To print a variable with a string in one line, you again include the character f in the same place - right before the quotation marks. Note: The atomic nature of the standard output in Python is a byproduct of the Global Interpreter Lock, which applies locking around bytecode instructions. print() concatenated all four arguments passed to it, and it inserted a single space between them so that you didnt end up with a squashed message like 'My name isjdoeand I am42'. Note: In Python 3, the pass statement can be replaced with the ellipsis () literal to indicate a placeholder: This prevents the interpreter from raising IndentationError due to missing indented block of code.
