I Googled for a solution for the problem and discovered this question, and I found in IPython you can use inspect.getsource to get functions defined in the interpreter. But you can't use it to get definitions of functions defined interactively in the plain Python shell (i.e. Python.exe)....

查阅Python manual有如下的说法: Default parameter values are evaluated when the function definition is executed. This means that the expression is evaluated once, when the function is defined, and that that same “pre-computed” value is used for each call. This is especially important to understa...
In fact function definitions are also ‘statements’ that are ‘executed’; the execution of a module-level function definition enters the function nameinthe module’sglobalsymbol table.#事实上函数定义也是“被执行”的语句,模块级别函数定义的执行将函数名放入模块全局名称空间表,用globals()可以查看 3....
1. The function code block starts with the def keyword, followed by the function identifier name and parentheses ().2、函数内容以冒号起始,并且缩进。2. The function content starts with a colon and is indented.3、函数的第一行语句可以选择性地使用文档字符串—用于存放函数说明。3. The first line...
The definition of a dictionary is analogous to that of a mapping in mathematics. In this case, a dict is a mapping of K (the set of keys) to V (the values) - but not vice versa. If you dereference a dict, you expect to get exactly one value returned. But, it is perfectly legal...
采用requests.get()方法,请求网页,如果成功访问,则得到的是网页的所有字符串文本。这就是请求过程。 def getHTMLtext(url): """请求获得网页内容""" try: r = requests.get(url, timeout = 30) r.raise_for_status() r.encoding = r.apparent_encoding print("成功访问") return r.text except: print...
