Else and Elif Statement

Elif Statement

The elif keyword allows you to check multiple expressions for True and execute a block of code as soon as one of the conditions is true.

Example:

python
1
2
3
4
5
6
a = 33
b = 33
if b > a:
    print("b is greater than a")
elif a == b:
    print("a and b are equal")

In this example, since a and b are equal, the output will be:

1
a and b are equal

Else Statement

The else keyword is used to catch anything that isn't caught by the preceding conditions.

Example:

python
1
2
3
4
5
6
7
8
a = 200
b = 33
if b > a:
    print("b is greater than a")
elif a == b:
    print("a and b are equal")
else:
    print("a is greater than b")

Here, since a is greater than b, the output will be:

1
a is greater than b

Else Without Elif

You can have an else statement without an elif.

Example:

python
1
2
3
4
5
6
a = 200
b = 33
if b > a:
    print("b is greater than a")
else:
    print("b is not greater than a")

Short Hand If

If you have only one statement to execute, you can write it on the same line as the if statement.

Example:

python
1
if a > b: print("a is greater than b")

Short Hand If ... Else

For simple conditions with one statement for if and one for else, you can write it all on the same line using a ternary operator.

Example:

python
1
2
3
a = 2
b = 330
print("A") if a > b else print("B")

Logical Operators

1. And

The and keyword is used to combine conditional statements.

Example:

python
1
2
3
4
5
a = 200
b = 33
c = 500
if a > b and c > a:
    print("Both conditions are True")

2. Or

The or keyword is used to check if at least one of the conditions is true.

Example:

python
1
2
if a > b or a > c:
    print("At least one of the conditions is True")

3. Not

The not keyword reverses the result of the conditional statement.

Example:

python
1
2
if not a > b:
    print("a is NOT greater than b")

Frequently Asked Questions

The if, elif, and else statements are used for decision-making in Python. They allow you to test multiple conditions and execute different blocks of code based on those conditions.

The if-else statement is used to execute one block of code if a condition is true and another block if the condition is false.

No, if-else is not a function. It is a control structure used to execute different code based on conditions.

In Python, else if is called elif, which stands for "else if."

elif is short for "else if" and allows you to check multiple conditions. It follows an if statement and executes a block of code if its condition is true.

if tests the first condition, elif checks additional conditions if the if condition is false, and else handles the case when none of the conditions are true.

In Python, else if is written as elif and is used to test additional conditions after the if statement.

You can use as many elif statements as needed in Python, but they must be placed between the if and else statements. There is no fixed limit.
