Usage of the "Python" range

Usage of range:

>>> Range (1,5) #代表从1到5 (not including 5)
[1, 2, 3, 4]
>>> Range (1,5,2) #代表从1到5, Interval 2 (not including 5)
[1, 3]
>>> Range (5) #代表从0到5 (not including 5)
[0, 1, 2, 3, 4]

List operations:

array = [ 1 , 2 , 5 , 3 , 6 , 8 , 4 ] #其实这里的顺序标识是 [ 1 , 2 , 5 , 3 , 6 , 8 , 4 ] ( 0 ， 1 ， 2 ， 3 ， 4 ， 5 ， 6 ) ( - 7 , - 6 , - 5 , - 4 , - 3 , - 2 , - 1 ) >>> array[ 0 :] #列出0以后的 [ 1 , 2 , 5 , 3 , 6 , 8 , 4 ] >>> array[ 1 :] #列出1以后的 [ 2 , 5 , 3 , 6 , 8 , 4 ] >>> array[: - 1 ] #列出-1之前的 [ 1 , 2 , 5 , 3 , 6 , 8 ] >>> array[ 3 : - 3 ] #列出3到-3之间的 [ 3 ]

The swap variable in Python does not require a temporary variable! Such as:

A, b, c = B, c, a

Bubble Sort:

array=[1,2,5,3,6,8,4] for in range (len (array) -1,1,-1):    for in  Range (0,i):        if array[j]>array[j+1]:            array[j],array[j+1]=array[j+1 ],array[j]print array
