Conditional statements allow your program to make decisions. In Python, we use if, else, and elif<\/strong> to execute different blocks of code based on conditions.<\/p>\n\n\n\n

These statements help control the flow of a program.<\/p>\n\n\n\n

1. IF STATEMENT<\/strong><\/h1>\n\n\n\n

The if<\/strong> statement checks a condition.
If the condition is True<\/strong>, the code inside the block runs.<\/p>\n\n\n\n

Syntax:<\/h3>\n\n\n\n
if condition:
    # code to execute<\/pre>\n\n\n\n
Example:<\/h3>\n\n\n\n
age = 18if age >= 18:
    print(\"You are eligible to vote.\")<\/pre>\n\n\n\n
If the condition is true, the message will be printed.<\/p>\n\n\n\n
2. ELSE STATEMENT<\/strong><\/h1>\n\n\n\n
The else<\/strong> statement runs when the condition in the if statement is False<\/strong>.<\/p>\n\n\n\n
Syntax:<\/h3>\n\n\n\n
if condition:
    # code if true
else:
    # code if false<\/pre>\n\n\n\n
Example:<\/h3>\n\n\n\n
age = 16if age >= 18:
    print(\"You are eligible to vote.\")
else:
    print(\"You are not eligible to vote.\")<\/pre>\n\n\n\n
Since the condition is false, the else block runs.<\/p>\n\n\n\n
3. ELIF STATEMENT<\/strong><\/h1>\n\n\n\n
The elif<\/strong> (else if) statement checks multiple conditions.
It is used when you have more than two possible outcomes.<\/p>\n\n\n\n
Syntax:<\/h3>\n\n\n\n
if condition1:
    # code
elif condition2:
    # code
else:
    # code<\/pre>\n\n\n\n
Example:<\/h3>\n\n\n\n
marks = 75if marks >= 90:
    print(\"Grade A\")
elif marks >= 80:
    print(\"Grade B\")
elif marks >= 70:
    print(\"Grade C\")
else:
    print(\"Fail\")<\/pre>\n\n\n\n
The program checks conditions one by one.
When a true condition is found, it executes that block and stops checking further conditions.<\/p>\n\n\n\n
IMPORTANT RULES<\/strong><\/h1>\n\n\n\n
\u2022 Indentation is very important in Python.
\u2022 Use colon (:) after if, elif, and else.
\u2022 Only one else block is allowed.
\u2022 You can use multiple elif blocks.<\/p>\n\n\n\n
NESTED IF STATEMENT<\/strong><\/h1>\n\n\n\n
You can place an if statement inside another if statement.<\/p>\n\n\n\n
Example:<\/h3>\n\n\n\n
age = 20
has_id = Trueif age >= 18:
    if has_id:
        print(\"You can enter.\")
    else:
        print(\"You need an ID.\")
else:
    print(\"You are underage.\")<\/pre>\n\n\n\n
WHY CONDITIONAL STATEMENTS ARE IMPORTANT<\/strong><\/h1>\n\n\n\n
\u2022 They help programs make decisions
\u2022 They control program flow
\u2022 They allow logical problem solving<\/p>\n\n\n\n
Understanding if, else, and elif<\/strong> is essential for building real-world Python applications.<\/p>\n\n\n
