A variable in Python is a named location in memory that stores a value or data.

Q2 How do you declare a variable in Python?

To declare a variable in Python, you simply assign a value to a name using the equal sign (=) operator. For example, to declare a variable named "x" with a value of 5, you would write "x = 5". 😎

Q3 What are the rules for naming variables in Python?

Variable names in Python must start with a letter or underscore, and can only contain letters, numbers, and underscores. They are case-sensitive and cannot be a reserved keyword🤙

Answer
4,The scope of a variable in Python refers to the region of the program where the variable is accessible. There are two types of scope in Python: global scope and local scope
5,To access the value of a variable in Python, you simply refer to its name. For example, if you have a variable named "x", you can access its value by writing "x".
6,To change the value of a variable in Python, you simply assign a new value to its name using the equal sign (=) operator. For example, if you have a variable named "x" with a value of 5, you can change its value to 10 by writing "x = 10".

In Python, data types are used to classify and represent different types of data that can be stored and manipulated within a program. Python is a dynamically typed language, which means that the data type of a variable is determined at runtime based on the value assigned to it. Here are some commonly used data types in Python:

1. Numeric Types:
- int: Represents integer values, such as 1, -5, or 1000.
- float: Represents floating-point numbers with decimal places, such as 3.14 or -2.5.
- complex: Represents complex numbers in the form of a + bj, where a and b are real numbers and j is the imaginary unit.

2. Sequence Types:
- str: Represents a sequence of characters, such as "Hello, World!" or "Python".
- list: Represents an ordered collection of items, enclosed in square brackets (), and separated by commas. Lists can contain elements of different data types.
- tuple: Similar to lists, but enclosed in parentheses (()) and are immutable, meaning their values cannot be changed once assigned.

3. Mapping Type:
- dict: Represents a collection of key-value pairs enclosed in curly braces ({}). Each key-value pair is separated by a colon (:), and keys must be unique.

4. Set Types:
- set: Represents an unordered collection of unique elements, enclosed in curly braces ({}).
- frozenset: Similar to sets, but immutable.

5. Boolean Type:
- bool: Represents a boolean value, which can be either True or False.

6. None Type:
- None: Represents the absence of a value or a null value.

Python also provides the ability to convert between different data types using built-in functions like int(), float(), str(), etc.

Understanding and utilizing the appropriate data types in Python is crucial for performing various operations and ensuring the correctness and efficiency of your code.

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.")
