List is the most used data type in Python. A list can contain the same type of

items. Alternatively, a list can also contain different types of items. A list is

an ordered and indexable sequence.

list1=[34,2,1,22]
list2=[5,2,3,3]
print(list1+list2) #output: list1=[34,2,1,22]

 

List vs Tuple in python

Lists and tuples have the following differences:

• In lists, items are enclosed within square brackets [], whereas in tuples,

items are enclosed within parentheses ().

• Lists are mutable whereas Tuples are immutable. Tuples are read only lists.

Once the items are stored, the tuple cannot be modified.

Example for creating tuple in python:

third=(7, “eight”,9, 10.0)

 

sets in python

Union, Intersection, Difference and Symmetric Difference are some operations

which are performed on sets.

Union: Union operation performed on two sets returns all the elements from both

the sets. It is performed by using & operator.

Intersection: Intersection operation performed on two sets returns all the element

which are common or in both the sets. It is performed by using | operator.

Difference: Difference operation performed on two sets set1 and set2 returns the

elements which are present on set1 but not in set2. It is performed by using –

operator.

Symmetric Difference: Symmetric Difference operation performed on two sets

returns the element which are present in either set1 or set2 but not in both. It is

performed by using ^ operator.

examples of sets in python :

set1 = set([1, 2, 4, 1, 2, 8, 5, 4])
set2 = set([1, 9, 3, 2, 5])
print(set1) #Printing set
#set([8, 1, 2, 4, 5]) #Output
print(set2)

intersection = set1 & set2 #intersection of set1 and set2
print(intersection)

union = set1 | set2 # Union of set1 and set2
print(union) #Output set([1, 2, 3, 4, 5, 8, 9]) 

difference = set1 - set2 # Difference of set1 and set2
print(difference) #Output set([8, 4])

symm_diff = set1 ^ set2 # Symmetric difference of set1 and
print(symm_diff)  #Output set([3, 4, 8, 9])

 

 

Dictionary in python

Dictionaries are used to store data values in key:value pairs.

A dictionary is a collection which is ordered*, changeable and does not allow duplicates.

Example: Create and print a dictionary:

thisdict = {
  "brand": "Ford",
  "model": "Mustang",
  "year": 1964
}
print(thisdict)
