我的简单数学测验有错误,表明B变量未定义。我尝试将它定义为stringvar但仍然有错误。我应该在哪里定义变量?并且我的总计是使其继续计算结果框中的最后一个接口的正确方法。可以有人显示解决它的示例。
import Tkinter
import tkMessageBox
#easybox1
EasyBox1 = Tkinter.Tk()
EasyBox1.geometry("250x200")
EasyBox1.title("Quesion 1")
Tkinter.Label (EasyBox1, text="answer:").pack()
answr1 = Tkinter.Entry (EasyBox1)
answr1.pack()
LabelName2 = Tkinter.Label (EasyBox1, text="State the number of edges in a cube")
LabelName2.grid(row=1,column=0)
LabelName2.pack()

total = 0

tkMessageBox.showerror('no answer')

如果你想将答案与字符串'B'或'b'进行比较,只需引用它们
答案 1 :(得分:3)
只需在"b"
和"B"
附近加上引号:
def mark():
total = 0
if not answr2.get():
tkMessageBox.showerror('no answer')
elif answr2.get() in ["B", "b"]:
total = total + 1
EasyBox1.withdraw()
ResultBox.deiconify()
else:
total = total
EasyBox1.withdraw()
ResultBox.deiconify()
此外,与or "b"
的比较现在不起作用,您可以将其更改为
if answr2.get() in ["B", "b"]:
或
if answr2.get().upper() == "B":
