在编程的语境下,函数(function)指的是一个有命名的、执行某个计算的语句序列(sequence of statements)。 在定义一个函数的时候,你需要指定函数的名字和语句序列。 之后,你可以通过这个名字“调用(call)”该函数。 1.函数调用 我们已经看见过一个函数调用(function call)的例子。 >>> type(42) <class 'int'> ...
fn: the function to wrap a user interface (UI) around inputs: the Gradio component(s) to use for the input. The number of components should match the number of arguments in your function. outputs: the Gradio component(s) to use for the output. The number of components should match the...
An argument is the value that is sent to the function when it is called. Number of Arguments By default, a function must be called with the correct number of arguments. Meaning that if your function expects 2 arguments, you have to call the function with 2 arguments, not more, and not...
