Learn Python Easy Way - Sets

Let us learn what a set is in Python. We use the term set in our language for example when I say, "I have a set of colours" that means I have a set of some colours that are unique, all different colors. Usually "a set" would denote a unique set of items, and that is how it is implemented in Python. The set in Python is used similar to the "Set Theory" in Mathematics. We can do operations like Union, Intersection, Difference on sets in Python.

Learn Python Easy Way - Tuples

Let us understand Tuples in Python. We had learnt Lists in Python in the previous article. Tuples can be understood in comparison to the Lists.

We created Lists. Lists were a set of objects enclosed in [ ] square braces. Tuples are also a set of objects but they are enclosed in ( ) brackets.

Learn Python Easy way - Dictionaries

Let us see what is a dictionary in Python. Creating a dictionary is like creating a List, a list of coupled objects, pair of objects. A list is an ordered set of objects, and a dictionary is un-ordered set of objects

Objects in a list can be accessed by their index numbers but objects in a dictionary can't. Each object in a dictionary has a Key and a Value. We need to use the key to access it's value. A key woks like the index number. But a key is not necessarily a number. It can be any data type.

Learn Python Easy Way Part 6 Copy Lists

Today lets is see how to copy a list. That means we can copy an entire list or a part of it as a separate list. But it has interesting features to it.

Let us create a list of names of cities

Cities = ['Mumbai', 'Pune', 'Nagpur']

Learn Python Easy way Part 5 Lists

Let us look learn some more ways to work with Python lists.
There one more way to display the element present in a list at a certain location, using the pop method

cities = ["Mumbai", "Pune", "Bangalore", "Calcutta"]
cities.pop(0)
'Mumbai'

Learn Python Easy Way Part 4 (Lists)

Let us continue from where we left in the last article. We will see some more ways to work with lists in Python

Finding numbers of items in a list

mylist = ['Dehli', 'Washington', 'Tokyo']
len(mylist)
 3

Learn Python Easy Way - Part 3

We will look at the sequential data types in Python. They are Strings, Lists and Tuples. You can access a single character in a string by its index.

For Example

Saying = "A Friend in need in a Friend indeed"
print(Saying[0], Saying[3], Saying[4],Saying[7])
A r i d
