  ...  49597.12  49598.12  49599.12
a496  49600.12  49601.12  49602.12  ...  49697.12  49698.12  49699.12
a497  49700.12  49701.12  49702.12  ...  49797.12  49798.12  49799.12
a498  49800.12  49801.12  49802.12  ...  49897.12  49898.12  49899.12

To put back the default options, you can use:

>>> set_options(display_precision=None, display_width=80, display_maxlines=200, display_edgeitems=5)
...
