Python if Statement<\/h1>\n

The if<\/code> statement in Python is a control statement that allows you to execute code based on a condition. When the condition is true, the specified block of code runs, and when false, another block runs, or no operation is performed. In Python, the if<\/code> statement is structured as follows:<\/p>\n

Basic Structure:<\/h2>\n
if condition:\n    code to execute\n    <\/code><\/pre>\n
Example:<\/h2>\n
age = 18\n\nif age >= 18:\n    print(\"You are an adult.\")\n    <\/code><\/pre>\n
In the above code, since age<\/code> is 18, the condition age >= 18<\/code> evaluates to true, and print(\"You are an adult.\")<\/code> is executed. If the condition is false, this block will be ignored.<\/p>\n
Using else<\/code><\/h2>\n
else<\/code> lets you specify code to run when the condition is false.<\/p>\n
age = 16\n\nif age >= 18:\n    print(\"You are an adult.\")\nelse:\n    print(\"You are a minor.\")\n    <\/code><\/pre>\n
Here, since age<\/code> is 16, the condition is false, and the else<\/code> block runs.<\/p>\n
Using elif<\/code><\/h2>\n
Sometimes you need to check multiple conditions. You can use elif<\/code> to check additional conditions.<\/p>\n
age = 17\n\nif age >= 18:\n    print(\"You are an adult.\")\nelif age >= 13:\n    print(\"You are a teenager.\")\nelse:\n    print(\"You are a child.\")\n    <\/code><\/pre>\n
In this code, since age<\/code> is 17, the first condition is false, but the second elif<\/code> condition is true, so “You are a teenager.” is printed.<\/p>\n
Nested if Statements<\/h2>\n
You can also use an if<\/code> statement within another if<\/code> statement. This is called a nested if<\/code> statement.<\/p>\n
age = 20\nis_student = True\n\nif age >= 18:\n    if is_student:\n        print(\"You are an adult and a student.\")\n    else:\n        print(\"You are an adult but not a student.\")\n    <\/code><\/pre>\n
Here, since the condition age >= 18<\/code> is true, it enters the first if<\/code> block, and since the if is_student:<\/code> condition is also true, “You are an adult and a student.” is printed.<\/p>\n
Comparison Operators and Logical Operators<\/h2>\n
In the if<\/code> statement, you can use various comparison and logical operators.<\/p>\n
