How can I write a basic if-then-else statement in a single line in Python?

Hey everyone! I’m trying to streamline some code I’m working on and I’ve heard about using a condensed version of if-then-else statements in Python. I know there’s a way to do it in a single line, but I’m having a bit of trouble figuring out the syntax. Can anyone share how I can write a basic if-then-else statement in one line? Would love to see some examples too! Thanks!

    1. Python If-Then-Else in One Line

      Streamlining Your Python Code

      Hey there! It’s great that you’re looking to streamline your code. In Python, you can use a condensed version of if-then-else statements called the ternary operator. The basic syntax looks like this:

      value_if_true if condition else value_if_false

      Here are a couple of examples to help you understand how it works:

      • Example 1:
        • result = "Even" if number % 2 == 0 else "Odd"

        This code checks if a number is even or odd and assigns the result to the variable result.

      • Example 2:
        • max_value = a if a > b else b

        In this example, max_value will store the greater of two variables, a and b.

      I hope this helps you streamline your code! Happy coding!




    2. Python If-Then-Else in One Line

      Using If-Then-Else in One Line in Python

      Hi there! If you want to write a basic if-then-else statement in one line in Python, you can use what’s called a ternary operator. The syntax looks like this:

      value_if_true if condition else value_if_false

      Here’s a simple example:

      age = 18
result = "Adult" if age >= 18 else "Minor"
print(result)  # This will print "Adult"

      In this example, if age is 18 or more, result will be “Adult”. If it’s less than 18, it will be “Minor”.

      You can use this format to make your code shorter and cleaner. Hope this helps!



    3. In Python, you can condense an if-then-else statement into a single line using the ternary conditional operator. The general syntax is: value_if_true if condition else value_if_false. This allows you to evaluate a condition and return one of two values based on whether the condition is true or false, all within a single line of code. For example, if you want to assign a variable based on a numeric comparison, you could use the expression: result = "High" if score > 70 else "Low". Here, result will be set to “High” if score is greater than 70, otherwise it will be set to “Low”.

      Another practical example would be determining whether a user is eligible for a discount based on their age: discount = "10%" if age < 18 else "0%". In this case, discount will receive the value "10%" if the user's age is less than 18, and "0%" if not. This concise syntax is especially useful for simple conditions and can make your code cleaner and easier to read, which is a key aspect when streamlining your code.
