Difference between range and arange?

1.

>>> x=np.arange(1,10)
>>> x
array([1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> print(x)
[1 2 3 4 5 6 7 8 9]        #No commas
>>> type(x)
<type 'numpy.ndarray'>


>>> x=range(1,10)
>>> x
[1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> print(x)
[1, 2, 3, 4, 5, 6, 7, 8, 9]  # is separated by commas
>>> type(x)
<type 'list'>


2.
>>> x=np.arange(10.5)  # Floating point value
>>> x
array([  0.,   1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])
>>> print(x)
[  0.   1.   2.   3.   4.   5.   6.   7.   8.   9.  10.]

>>> x=range(10.5)
