In [7]: p=['kzc',18]In [8]: '{0[0]},{0[1]}'.format(p)Out[8]: 'kzc,18' 有了这些便捷的“映射”方式,我们就有了偷懒利器。基本的python知识告诉我们,list和tuple可以通过“打散”成普通参数给函数,而dict可以打散成关键字参数给函数(通过和*)。所以可以轻松的传个list/tuple/dict给format函数。

The join function in python is a built-in method that allows us to join the elements of a list or tuple into a single string.
5、收集参数:传递任意数量的实参,使用 ' *形参名' 代表该参数,该参数所接受的实参会组成一个元组Tuple 1def youname(first_name, *last_names): 2print(type(last_names)) 3forlast_nameinlast_names: # last_names接收实参后形成元组,遍历出其中的值做后续操作 ...
