变量不起作用......或者我错过了什么？

Question

我正在尝试对docx文件进行一些编辑...将数字转换成字母(即如果变量等于01 ='one',等于02 ='two',依此类推,但是用西班牙语).问题是变量f_dia_nom不起作用......它甚至不打印任何东西......我做错了什么？还是我错过了什么？

查看python的'全局范围'规则.一般来说,尽量避免使用全局变量(如果只是为了避免这些错误)

在nombre_dia()中:

f_dia_nom = "Un" 

或者任何其他任务,python编译器将该数字创建为nombre_dia函数的LOCAL.

修改你的函数以将f_dia_nom声明为全局:

def nombra_dia():
   global f_dia_nom

   ...

它将使nombre_dia将f_dia_nom视为全局
