Python 3.x Python3.x:TypeError:';StringVar';对象不可编辑&;属性错误:';StringVar';对象没有属性';项目';
当我尝试这个的时候Python 3.x Python3.x:TypeError:';StringVar';对象不可编辑&;属性错误:';StringVar';对象没有属性';项目';,python-3.x,user-interface,tkinter,Python 3.x,User Interface,Tkinter,当我尝试这个的时候 archivist_dates=[ "Thur,19th of October", "Fri,20th of October", "Sat,21th of October", "Sun,22th of October", "Mon,23th of October", "Tue,24th of October", "Wed,25th of October", "Latest"]# the list of dates
archivist_dates=[

variable=StringVar()
variable.set(archivist_dates[0])
list_menu=OptionMenu(archivist_gui,variable,*archivist_dates)

extracted',value=2,font=('Times',24),command=htmlgenerator)
archive_button=Radiobutton(archivist_buttons,variable,text='Archive the
latest news',value=3,font=('Tikmes',24),command=download)
出现如下错误声明:
_cnfmerge:由于“StringVar”对象不可回溯而导致的回退(最近一次调用last):文件
“/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/init.py”,
第103行,in_cnfmerge
cnf.update(c)TypeError:“StringVar”对象不可编辑
在处理上述异常期间,发生了另一个异常:
回溯(最近一次调用上次):文件
“/Volumes/study/en01/ifb104/ass2/internetrachive/news\u archivist.py”,
第798行,输入
提取按钮=单选按钮(归档按钮、变量、文本=”提取
存档新闻',值=1,字体=('Times',24),命令=extracts)文件 “/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/init.py”, 第2978行,在init 控件。init(self,master,'radiobutton',cnf,kw)文件“/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/init.py”, 第2284行,在init cnf=_cnfmerge((cnf,kw))文件“/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/init.py”, 第106行,in_cnfmerge 对于c.items()中的k,v:AttributeError:'StringVar'对象没有属性'items' 有人能解释一下错误并帮我修复吗?问题在这里:
extract_button=Radiobutton(archivist_buttons,variable,text='Extract news from archive', value=1, font=('Times',24),command=extracts)
您分配的变量
不正确,单选按钮
正在查找不存在的变量['items']
,因为StringVar()
没有名为'items'
的属性
相反,您应该将StringVar()
指定为variable=variable
。这意味着整个通话将是:
extract_button=Radiobutton(archivist_buttons,variable=variable,text='Extract news from archive', value=1, font=('Times',24),command=extracts)
