keys(): print 'key=%s,value=%s' %(key,dict2[key]) key=name,value=earth key=port,value=80 你还可以使用迭代器来轻松地访问数据类型对象(sequence-like objects),比如字典和文件。只需要用字典的名字就可以在for循环里遍历字典。 >>> dict2={'name':'earth','port':80} >>> for key in dict...
在Python中没有switch语句。你可以使用if..elif..else语句来完成同样的工作(在某些场合,使用 字典会更加快捷。) 在C/C++中,如果你想要写for (int i = 0; i < 5; i++),那么用Python,你写成for i in range(0,5)。你 会注意到,Python的for循环更加简单、明白、不易出错。
Output can be expressed both in return value and output parameters. If there's only one output, we recommend using the return value. For multiple outputs, you'll have to use output parameters. To produce multiple outputs, use the set() method provided by the azure.functions.Out interface to...
