'str'对象没有属性'get'-如何告诉python返回的字符串是字典？

Question

当我尝试获取键的值时，我得到一个“ str”对象没有属性“ get”错误，而键的值又是字典的名称。如何告诉python返回的字符串是字典？choices = ['Country','State','Town']chosen = 'Country'country_color = {'Netherlands':'Red','Sweden':'Brown','Ukraine':'Yellow','China':'Pink','Japan':'Black'}state_color = { .... }town_color = { .... }color_data = {'Country': ['col1','country_color'] ,'State': ['col2','state_color'] ,'Town': ['col3','town_color']}    .....color1 = lambda v: country_color.get(v['col1']) # this workscolor2 = lambda v: country_color.get(v[color_data.get(chosen)[0]]) # this too works  color3 = lambda v: color_data.get(chosen)[1].get(v[color_data.get(chosen)[0]]) # but this doesn't work; error - 'str' object has no attribute 'get'    ....

如果您这样编码：

1. print("Client Name is : {}".format(function).get()) ----错误----

2. 您将收到此错误“ str”对象没有属性“ get”

3. print("Client Name is : {}".format(FNEntry.get())) ----固定----
