# numpy.arange

`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 including start but excluding stop). For integer arguments the function is equivalent to the Python built-in range function, but returns a ndarray rather than a list.

  Parameters : | start : number, optional Start of interval. The interval includes this value. The default start value is 0. stop : number End of interval. The interval does not include this value. step : number, optional Spacing between values. For any output out, this is the distance between two adjacent values, `out[i+1] - out[i]`. The default step size is 1. If step is specified, start must also be given. dtype : dtype The type of the output array. If dtype is not given, infer the data type from the other input arguments.
  Returns : | out : ndarray Array of evenly spaced values. For floating point arguments, the length of the result is `ceil((stop - start)/step)`. Because of floating point overflow, this rule may result in the last element of out being greater than stop.
