Python elseif statement

What is elseif statement?

The elif announcement is used together with the if statement to check additional situations after the preliminary if condition. It stands for "else if."

Basic if-elif-else statement:

The program first tests if x > 10. If this condition is real, it executes the corresponding block. If no longer, it actions to the next condition, x == 10. If this situation is real, it executes its block. If none of the situations is genuine, the block below else is completed.

                                  
                                    x = 10

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

Multiple elif statements:

The program tests multiple situations sequentially, and the primary real condition encountered triggers the execution of its corresponding block.

                                  
                                    day = "Wednesday"

if day == "Monday":
    print("It's the start of the week")
elif day == "Wednesday":
    print("It's the middle of the week")
elif day == "Friday":
    print("It's the end of the week")
else:
    print("It's some other day")

Nested if-elif-else statements:

You can nest if-elif-else statements interior each other to create extra complicated conditions. However, in lots of cases, the usage of nested systems can be averted through restructuring the situations.

                                      
                                        grade = 75

if grade >= 90:
    print("A")
elif grade >= 80:
    print("B")
else:
    if grade >= 70:
        print("C")
    else:
        print("F")

Practical Example:

The application assessments the temperature and prints a message primarily based on whether it is warm, moderate, or cold.

                                      
                                        temperature = 28

if temperature >= 30:
    print("It's hot!")
elif 20 <= temperature < 30:
    print("It's moderate.")
else:
    print("It's cold.")

The elif statement is beneficial when you need to check a couple of conditions in a controlled collection. It gives a clean and organized manner to address complicated selection-making in your Python applications.
