range xrange

The following are the details of the "collation": The First looks at the following example: >>> x=xrange (0,8) >>>  print x Xrange (8) >>> print x[0] 0 >>> print x[7] 7 > >> print x[8] Traceback (most recent call last)

Range vs. Xrange Rangefunction Usage:Range (stop)Range (Start,stop[,step])function Description:This is a generic function that creates a list that contains a sequence of columns. It is most commonly used for a For loop. The parameter must be a

These two are basically used at the time of the cycle. forIinchRange0, -):p rint i forIinchXrange0, -):p rint I the results of both outputs are the same, in fact there are many differences, and range generates a list object directly: a= Range (0, -)

One, two functions of the document:1,xrange (): xrange ( stop ) xrange ( start, stop[, step] ) This function was very similar to range () , but returns an Xrange

Whether range () or xrange () is a built-in function in Python. The two built-in functions are most commonly used in the For loop. Range () and xrange () are two different implementations in Python 2. But in Python 3, the implementation of range ()

1.range () function:Function Description: Range ([Start,] stop[, step]), which generates a sequence based on the range specified by start and stop and step set by step.>>>#The range () function does not support 0 parameters... >>>range () Traceback (

Let's take a look at the usage of range and xrangeHelp (Range)Help on built-in function range in module __builtin__:Range (...)Range (stop), List of integersRange (start, stop[, Step), List of integersReturn a list containing an arithmetic

Range Function Description: Range ([Start,] stop[, step], which generates a sequence based on the range specified by start and stop, and steps that are set. Range Example: The code is as follows Copy Code >>> Range (5)[

RangeFunction Description: Range ([Start,] stop[, step]), which generates a sequence based on the range specified by start and stop and step set by step.Range Example: >>> Range(5) [0, 1, 2, 3, 4] >>> Range(1,5) [1, 2, 3, 4

A range ([Start,] stop[, step]) is specified in the previous section of a, and a sequence is generated based on the range defined by start and stop and step set by step.Like what:>>> Range (5)[0, 1, 2, 3, 4]>>> Range (1,5)[1, 2, 3, 4]>>> Range (0,6,2
