This article refers to "Python programming: from getting started to practicing", Eric Matthes, translator: Ching

Operation	Grammar	Example	Results
modifying elements		Motocycles = [' Honda ', ' Yamaha ', ' Suzuki '] Print (Motocycles) Motocycles[0] = ' Ducati ' Print (Motocycles)	[' Honda ', ' Yamaha ', ' Suzuki '] [' Ducati ', ' Yamaha ', ' Suzuki ']
add element	Add an element at the end of the list: Append ()	motocycles = [' Honda ', ' Yamaha ', ' Suzuki '] print (motocycles)   motocycles.append (' Ducati ') print (motocycles)	[' Honda ', ' Yamaha ', ' Suzuki ']   [' Honda ', ' Yamaha ', ' Suzuki ', ' Ducati ' ]
		motocycles = [' Honda ', ' Yamaha ', ' Suzuki '] print (motocycles)   motocycels.insert (0, ' Ducati ') Print (motocycles)	[' Honda ', ' Yamaha ', ' Suzuki ']   [ ' Ducati ' , ' Honda ', ' Yamaha ', ' Suzuki ']
delete element	Delete by index: Del, unable to continue using	motocycles = [' Honda ', ' Yamaha ', ' Suzuki '] Print (motocycles)   del motocycles[1] print (motocycles)	[' Honda ', ' Yamaha ', ' Suzuki ']   [' Honda ', ' Suzuki ']
	Delete the element at the end: Pop (), you can continue using can also be deleted according to the index, such as Motocycles.pop (0)	Motocycles = [' Honda ', ' Yamaha ', ' Suzuki '] Print (motocycles)   popped_motocycle = Motocycles.pop () print (motocycles) print (popped_motocycle)	[' Honda ', ' Yamaha ', ' Suzuki ']   [' Honda ', ' Yamaha ']   suzuki
	when you do not know the index, delete the element by value: Remove (), you can continue using	motocycles = [' Honda ', ' Yamaha ', ' Suzuki ', ' Ducati '] Print (motocycles)   too_expensive = ' Ducati ' motocycles.remove (too_expensive) print (motocycles) print (too_expensive)	[' Honda ', ' Yamaha ', ' Suzuki ', ' Ducati ']   [' Honda ', ' Yamaha ', ' Suzuki ']   ducati
element sort	permanent sort: sort ()   Sort in reverse direction: sort (reverse = True)	Cars = [' BMW ', ' Audi ', ' Toyota ', ' Subaru '] Print (Cars   cars.sort () Print (cars)   Span style= "COLOR: #000000" >cars = [' BMW ', ' Audi ', ' Toyota ', ' Subaru '] Cars.sort (reverse = True) Print (cars)	[' BMW ', ' Audi ', ' Toyota ', ' Subaru ']   [' Audi ', ' BMW ', ' Subaru ', ' Toyota ']   [' Toyota ', ' Subaru ', ' BMW ', ' Audi ']
	temporary sort: sorted ()   Span style= "COLOR: #0000ff" > sort in reverse direction : sorted (reverse = True)	Cars = [' BMW ', ' Audi ', ' Toyota ', ' Subaru '] Print (cars) print (sorted (cars)) print (Cars)	[' BMW ', ' Audi ', ' Toyota ', ' Subaru ']   [' Audi ', ' BMW ', ' Subaru ', ' Toyota ']   [' BMW ', ' Audi ', ' Toyota ', ' Subaru ']
	Permanently reverse the order of list elements: reverse ()	Cars = [' BMW ', ' Audi ', ' Toyota ', ' Subaru '] Print (Cars) Cars.reverse () Print (Cars) Cars.reverse () Print (Cars)	[' BMW ', ' Audi ', ' Toyota ', ' Subaru '] [' Subaru ', ' Toyota ', ' Audi ', ' BMW '] [' BMW ', ' Audi ', ' Toyota ', ' Subaru ']
