linspace produces a numpy array, not a list. Don't confuse the two.

In [3]: x = np.linspace(0,100,10)
In [4]: x
Out[4]: 
array([  0.        ,  11.11111111,  22.22222222,  33.33333333,
        44.44444444,  55.55555556,  66.66666667,  77.77777778,
        88.88888889, 100.        ])

The numbers will look nicer if we take into account that linspace includes the end points:

In [5]: x = np.linspace(0,100,11)
In [6]: x
Out[6]: array([  0.,  10.,  20.,  30.,  40.,  50.,  60.,  70.,  80.,  90., 100.])

As an array, we can simply add a scalar; no need to write a loop:

In [7]: x + 1
Out[7]: array([  1.,  11.,  21.,  31.,  41.,  51.,  61.,  71.,  81.,  91., 101.])

range takes one number (or 3), but never an array (of more than 1 element):

In [8]: for i in range(5): print(i)
0
1
2
3
4

We can't modify i in such a loop, or the "x" used to create the range. But we can write a list comprehension:

In [9]: [i+1 for i in range(5)]
Out[9]: [1, 2, 3, 4, 5]
