![]() ![]() ![]() When the above code is executed, it returns the same result as it was with the required arguments: "Hi there" and in a new line number: "999". Print (value) # This prints a passed value into this function You can also make keyword calls to the printme() function in the following ways: This allows you to skip arguments or place them out of order because the Python interpreter is able to use the keywords provided to match the values with parameters. When you use keyword arguments in a function call, the caller identifies the arguments by the parameter name. Keyword arguments are related to the function calls. When the above code is executed, it prints: "Hi there". Print (str) # This prints a passed string into this function ![]() Here, the number of arguments in the function call should match exactly with the function definition. Required arguments are the arguments passed to a function in correct positional order. The above function takes addition as an input parameter and prints it on a standard screen when we call this example() function. You always must use return with the return value, otherwise, it will return none. A return statement with no arguments is the same as a return None.īy default, function parameters have a positional behavior and you need to inform them in the same order that they were defined. The statement return exits a function, optionally passing back an expression to the caller.The code block within every function starts with a colon (:) and is indented.You can also define parameters inside these parentheses, for example: " def DoSomething(y, x):". Any input parameters or arguments should be placed within these parentheses.Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ), example: " def DoSomething():".Here are simple rules to define Python function: You can define functions to provide the required functionality. These functions are called user-defined functions and you can create your own functions. Functions provide better modularity for applications and a high degree of code reusing. A function is a block of organized, reusable code that is used to perform a single, related action. ![]()
