Python Learning Notes _ data sorting method

1. Sort in place: Use the sort () method to arrange the data in the order specified and replace the original data with the sorted data (the original order is lost), such as:

Copy the Code code as follows:

>>> data1=[4,2,6,432,78,43,22,896,42,677,12]
>>> Data1.sort ()
>>> data1 #原来的顺序被替换
[2, 4, 6, 12, 22, 42, 43, 78, 432, 677, 896]

2. Copy sort: Using sorted () built-in functions, arrange the data in the order specified to return an ordered copy of the original data (in the original order), such as:

Copy the Code code as follows:

>>> data1=[4,2,6,432,78,43,22,896,42,677,12]
>>> data2=sorted (data1)
>>> data1
[4, 2, 6, 432, 896, 677, A.,] #原顺序保留
>>> data2
[2, 4, 6, A, 432, 677, 896] #对副本排序
>>>
