What is elif in Python example?

I'm happy to help you with your question!

In Python, elif stands for "else if", which is a conditional statement used to test another condition after an earlier condition has been tested and found false.

The general syntax of elif in Python is as follows:

if condition1:
code block
elif condition2:
code block

Let's consider an example to better understand how elif works:

Suppose we want a program that checks if a person is eligible for a loan. The eligibility criteria are as follows:

Here's an example code using elif:

age = 22
income = 25000
if age >= 18:
if income > 30000:
print("You are eligible for a loan.")
else:
print("Your income is too low. You may need to save more or improve your credit score.")
elif income > 30000:
print("You do not meet the age criteria, but your income is sufficient. You still need to be at least 18 years old to apply for a loan.")
else:
print("You do not meet either the age or income criteria.")

In this example:

The elif clause checks if the condition after the comma is true. In this case, it's income > 30000. If this condition is true, the code within that block will execute.

In summary, elif allows you to test multiple conditions and execute different code blocks based on whether those conditions are true or false.

If-else statement in Python example

I'm glad you asked! Here's an example of using if-else statements in Python:

# Example of using if-else statements in Python
Define a variable for user input age
age = int(input("Enter your age: "))
Use if-else statement to check the age and print out different messages
if age < 18:
print("You are still young! You are", age, "years old.")
elif 18 <= age < 65:
print("You are an adult now! You are", age, "years old.")
else:
print("You are a senior! You are", age, "years old.")
Now, let's try to use if-else statement for more complex logic
score = int(input("Enter your score (out of 100): "))
if score < 60:
grade = "F"
elif 60 <= score < 70:
grade = "D"
elif 70 <= score < 80:
grade = "C"
elif 80 <= score < 90:
grade = "B"
else:
grade = "A"
print("Your grade is:", grade)
Another example using if-else statement with multiple conditions
x, y = int(input("Enter x: ")), int(input("Enter y: "))
if x > y and x % 2 == 0 or y % 3 == 1:
print("Both conditions are true!")
elif x < y and y % 4 == 2:
print("First condition is false, second condition is true!")
else:
print("None of the conditions are true!")

In this example, we use if-else statements to check different age ranges and print out corresponding messages. We also show more complex examples where if-else statements are used with multiple conditions.

Here's a summary of how to use if-else statements in Python:

I hope you find this example helpful!
