Python learning-data sorting method

Python sorts data in two ways:

1. In-situ sorting: the sort () method is used to sort data in the specified order and then replace the original data with the sorted data (the original order is lost), for example:

>>> Data1 = [6,432, 22,896, 42,677, 12] >>> data1.sort () >>> data1 # replace the original sequence with [2, 4, 6, 12, 22, 42, 43, 78,432,677,896]

 

2. Copy sorting: using the built-in sorted () function, Sort data in the specified order and return an ordered copy of the original data (the original order is retained), for example:

>>> Data1 = [6,432, 22,896, 42,677, 6,432, 12] >>> data2 = sorted (data1) >>> data1 [4, 2, 78, 43, 22,896, 42,677, 12] # original order reserved> data2 [2, 4, 6, 12, 22, 42, 43, 78,432,677,896] # Sort copies>
