What is elif in Python w3schools?

I apologize for the mistake earlier. Here's a detailed explanation of elif in Python, as requested:

Elif stands for "else if", which is used to execute a block of code when an if statement evaluates to False and another condition (specified by the elif clause) is True.

The syntax for using elif in Python is:

if condition1:
code to be executed

elif condition2:

code to be executed

Here, if condition1 is True, then the block of code following it will be executed. If condition1 is False, Python checks the second condition (condition2). If this is also False, the entire if-elif statement returns an error. However, if condition2 is True, then the block of code following it will be executed.

You can have multiple elif conditions in a single if statement. For example:

if condition1:

code to be executed

elif condition2:

code to be executed

elif condition3:

code to be executed

In this case, the code will execute the first block if condition1 is True. If condition1 is False, Python checks the second condition (condition2). If that's also False, it then checks the third condition (condition3). This process continues until a condition evaluates to True.

Here are some examples of using elif in Python:

Example 1: Simple if-elif

x = 5

if x < 10:

print("x is less than 10")

elif x == 5:

print("x is equal to 5")

In this example, since x is indeed equal to 5, the second condition will be evaluated as True and the code following it will be executed.

Example 2: Multiple elif conditions

age = 30

if age < 18:

print("You're a minor")

elif age >= 65:

print("You're a senior citizen")

elif age < 30:

print("You're in your prime")

Here, since age is 30, the third condition will be evaluated as True and the code following it will be executed.

Example 3: Using elif with else

x = 15

if x > 10:

print("x is greater than 10")

elif x == 5:

print("x is equal to 5")

else:

print("x is less than or equal to 10")

In this example, since x is indeed greater than 10, the first condition will be evaluated as True and the code following it will be executed.

I hope this detailed explanation helps you understand how to use elif in Python!

Python elif w3schools example

I'm happy to help with your query!

Python's elif statement is a conditional statement that allows you to check multiple conditions and perform different actions based on the result. It stands for "else if" and works similar to an if-else block.

Here's an example from W3Schools, which demonstrates the usage of elif:

x = 5

if x > 10:

print("x is greater than 10")

elif x == 5:

print("x is equal to 5")

elif x < 0:

print("x is less than 0")

In this example, we have an if statement that checks if the value of x is greater than 10. If it's not, the code will move on to the next condition in the chain.

The first elif statement checks if x is equal to 5. If it is, it prints out a message saying so.

If x isn't 5 either, it moves on to the last condition in the chain, which checks if x is less than 0. If that's true, it will print out another message.

This way, you can check multiple conditions and perform different actions based on the result. It's a very useful tool for decision-making in your programs!
