Function summary

Functions

• set_var_value(value)

  Setting values in a BlockVariable to be either None, an int, a float, a string, or a numpy array.

  A few common cases for numpy expressions are checked like 'array', 'arange', 'linspace', 'zeros', and 'ones' and anything 'numpy.foo()'.

  Parameters:

  value : Str

  Returns

  obj : object

  Undefined if we cannot parse this at all. Recipients should check for this value and raise an error to force the Traits UI Editor to do something appropriate. The empty string will evaluate to None.

  Examples

  >>> from enthought.block_canvas.context.ui.context_variable import set_var_value
  >>> set_var_value('') is None
  True
  >>> set_var_value('None') is None
  True
  >>> set_var_value('1')
  1
  >>> set_var_value('10.0')
  10.0
  >>> set_var_value('numpy.array([1,2,3])')
  array([1, 2, 3])
  >>> set_var_value('array([1,2,3])')
  array([1, 2, 3])
  >>> set_var_value('arange(5)')
  array([0, 1, 2, 3, 4])
  >>> set_var_value('linspace(0,1,6)')
  array([ 0. ,  0.2,  0.4,  0.6,  0.8,  1. ])
  >>> set_var_value('zeros([3])')
  array([ 0.,  0.,  0.])
  >>> set_var_value('ones([3])')
  array([ 1.,  1.,  1.])
  >>> set_var_value('"a string"')
  'a string'
  >>> set_var_value('nothing we can evaluate')
  <undefined>
