一长串数字 [英] long list of numbers

问题描述

我想用python写一长串数字，但是我不想一个接一个地输入数字，因为那很无聊.那么，我该怎么做呢?对于那些熟悉MATLAB的人，我想写一些看起来像1:100的女巫，但我不知道如何用python编写！ 顺便说一句，我可以在一个循环中为一个元素列表附加数字，但我正在寻找的东西大都类似于内置运算符.

I want to write a long list of numbers in python, but I don't want to enter the numbers one by one because that's boring. So, how can I do that? For the ones who are familiar with MATLAB, I want to write something witch looks 1:100, but I don't know how to write it in python! By the way, I can append numbers for a one-element-list in a loop but I am looking for something mostly like a built in operator.

推荐答案

是否需要类似内置的range函数?

Do you want something like the builtin range function?

>>> range(1,10)
[1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> range(1,10,2)
[1, 3, 5, 7, 9]

在python 3.x中的

，range不再返回列表，而是返回range object.范围对象在很多方面的行为都类似于列表，但实际上并不是列表.如果您确实需要python 3.x上的列表，则可以使用list(range(...))

in python 3.x, range doesn't return a list anymore, it returns a range object. Range objects behave like lists in a lot of ways, but they aren't actually lists. If you really need a list on python 3.x, you can use list(range(...))

Numpy具有类似的功能arange，它也可以与浮点数一起使用:

Numpy has a similar function arange which will work with floats as well:

>>> np.arange(1,2,.1)
array([ 1. ,  1.1,  1.2,  1.3,  1.4,  1.5,  1.6,  1.7,  1.8,  1.9])
