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.")

.

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)

#code_challenge write a code that take a name and age from the user then calculate the age of the user's age on next year and show the result like 'hello abebe next year,you will be 33' share your answer to us @zprogramming_bot

The answer for the above question :
Here's detailed explanation

1. Prompting the User:
   You can provide a message or prompt inside the parentheses of the input() function. This message will be displayed to the user, asking them for input. For example:

   name = input("Enter your name: ")

   In this case, "Enter your name: " is the prompt that will be displayed to the user.

2. Storing User Input:
   The value entered by the user is returned by the input() function and can be stored in a variable for further use. In the example above, the user's input will be stored in a variable called name.

3. Handling User Input:
   By default, input() treats all user input as strings. If you want to perform numerical operations on user input, you need to convert it into an appropriate data type (e.g., integer or float). You can use type casting functions like int() or float() for this purpose.

   age = int(input("Enter your age: "))

   Here, we are converting the user's input into an integer using int(). If the user enters something that cannot be converted into an integer (e.g., "abc"), it will raise a ValueError.

4. Using User Input:
   Once you have stored the user's input in a variable, you can use it in your program as needed. For example:
   print("Hello", name)
   print("Next year, you will be", age + 1)

   Here, we are printing a greeting message using the user's name and calculating their age for the next year by adding 1 to the inputted age.
     The answer is:

name = input("Enter your name: ")
age = int(input("Enter your age: "))
print("Hello", name)
   print("Next year, you will be", age + 1)

what is list in python?

Lists are one of the most commonly used data structures in Python. They are used to store a collection of items, such as numbers, strings, or even other lists. Lists are mutable, which means you can modify them by adding, removing, or changing elements.

Creating a List:
To create a list, you can enclose a comma-separated sequence of items within square brackets (). For example:

fruits = ["apple", "banana", "orange"]

Accessing Elements:
You can access individual elements in a list using their index. The index starts from 0 for the first element, 1 for the second element, and so on. For example:

fruits = ["apple", "banana", "orange"]
print(fruits[0])  # Output: apple
print(fruits[1])  # Output: banana

Modifying Elements:
You can modify elements in a list by assigning a new value to a specific index. For example:

fruits = ["apple", "banana", "orange"]
fruits[1] = "grape"
print(fruits)  # Output: ["apple", "grape", "orange"]

Adding Elements:
You can add elements to a list using the append() method, which adds an item to the end of the list. For example:

fruits = ["apple", "banana", "orange"]
fruits.append("mango")
print(fruits)  # Output: ["apple", "banana", "orange", "mango"]

Removing Elements:
You can remove elements from a list using the remove() method, which removes the first occurrence of the specified item. For example:

fruits = ["apple", "banana", "orange"]
fruits.remove("banana")
print(fruits)  # Output: ["apple", "orange"]

List Length:
You can find the length of a list using the len() function. For example:

fruits = ["apple", "banana", "orange"]
print(len(fruits))  # Output: 3

List Slicing:
You can extract a portion of a list using slicing. Slicing allows you to specify a range of indices to extract. For example:

numbers = [1, 2, 3, 4, 5]
print(numbers[1:4])  # Output: [2, 3, 4]
