How to generate digital sequence by python
This article mainly explains "python how to generate digital sequence", the content of the explanation is simple and clear, easy to learn and understand, now please follow the editor's ideas slowly in depth, together to study and learn "python how to generate digital sequence" bar!
Range () syntax
Range (start, stop [, step])
Parameter description
Start: the count starts with start. The default is 0, for example, range (5) is equivalent to range (0,5)
Stop: count to the end of stop, but does not include stop, for example: range (0,5) is [0,1,2,3,4] without 5
Step: step size, default is 1, for example: range (0,5) is equivalent to range (0,5,1)
Example
> range (10) # from 0 to 10
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
> range (1,11) # from 1 to 11
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
> range (0,30,5) # step size is 5
[0, 5, 10, 15, 20, 25]
> range (0,10,3) # step size is 3
[0, 3, 6, 9]
> range (0,-10,-1) # negative
[0, 1,-2,-3,-4,-5,-6,-7,-8,-9]
> range (0)
[]
> range (1,0)
