None is an object that represents the absence of a value. If we don’t use the return statement, by default Greet_user(“John”, “Smith”)Keyword arguments(Ĭalculate_total(order= 50, shipping= 5, tax=0) Keyword arguments: position doesn’t matter - we prefix them with the parameter Positional arguments: their position (order) matters Parameters are placeholders for the data we can pass to functions. If there are bugs, it’s easier to find bugs in a We use functions to break up our code into small chunks. We can useĬustomer(“type”, “silver”) # returns “silver”(Ĭustomer = “new name”( Functions. We can use strings or numbers to define keys. We use dictionaries to store key/value pairs. Is_night = not is_day Comparison operators. If has_high_income and has_good_credit: ( ** # exponentiation - x ** y = x to the power of y To check if a string contains a character (or a sequence of characters), we use the inĬontains = ‘Python’ in course Arithmetic Operations. Result into an integer by calling the built-in int() function. The input() function always returns data as a string. We can receive input from the user by calling the input() function.
