In Python, the assert statement is used to validate whether or not a condition is true, using the syntax: assert If the condition evaluates to True, the program continues executing as if nothing out of the ordinary happened. However, if the condition evaluates to False, the program terminates with an AssertionError. >>> assert True Nothing happens when the code above is executed, since the condition evaluates to […]

In this article, we’ll examine how to print a string without a newline character using Python. In Python, the built-in print function is used to print content to the standard output, which is usually the console. By default, the print function adds a newline character at the end of the printed content, so the next output by the program occurs on the next line. Try running this code to see an example: print(‘Banana’) print(‘pudding.’) Output: Banana pudding. As expected, the […]
