If elif else statement in python w3schools using

I'll respond in English this time.

The if-elif-else statement in Python is used to execute different blocks of code depending on the value of a conditional expression. The syntax for this statement is:

if condition: do something elif another_condition: do something else else: do something else if nothing above is true

Let's explore it with an example using W3Schools.

Suppose you have a simple quiz program that asks the user to input their name and age. Based on this information, you want to print out a personalized message. You can use if-elif-else statement to achieve this:

name = input("Enter your name: ")
age = int(input("Enter your age: "))
if age < 18:
print(f"Hello {name}, you are still young!")
elif age >= 65:
print(f"Hi {name}, you are getting older!")
else:
print(f"Hey {name}, you're an adult now!")

In this example, the program asks for the user's name and age. It then checks if the age is less than 18 (using age < 18). If true, it prints out a message saying the person is still young.

If the age is not less than 18, it checks if the age is greater than or equal to 65 (using age >= 65). If true, it prints out a message saying the person is getting older.

If neither of these conditions are met, it means the age is between 18 and 64, so it prints out a message saying the person is an adult now!

Here's how this statement works:

The program starts by executing the if condition. If the if condition evaluates to True (i.e., age < 18), it executes the code inside that block. If not, it moves on to the elif condition and checks if age >= 65. If this condition is True, it executes the code inside that block. If neither of these conditions are met (i.e., age is between 18 and 64), it falls through to the else block and executes the code there.

W3Schools has a great section on Python if, elif, and else statements, with examples and explanations. I hope this example helps illustrate how you can use these statements in your own projects!

The if-elif-else statement in Python is used for making decisions based on conditions. It's a way of executing different blocks of code depending on the outcome of certain conditions.

Here's an example from W3Schools:

x = 10
if x > 5:
print("x is greater than 5")
elif x == 5:
print("x is equal to 5")
else:
print("x is less than or equal to 4")

Let's break this code down:

x = 10: This line assigns the value 10 to the variable x. if x > 5:: This is a conditional statement that checks if the value of x is greater than 5. If it is, then the code inside the if block will be executed. print("x is greater than 5"): This line prints out the message "x is greater than 5" to the console. elif x == 5:: If the condition in step 2 is not met, then this elif statement checks if the value of x is equal to 5. If it is, then the code inside this block will be executed. print("x is equal to 5"): This line prints out the message "x is equal to 5" to the console. else:: If neither of the conditions in steps 2 or 4 are met, then this else block is executed. print("x is less than or equal to 4"): This line prints out the message "x is less than or equal to 4" to the console.

So, when we run this code with the value 10 assigned to x, the output will be:

x is greater than 5

Because 10 is indeed greater than 5. If we change the value of x to 5, then the output will be:

x is equal to 5

And if we change the value of x to something less than or equal to 4, like 3, then the output will be:

x is less than or equal to 4

This demonstrates how the if-elif-else statement can be used to make decisions based on conditions and execute different blocks of code accordingly.
