We can Create and Assign List by Insert, Append Length, Index, Remove and Extend, etc..
Lists are mutable and the changeble object is enclosed within the square brackets i.e [ ], Lists in python is easy.
Example
list =["Tutorials ","Point", "Pvt","Ltd"] list
Output
['Tutorials ', 'Point', 'Pvt', 'Ltd']
Assign Values in Lists To assign values in lists, use square brackets
Example
list1 = ['physics', 'chemistry', 1997, 2000]; list2 = [1, 2, 3, 4, 5, 6, 7 ]; print ("list1[0]: ", list1[0]) print ("list2[1:5]: ", list2[1:5])
When the above code is executed, Following is the preceding output
Output
list1[0]: physics list2[1:5]: [2, 3, 4, 5]
append() and extend() in python append add its argument/parameter as a single element at the end of a list. the list length will increase by one.
Example
list=['Red','Green','Yellow','Purple','White','Black'] list.append('Orange') print(list)
Output
['Red', 'Green', 'Yellow', 'Purple', 'White', 'Black', 'Orange']
extend() iterates over its parameter adding each element to the list and extending the list length of the list will increase through the iterable argument
Example
list=['Car','Bike','Scooty','Bus','Metro'] list.extend('Car') print(list)
When the above code is executed, Following is the preceding output
Output
['Car', 'Bike', 'Scooty', 'Bus', 'Metro', 'C', 'a', 'r']
Index: Index method can search easily, that expects a value is to be searched
Example
list=['Car','Bike','Scooty','Bus','Metro'] list.index('Scooty')
Output
2
