4 ways in the four kinds of methods of an object in the Python Python reverse reverse output a target output

Four methods of an object in the Python reverse output

 

Python four methods will target a reverse output
will use it to illustrate the list:

Copy the code
>>> lst = [1,2,3,4,5,6] # Creating list of Test 

# Method. 1: 
>>> lst.reverse () #reverse () inverted 
>>> LST 
[. 6,. 5,. 4 , 3, 2, 1] 

method # 2: 
>>> LST1 = [I for I in the reversed (LST)] #reversed only applies to the sequence (a list of tuples, string) 
>>> LST1 
[. 6,. 5 , 4, 3, 2, 1] 

method # 3: 
>>> lst2 the sorted = (LST, Reverse = True) # + Reverse applied to the sorted sequence (list, tuple, string), sets, dictionary 
>>> lst2 
[6, 5, 4, 3, 2, 1] 

method # 4: 
>>> lst3 LST = [:: - 1] # slice usage: create a string with the reverse order of the original string 
>>> lst3 
[6 , 5, 4, 3, 2, 1]
