Tkinter界面：

Question

我制作了一个程序，用户在其中输入目标号码和其他4个数字作为目标号码。现在，我很难将我的tkinter接口集成到我的代码中。所以我希望有人能帮助我

Tkinter界面：

window = Tk()
window.title("target number solution")
Label(window,image='', bg="white") .grid(row=0, column=0, sticky=W)
Label(window, text="Enter target number:",bg="black", fg="white", font="none 12 bold").grid(row=1, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=2, column=0, sticky=N)


Label(window, text="Enter first number:",bg="black", fg="white", font="none 12 bold").grid(row=4, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=5, column=0, sticky=N)


Label(window, text="Enter second number:",bg="black", fg="white", font="none 12 bold").grid(row=6, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=7, column=0, sticky=N)


Label(window, text="Enter third number:",bg="black", fg="white", font="none 12 bold").grid(row=8, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=9, column=0, sticky=N)


Label(window, text="Enter fourth number:",bg="black", fg="white", font="none 12 bold").grid(row=10, column=0, sticky=N)
textentry = Entry(window, width=20, bg="white")
textentry.grid(row=11, column=0, sticky=N)


Button(window, text="Solve", width=6, command=solver).grid(row=12, column=0, sticky=N)
output = Text(window, width=60, height=10, wrap=WORD, background="white")
output.grid(row=13, column=0, columnspan=1, sticky=N)


window.mainloop()

这是需要与tkinter接口链接的代码：

from itertools import permutations,combinations_with_replacement
numbers   = []
target    = int(input())
operators = ["+","-","*","/"]
groups    = ['X+X+X+X', 'X+X+(X+X)', 'X+(X+X)+X', '(X+X+X)+X', '(X+X)+X+X', 'X+(X+X+X)', '((X+X)+X)+X', 'X+(X+(X+X))', 'X+((X+X)+X)', '(X+X)+(X+X)', '(X+(X+X))+X']
seen      = set()
for values in permutations(numbers,len(numbers)):
    for operCombo in combinations_with_replacement(operators,len(numbers)-1):
        for oper in permutations(operCombo,len(numbers)-1):
            formulaKey = "".join(oper+values)
            if formulaKey in seen: continue # ignore variations on parentheses alone
            for pattern in groups:
                formula = "".join(o+p for o,p in zip([""]+list(oper), pattern.split("+")))
                formula = "".join(v+p for v,p in zip([""]+list(values),formula.split("X")))
                try:
                    if eval(formula) == target:
                        global Answer
                        Answer = formula,"=",target
                        print(formula,"=",target)
                        seen.add(formulaKey)
                        break
                except: pass

所有建议都会被应用

Answer 1

您可以将每个数字的值存储在单独的IntVar变量中，然后在solver函数中获取这些变量的值，并执行第二个代码中的所有操作。应该使用包含用于创建小部件并运行solver代码的函数的类对代码进行模块化。要了解有关Tkinter中基于类的声明的更多信息，请阅读this。

from tkinter import Tk, Frame, Label, Button, IntVar, Entry, Text, W, N, WORD, INSERT

        self.create_widgets() 


    def create_widgets(self):

        self.target_num = IntVar()
        self.num1 = IntVar()
        self.num2 = IntVar()
        self.num3 = IntVar()
        self.num4 = IntVar()       
        # self.title("target number solution")

        Label(self,image='', bg="white").grid(row=0, column=0, sticky=W)

        self.textentry1 = Entry(self, textvariable=self.target_num, width=20, bg="white")
        self.textentry1.grid(row=2, column=0, sticky=N)

                        except: pass

root = Tk()
app = Application(master=root)
app.master.title("target number solution")
app.mainloop()

Answer 2

您可以更改/尝试的几件事：

保持“ Entry”变量唯一。然后使用.get（）命令提取每个数字。
在Button的命令选项中使用lambda，如下所示：

command = lambda：solver（num1，num2，num3，num4）
如果要显示从“求解器”返回的数字，请在tkinter窗口中网格化一个Label。然后使用Label.config(text="Your number here")将其显示在tkinter窗口中
