Welcome to your first day of Python programming! Today, we will be introducing you to the basics of Python programming and getting you started on your journey to becoming a proficient Python programmer.

First, let's start with the basics. Python is a high-level, interpreted programming language that is widely used for web development, data analysis, artificial intelligence, and many other applications. It is known for its simplicity, readability, and ease of use, making it a great language for beginners to learn.

To get started with Python, you will need to install Python on your computer. You can download the latest version of Python from the official Python website (https://www.python.org/downloads/). Once you have installed Python, you can open the Python interpreter, which is a command-line interface that allows you to enter Python code and see the results.

Let's start with a simple example. Open the Python interpreter and type the following code:

print("Hello, world!")


Press enter, and you should see the output "Hello, world!" printed on the screen. Congratulations, you have just written your first Python program!

Now, let's take a closer look at the code. The print() function is a built-in function in Python that allows you to print text to the screen. In this case, we are printing the text "Hello, world!" to the screen. The text is enclosed in double quotes, which tells Python that it is a string.

Next, let's talk about variables. In Python, a variable is a name that represents a value. You can assign a value to a variable using the assignment operator =. For example:

x = 5


This assigns the value 5 to the variable x. You can then use the variable x in your code:

print(x)


This will print the value of x, which is 5.

Variables can also be assigned to other variables:

x = 5
y = x
print(y)


This will print the value of y, which is also 5, because we assigned y to the value of x.

You can also perform arithmetic operations on variables:

x = 5
y = 3
print(x + y) # prints 8
print(x - y) # prints 2
print(x * y) # prints 15
print(x / y) # prints 1.6666666666666667


This will perform arithmetic operations on the variables x and y and print the results to the screen.

That's it for today's lesson! We hope you have enjoyed your introduction to Python programming, and we look forward to teaching you more in the coming days.

Tutorial: Python If-Else Condition Basics

1. Introduction to If-Else Conditions:
- In programming, if-else conditions are used to make decisions based on certain conditions.
- If a condition is true, a specific block of code is executed. Otherwise, an alternative block of code is executed.

2. Syntax of If-Else Statements:
- The basic syntax of an if-else statement in Python is as follows:

if condition:
    # code to be executed if the condition is true
else:
    # code to be executed if the condition is false

3. Simple If-Else Statements:
- Let's start with a simple example to understand the concept:

age = 18

if age >= 18:
    print("You are eligible to vote!")
else:
    print("You are not eligible to vote yet.")

4. Comparison Operators:
- Comparison operators are used to compare values in if-else conditions. Here are some commonly used comparison operators:
- > : Greater than
- < : Less than
- == : Equal to
- != : Not equal to
- >= : Greater than or equal to
- <= : Less than or equal to

5. Logical Operators:
- Logical operators are used to combine multiple conditions in if-else statements. Here are the commonly used logical operators:
- and : Returns True if both conditions are true
- or : Returns True if at least one condition is true
- not : Returns the opposite of the condition

6. Nested If-Else Statements:
- Nested if-else statements allow you to have multiple levels of conditions. Here's an example:

age = 25
income = 50000

if age >= 18:
    if income >= 30000:
        print("You are eligible for a loan!")
    else:
        print("You are not eligible for a loan.")
else:
    print("You must be at least 18 years old to apply for a loan.")

7. Elif (Else If) Statements:
- The elif statement allows you to check multiple conditions in a single if-else block. Here's an example:

score = 85

if score >= 90:
    print("You got an A!")
elif score >= 80:
    print("You got a B!")
elif score >= 70:
    print("You got a C!")
else:
    print("You need to improve your score.")

.

This tutorial provides a basic understanding of if-else conditions in Python. Practice writing if-else statements and try solving different problems to strengthen your skills.

How to get input from the user Python :

1. Getting User Input:
To get input from the user, you can use the input() function in Python. It reads a line of text entered by the user and returns it as a string.

Example:

python
   name = input("Enter your name: ")
   print("Hello, " + name)
   

2. Converting Input to Other Data Types:
By default, input() returns the user input as a string. If you need to convert it to other data types like integer or float, you can use type casting.

Example:

python
   age = int(input("Enter your age: "))
   height = float(input("Enter your height (in meters): "))
   

3. Prompting for Multiple Inputs:
You can prompt for multiple inputs by calling input() multiple times and storing the results in different variables.

Example:

python
   num1 = int(input("Enter first number: "))
   num2 = int(input("Enter second number: "))
   
   sum = num1 + num2
   print("Sum:", sum)
   

  

Let me know if you have any further questions.

Example of the importance of Variable

# Define variables to store length and width
length = 5
width = 3

# Calculate the area using the formula (length * width)
area = length * width

# Print the calculated area
print("The area of the rectangle is:", area)

print(total) is out of the for loop
