The Incredible Growth of Python!
Python has been growing rapidly in the
last few years based on data from Stack
overflow.
More information on this trend along
with future projections is available in
David Robinson’s blog published on
09/06/2017.

Pros and Cons of Python
• Easy to Use and Fast to Develop
• Open Source
• Abundant libraries – from web
development through game development
to machine learning
• Great for Prototypes – Ability to achieve
more with less lines of code
• Speed limitations
• Problems with threading
• Not native to mobile development
Python is not a perfect fit for all projects but it can be a very good choice in many use cases.
This language is an obvious choice for machine learning, data analysis and visualization.

Getting Started: First Python Program
print('Hello World')
Hello World
Alternatively;
Our First Python Program prints out “Hello World”.
print(“Hello World”)
Hello World

Floats
• Floats are representation of fractional numbers in a computer memory
• Numbers like 0.67, 3.6, 25.4445, 9.0 are floats
• Notice in the previous section;
 Division of 2 integers results in a float
 Operation on an integer and a float results in a float

11. Python workshop by Ebad ullah Qureshi
Strings
# String Addition
print('IEEE ' + 'N2E ' + 'Python Workshop„)
# String Multiplication
print('python ' * 5)
• Data type for storing text
• Generally created by enclosing text in single quotes
• Python allows
 addition of strings
 multiplication of a string with an integer

Variables – I
• Variables are reserved memory locations to store values
• Python variables do not need explicit declaration to reserve memory space.
• The declaration occurs when the variable is assigned a value using the assignment operator(=)
• Python allows you to assign a single value to several variables simultaneously. This value will
be stored at a single memory location. For example:
• Python also allows multiple variables to be assigned at once. For Example
var = 'python‟ # the value python is assigned to the variable var
a = b = c = 100

13. Python workshop by Ebad ullah Qureshi
Variables – II
• Variables can be reassigned as many times as you want.
• In Python, variables do not have a Specific type and therefore be assigned a string and then
later an integer.
• Variable names do not start with numbers. By convention, all variable names are lower case
with ‘_’ between letters.
• Trying to reference a variable with no value assigned causes an error.

Assignment Operators
var_x = 8
var_y = 6
var_y += 4 # y=y+4
var_x /= 2 # x=x/2
print(var_x)
print(var_y)

Assignment operators are used to assign values to variables.

Comparison Operators
print(100 == 100)
print(110 > 110)
print(134 >= 134)
print(143 < 293)
print(456 <= 345 or "N2E" != "IEEE")
True
False
True
True
True
Comparison Operators compare two values and output a logical True or False

16. Python workshop by Ebad ullah Qureshi
Logical Operators
print(True and False) # Logical AND
print(True or False) # Logical OR
print(not False) # Logical
False
True
True
Logical Operators operate on Boolean values of True and False.
