the number of passed arguments will not be known until run-time. To make matters even worse, you won't know the types and sizes of arguments until run-time as well. Needless to say, there is no obvious way to make the C compiler generate code for a function ...
Here, *args captures the positional arguments, and **kwargs captures the keyword arguments. This combination makes the function incredibly flexible, accommodating various inputs. Developers can use this approach when designing functions that require adaptability to different input scenarios, providing a c...
Variable-length arguments, varargs for short, are arguments that can take an unspecified amount of input. When these are used, the programmer does not need to wrap the data in a list or an alternative sequence. In Python, varargs are defined using the *args syntax. Let's reimplement our ...

15.5How can I write a function that takes a format string and a variable number of arguments, likeprintf, and passes them toprintfto do most of the work? 15.6How can I write a function analogous toscanf, i.e. that accepts similar arguments, and callsscanfto do most of the work?
