    The if statement in Python is used to execute a block of code only when a specified condition evaluates to True. It’s a fundamental control structure for decision-making in programs.

    Example:

    score = 85

    if score >= 90:
    print("Grade: A")
    elif score >= 75:
    print("Grade: B")
    elif score >= 65:
    print("Grade: C")
    else:
    print("Grade: F")
    Cóipeáilte!

    In this example, Python checks each condition in order and executes the first block where the condition is True. Since score is 85, it prints "Grade: B".

    Basic Syntax

    if condition:
    # code block
    Cóipeáilte!

    • The condition must be an expression that evaluates to True or False.

    • Indentation defines the code block under if.

    Using if...else

    number = -5

    if number > 0:
    print("Positive")
    else:
    print("Non-positive")
    Cóipeáilte!

    If the if condition is False, the else block runs.

    Using if...elif...else

    temperature = 30

    if temperature > 35:
    print("Hot")
    elif temperature > 20:
    print("Warm")
    else:
    print("Cold")
    Cóipeáilte!

    Only one branch executes, even if multiple conditions are True.

    Multiple Conditions You can combine conditions with logical operators:

    What is a if condition in Python?
    The condition must be an expression that evaluates to True or False using comparison operators or truthiness rules. When the condition is true, Python executes all the indented code under the if statement. When false, Python skips that code entirely. temperature = 75 is_sunny = True has_umbrella = False if temperature > 70:

    Python relies on indentation (whitespace at the beginning of a line) to define scope in the code. Other programming languages often use curly-brackets for this purpose.
