Show all values in Numpy array

If an array is too large to be printed, (Scipy)NumPy automatically skips the central part of the array and only prints the corners:

>>> print arange(10000)
[   0    1    2 ..., 9997 9998 9999]
>>>
>>> print arange(10000).reshape(100,100)
[[   0    1    2 ...,   97   98   99]
 [ 100  101  102 ...,  197  198  199]
 [ 200  201  202 ...,  297  298  299]
 ...,
 [9700 9701 9702 ..., 9797 9798 9799]
 [9800 9801 9802 ..., 9897 9898 9899]
 [9900 9901 9902 ..., 9997 9998 9999]]
    

To disable this behaviour and force NumPy to print the entire array, you can change the printing options using

set_printoptions

.

>>> set_printoptions(threshold='nan')
