This article mainly introduces what is the difference between range, np. range and np.linspace in Python. The introduction in the article is very detailed and has certain reference value. Interested friends must read it!

1. range

range is a Python built-in class that represents an immutable sequence of numbers, often used to iterate over a special set of numbers in a for loop. Its prototype can be approximated as follows:

class range(stop)class range(start, stop, step=1)

(Note that Python does not allow the definition of two class initialization functions, in fact, its CPython implementation is more like passing in variable length parameters *args, and then according to len(args) to carry out different splitting, but we follow Python documentation style here)

If only the stop parameter is passed in, then we iterate by default in steps of 1 in the interval [0, stop). If we pass 2 or 3 arguments, we iterate over the interval [start, stop) in step sizes (optional, default 1). Note that all three parameters must be integer values.

Examples of its common uses are as follows:

print(list(range(10)))# [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]print(list(range(0, 30, 5)))# [0, 5, 10, 15, 20, 25]
