问题描述
好的，这是我收到的错误： AttributeError：‘Des’对象没有‘ASMULT_OUTPUT’属性这就是我正在尝试做的事情。
当我在此框架上时，我正在创建一个文本变量，然后将其发送到Set类。
class upload_csv(Frame):
def __init__(self, master):
self.master = master
self.frame = tk.Frame(self.master, width=250, height=160, bg='white')
self.upload_csv_btn = Button(
self.frame,
text="Add Data Source",
fg="DodgerBlue4",
font=("Graph Type", 15),
height=1, width=20,
borderwidth=2,
relief="groove",
command=self.upload)
self.upload_csv_btn.place(x=10, y=10)
self.frame.pack()
def upload(self):
global text
self.xvalues = []
self.yvalues = []
self.xyvalues = []
self.header = []
filename = filedialog.askopenfilename()
if len(filename) != 0:
print('Selected:', filename)
with open(filename) as file:
csvreader = csv.reader(file)
self.header.append(next(csvreader))
for row in csvreader:
if len(row) == 3:
self.xvalues.append(int(row[0]))
self.yvalues.append(int(row[1]))
self.xyvalues.append(int(row[2]))
text = (
self.header[0][0]+ ": " + str(self.xvalues).replace('[','').replace(']','') +
"
" + self.header[0][1] + ": " + str(self.yvalues).replace('[','').replace(']','') +
"
" + self.header[0][2] + ": " + str(self.xyvalues).replace('[','').replace(']',''))
elif len(row) == 2:
self.xvalues.append(row[0])
self.yvalues.append(row[1])
text = (
self.header[0][0] + ": " + str(self.xvalues).replace('[','').replace(']','') +
"
" + self.header[0][1] + ": " + str(self.yvalues).replace('[','').replace(']',''))
# -------------------------------------------------------------------------
s = Set(text)
s.set_summary()
#-----------------------------------------------------------------------
使用Upload类，我通过调用set类和set_sum方法发送变量。使用这个Set类，我将字符串设置为对象项，然后将其发送到我的DES类。我希望在tk文本框元素上设置此项目作为摘要。我在DES类中收到的文本没有问题，但在尝试修改摘要元素时出现以下错误。 我收到的错误：
Traceback (most recent call last):
File "C:Users***AppDataLocalProgramsPythonPython39lib kinter\__init__.py", line 1892, in __call__
return self.func(*args)
File "C:Users***DocumentsWorkspace******viewupload_csv.py", line 115, in upload
s.set_summary()
File "C:Users***DocumentsWorkspace******viewSet.py", line 14, in set_summary
s.set_summary_text()
File "C:Users***DocumentsWorkspace******view est.py", line 164, in set_summary_text
print(self.summary_output)
AttributeError: 'DES' object has no attribute 'summary_output'
我的Set类：
class Set:
def __init__ (self, summary):
self.summary = summary
def set_summary(self):
print(self.summary)
s = DES(self.summary)
s.set_summary_text()
我的DES类：
class DES(Frame):
def __init__(self, summary):
self.summary = summary
def createFrame(self, master):
self.frame = tk.Frame(master, width=750, height=968,bg='white')
self.summary_output = tk.Text(
self.frame,
height=8,
width=78,
bg="gray95",
borderwidth=2,
relief="groove",
font=("Arial", 12))
self.summary_output.configure(state='disabled')
self.summary_output.place(x=20, y=610)
self.frame.pack()
def set_summary_text(self):
print(self.summary)
print(self.summary_output)
self.summary_output.configure(state='normal')
self.summary_output.delete('1.0', END) # Remote all text
self.summary_output.insert('end',self.summary)
self.summary_output.configure(state='disabled') #Make text widget read only
def main():
global root
root = tk.Tk()
# app = DES(root)
# app = DES.createFrame(root)
s = DES("")
s.createFrame(root)
root.mainloop()
if __name__ == '__main__':
main()
编辑：
所以在尝试回答后，我得到了以下错误，我所做的只是添加了建议：
Exception in Tkinter callback

所以我删除了matploy图，并得到以下错误：
所以可能是图表干扰了？我不确定，我需要这个图表。
推荐答案
类中的summary_output将在
createFrame方法。
您首先从Set.set_summary()中的DES类实例化
方法，然后调用它使用的set_summary_text()方法
summary_output。这是不正确的，因为summary_output尚未定义。
您应该首先调用createFrame()方法来定义
属性，然后调用set_summary_text()以
使用SUMMARY_OUTPUT。
在Set类中这样做：
class Set:
def __init__ (self, summary):
self.summary = summary
def set_summary(self):
global root
print(self.summary)
s = DES(self.summary)
s.createFrame(root)
s.set_summary_text()
或做任何您认为最适合自己的事情，但您应该先定义summary_output，然后再定义print或使用它。
