print(f'String value returned by str_value(10) is {str_value(10)}') Output: Python Return String Python return tuple Sometimes we want to convert a number of variables into atuple. Let’s see how to write a function to return a tuple from a variable number of arguments. def create_t...
The Python return keyword exits a function and instructs Python to continue executing the main program. The return keyword can send a value back to the main program. A value could be a string, a tuple, or any other object. This is useful because it allows us to process data within a ...
In Python, functions are first-class objects. A first-class object is an object that can be assigned to a variable, passed as an argument to a function, or used as a return value in a function. So, you can use a function object as a return value in any return statement. A function...
In your Python function code, you can set the return value based on whether the function succeeded or failed. For example, you can set the return value to an empty dictionary to indicate success, or to a dictionary containing anis_exceptionproperty set totrueto indicate failure: Copy def main...

In Python, there's no "null" keyword. However, you can use the "None" keyword instead, which implies absence of value, null or "nothing". It can be returned from a function in any of the following ways: By returning None explicitly; By returning an empty return; By returning nothing...
for element in iterable: if element: return True return False ascii(object) 类似repr(),返回一个包含对象的可打印表示的字符串,但使用\x,\u或\U转义符转义由repr()返回的字符串中的非ASCII字符。这会生成一个类似于 Python 2 中 repr()返回的字符串。
5. Python Function Unknown Number of Parameters NOTE: If there are, say 4 parameters in a function and a default value is defined for the 2nd one, then 3rd and 4th parameter should also be assigned a default value. If the number of parameters a function should expect is unknown, then *...
