INTRODUCTION
What is Python ?
● Python is a high –level interpreted programming
language that is known for its simplicity , readability and
versatality.
● It was created in the late 1980s by Guido van Rossum
and had since become one of the most popular
programming language.
● KEY FEATURES : Dynamic typing , automatic memory
management, modularized , open - source
*

BASIC CONCEPTS
• Variables are the
placeholders of data.
• They must not be a
keyword,start with numeric
caharacter or a special
symbol.
• input() : Used to get the input
from the user. Can be type
casted
• print() :
< INPUT/OUTOUT > Variables
{
}

Python Synatx Basics
Practical EXERCISE 01
Exercise : Program To print the BMI( Body
Mass Index)
Height = float(input(“Enter your height in cm. )
Weight = float(input(“Enter your weight in kg.)
BMI = Height/(Weight*Weight)
float_BMI = float(BMI)
print(f”Your BMI is {float_BMI} )
Expected Output :
Enter your height in cm. 167
Enter your weight in kg. 75.2
Your BMI is 27.0

Concepts Learned
In Python Indentation
matters the most !!!!
In python string and
numeric data can be
used together with ‘f’
character
Type casting of
variables using ()
paranthesis and data
type outside.
This returns the data
type as class.
Ex. Class <int>
Indenatation
Type Casting
F - strings
Type Checking

PYTHON FUNDAMENTALS
02 {
} ..
..

It includes
int,float,complex for
numerical.
It includes dict
For creating
dictionary.
Here are PYTHON DATE TYPES :
It includes str
data type for textual
data.
It includes keyword
‘bool’ for representing
true or false values.
It indicates none data
type.
It includes set,
frozenset.
TEXT NUMERIC MAPPING
BOOLEAN NONE SET

} ..

PYTHON LIBRARIES AND FRAMEWORKS
● The major difference between frameworks and libraries
is complexity.
● Library offers fewer complexities but frameworks are
opposite.
● Example of frameworks are : Django, Flask, Flask,
CherryPy etc.
● Examples of Libraries are :TensorFlow, Numpy,
● keras, PyTorch etc.
}
..

FILE HANDLING IN PYTHON
● Python provides several functions for
creating, reading, updating and deleting files
.
● The key functions for working with files are
open(), read(), write() and close().
}
..

Practical Exercise 02
# Creating a text file with the command function ‘x’ :
● f = open(“myfile.txt”, “x”)
# Inserting the string into the text file using write() method :
● file.write(“Hello Theren”)
# Reading from a text file using read() method :
● f = open(“myfile.txt”, “x”)
● print(f.read())

A Picture Is Worth a Thousand Words

REGISTRATION FORM
Here In this section we are going to implement a
Registration Form using Tkinter GUI method libraray and
MYSQL Database.
● Tkinter is a Python library for developing GUI
(Graphical User Interfaces). We use the Tkinter library
for creating an application of UI (User Interface), to
create Windows and all other graphical user
interfaces.
} ..

{ Here we have
used Pycharm
IDE and created
our
File . }

This is the code for creating table ‘user’
and importing modules.

CODE FOR
THE GUI
This is the Entire Source code for the
GUI

...

OUTPUT
This is the actual Registration form
that will appear.
