3. INTRODUCTION TO ANACONDA
Anaconda is an open-source distribution for
python. It is used for data science, machine
learning, deep learning, etc.
With the availability of more than 300 libraries
for data science, it becomes fairly optimal for
any programmer to work on anaconda for data
science.
Anaconda comes with a wide variety of tools to
easily collect data from various sources using
various machine learning and AI algorithms.

Anaconda Navigator is a graphical user interface (GUI) included in allows
you to launch applications and easily manage packages, environments, and
channels without using command-line commands.

13. Data type
• Data type refers to the type and size of data. Variables
can hold values of different data types. Python is a
purely object oriented language. It refers to everything
as an object, including numbers and strings.
• The six standard data types supported by python
includes:

14. NUMBER
Number refers to a numeric value. It includes integers,
floating point, and complex numbers
Example:
a = 5
print(a, type(a))
a = 2.0
print(a, type(a))
Output:
5 <class 'int'>
2.0 <class 'float'>

16. • List is an ordered sequence of items. All the items
in a list do not need to be of the same type.
• Lists are mutable. The elements in the list can be
modified.
• To declare a list in python, separate the items
using commas and enclose them within square
brackets [ ].
Example:
>>>a = [5,10,15,20,25,30,35,40]
>>>a[2]

20. TUPLE
• Tuple is an ordered sequence of items same as list.
The only difference is that tuples are immutable.
Tuples once created cannot be modified.
• It is defined within parentheses ( ) where items are
separated by commas
Example:
T=("apple","banana","cherry")
print(T)
T=("apple","banana","cherry")
print(T[1])
banana

21. TUPLE ARE IMMUTABLE
>>> T=(1,"rit",5,7,10)
>>> T
(1, 'rit', 5, 7, 10)
>>> T[3]=4
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
T[3]=4
TypeError: 'tuple' object does not support item
assignment

22. STRING
• A String in python can be a series or a
sequence of alphabets, numerals and
special characters.
• Single quotes or double quotes are used to
represent strings.
• >>> s = "This is a string"
• Strings are immutable.

23. EXAMPLE OF STRING
>>> c="Ramco Institute of Technology"
>>> c
'Ramco Institute of Technology'
>>> print(c)
Ramco Institute of Technology
>>> c[4]
'o'
>>> c[7]
'n'
>>> c[4]="l"
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
c[4]="l"
TypeError: 'str' object does not support item assignment

24. DICTIONARY
A dictionary is a collection which is unordered, changeable and
indexed.
In Python dictionaries are written with curly brackets, and they
have keys and values
Example:
>>> D={"Name":"Latha","Age":20}
>>> D
{'Name': 'Latha', 'Age': 20}
>>> D["Name"]
'Latha'
>>> D["Name"]="Sudha"
>>> D
{'Name': 'Sudha', 'Age': 20}
>>>

26. SET

26
Set is an unordered collection of data type that is
iterable, mutable and has no duplicate elements.
Sets can be created by using the built-in set()
function with an iterable object or a sequence by
placing the sequence inside curly braces,
separated by ‘comma’. A set contains only
unique elements.
The major advantage of using a set, as opposed
to a list, is that it has a highly optimized method
for checking whether a specific element is
contained in the set.
