Practical example: Output:
The fruit list contains fruit_name and a property that speaks about its fruit. The other list contains two juices and is . With pop () and # Python3 program demonstrating
# practical use of the pop () list fruit = [[ ’Orange’ , ’ Fruit’ ], [ ’Banana’ , ’Fruit’ ], [ ’ Mango’ , ’ Fruit’ ]] consume = [ ’ Juice’ , ’Eat’ ] possible = []
# Loop through an item in the fruit list for item in fruit: # Heavy list use consume for use in consume: item.append (use) result.append (item [:]) item.pop ( - 1 ) print (result) [[’Orange’,’ Fruit’, ’Juice’], [’ Orange’, ’Fruit’,’ Eat’], [’Banana’,’ Fruit’, ’Juice’], [’ Banana’, ’ Fruit’, ’Eat’], [’ Mango’, ’Fruit’,’ Juice’], [’Mango’,’ Fruit’, ’Eat’]]
