How to Create and Assign Lists in Python?

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
