A list contains items separated by commas and enclosed within square brackets [].lists are almost similar to arrays in C. One difference is that all the items belonging to a list can be of different data type.
list = [123,'abcd',10.2,'d'] #can be a array of any data type or single data type.
list1 = ['hello','world']
print(list) #will ouput whole list. [123,'abcd',10.2,'d']
print(list[0:2]) #will output first two element of list. [123,'abcd']
print(list1 * 2) #will gave list1 two times. ['hello','world','hello','world']
print(list + list1) #will gave concatenation of both the lists. [123,'abcd',10.2,'d','hello','world']
