deffunc():'''This is self-definedfunctionDo nothing''' pass print func.__doc__ #This is self-definedfunction# #Do nothing 五、模块 模块就是一个包含了所有你定义的函数和变量的文件,模块必须以.py为扩展名。模块可以从其他程序中‘输入’(import)以便利用它的功能。 在python程序中导入其他模块使用...
一样是填空题,命令python3 ok -q hof -u 如果结果是一个函数,填写Function,如果运行会报错填写Error,如果输出为空,填写Nothing 一共有11题,里面有两题对新手来说可能有点绕,如果想不明白可以先运行得到答案,再反向思考原因。 代码语言:javascript 复制 >>>defeven(f):...defodd(x):...ifx<0:...return...
Example 1: BasicifStatement x=10ifx>5:pass# This block will do nothing if x is greater than 5else:print("x is not greater than 5") Output: # If x is greater than 5, there is no output.# If x is 5 or less, the output will be:x is not greater than 5 ...
Sometimes, it’s useful to pass arguments to your decorators. For instance, @do_twice could be extended to a @repeat(num_times) decorator. The number of times to execute the decorated function could then be given as an argument.If you define @repeat, you could do something like this:...
If you’re sure that you want to remove the package because you’ve checked its dependencies and know that nothing else is using it, then you can pass a -y switch to suppress the file list and confirmation dialog: Windows Linux + macOS Windows PowerShell (venv) PS> python -m pip ...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
And it turns out that this “__doc__” is not the only interesting thing on the function—if you do a dir on the function name, a whole slew of interesting things (properly called “attributes”) appear: XML复制 ['__annotations__', '__call__', '__class__', '__closure__',...
But that call is in g() and nothing in a.py or b.py invokes g(). So life is good. But what happens if we attempt to import b.py (without having previously imported a.py, that is): >>> import b Traceback (most recent call last): File "<stdin>", line 1, in <module> ...
