Understanding the if Statement
The if statement is one of the fundamental building blocks in Python programming. It allows developers to execute specific blocks of code based on certain conditions. This means if a certain condition evaluates to true, the code inside the if statement runs; if not, it can either do nothing or execute an alternative code block with an else statement.
In Python, the syntax for an if statement is straightforward. It begins with the keyword if, followed by a condition that is evaluated, and concludes with a colon. The code block that follows the condition must be indented to be recognized as part of the if statement. Here’s a simple example:
age = 18
if age >= 18:
print('You are an adult.')In this example, if the variable age is greater than or equal to 18, the program will output You are an adult.. If the condition is not met, nothing will happen.
Using Conditional Expressions
Conditional statements can also lead to the use of expressions termed as conditional expressions, or more commonly known as
