An if-else statement is a common conditional statement. Learn when and how to write an if-else statement.
- [Instructor] An if-else statement is used … to instruct the computer to perform a certain action … if a certain condition is met … and a different action if that condition is not met. … For example, say you want a function … that takes two numbers as inputs … and these numbers can be either integers … or floating point numbers … and the function returns the minimum of these two numbers. … You would do something like this. … I'll start with the def keyword … because I'm defining a function … followed by the name of the function, … I'll name this function minimum, … followed by parenthesis x, y … and x and y will be generic representations of the inputs … that minimum takes in, … followed by a colon. … I hit Enter to get to the next line. … And after the indent, … I'll begin writing my if-else statement. … I start with the if keyword … followed by the condition that I want to check. … In this case, I want to check if x is less than y … so I say x less than y followed by a colon. … And on the next line after the indent, …
