Theprint()function prints the specified message to the screen, or other standard output device. The message can be a string, or any other object, the object will be converted into a string before written to the screen. Syntax print(object(s), sep=separator, end=end, file=file, flush=flu...
def example_function(): print("Hello, world!") source_code = inspect.getsource(example_function) print(source_code) 详细描述 inspect模块是Python标准库的一部分,其设计目的是允许开发者检查对象。通过inspect.getsource()函数,我们可以获取一个函数的源代码文本。这在需要理解一个函数的实现细节,或者在没有源...

在filter中会自动的把iterable中的元素传递给function. 然后根据function返回的True或者False来判断是否保留留此项数据 , Iterable: 可迭代对象 def func(i): # 判断奇数 return i % 2 == 1 lst = [1,2,3,4,5,6,7,8,9] l1 = filter(func, lst) #l1是迭代器 print(l1) #<filter object at...
Python中的func通常指的是函数(Function)、一种封装了一组特定功能的代码块、它可以接受输入参数并可能返回一个结果。函数在编程语言中用于增加代码的重用性和模块性,是组织程序结构的一个核心概念。 在Python中,函数是通过关键字def来定义的,后跟函数名和括号内的参数列表。函数体内包含一系列的语句,它们共同完成某个...
