a = 1 b = 2 c = a + b print(c) Each of the four statements is written in a separate line in a code editor—this is the normal procedure. However, we can extend it over to multiple lines using the line continuation character (\). See the article below. The value in itself is a valid expression and so is a variable.

In its simplest form, it looks like this: In the form shown above: 1. How to style multi-line conditions in 'if' statements in Python? Normally each statement is written on separate physical line in editor. Run the code and check if the one-liner does the same as the original code! In this case, you can use the semicolon as a separator between the statements: Let’s do some practice testing to learn and improve your Python skills: Exercise: one-linerize the given code! We can use nested if statements for situations where we want to check for a secondary condition if the first condition executes as true. 99% of Finxter material is completely free. Python allows us to write an entire if statement on one line.
