在 Python 2.7 中,如何在具有固定数量元素的范围内创建列表,而不是每个元素之间的固定步长?
In Python 2.7, how can I create a list over a range with a fixed number of elements, rather than a fixed step between each element?
>>> # Creating a range with a fixed step between elements is easy:
>>> range(0, 10, 2)
[0, 2, 4, 6, 8]
>>> # I'm looking for something like this:
>>> foo(0, 10, num_of_elements=4)
[0.0, 2.5, 5, 7.5]
我为此使用 numpy.
I use numpy for this.
>>> import numpy as np
>>> np.linspace(start=0, stop=7.5, num=4)
array([ 0. , 2.5, 5. , 7.5])
>>> list(_)
[0.0, 2.5, 5.0, 7.5]
