The numpy.arange() function is used to generate an array with evenly spaced values within a specified interval. The function returns a one-dimensional array of type numpy.ndarray.Syntax:numpy.arange([start, ]stop, [step, ]dtype=None)
NOTE: This function is a bit different from numpy.linspace(), which, by default, includes both the starting and the endpoints for the sequence calculation. It also does not take the step size as an argument, but rather takes only the number of elements in the sequence. 注意:此函数与numpy...
numpy.arange([start, ]stop, [step, ]dtype=None) Return evenly spaced values within a given interval. Values are generated within the half-open interval[start, stop)(in other words, the interval includingstartbut excludingstop). For integer arguments the function is equivalent to thePythonbuilt-...
numpy.arange([start, ]stop, [step, ]dtype=None) Return evenly spaced values(均匀间隔的值) within a given interval. Values are generated within the half-open interval [start, stop) (in other words, the interval including start but excluding stop). For integer arguments the function is equiva...
For integer arguments the function is equivalent to the Python built-in `range` function, but returns an ndarray rather than a list. When using a non-integer step, such as 0.1, the results will often not be consistent. It is better to use `numpy.linspace` for these cases. ...
In this step-by-step tutorial, you'll learn how to use the NumPy arange() function, which is one of the routines for array creation based on numerical ranges. np.arange() returns arrays with evenly spaced values.

Hi there! In this lesson I’m going to take you through NumPy’s arange() function, its parameters, and how you might go about using it. So, what is the arange() function? Well, as you might guess from its name, it returns a range of numeric values…
