Python 如何创建大量标签和条目小部件，并在Tkinter with loop中从中获取数据

我需要使用Tkinker创建几个标签和输入字段，它们都是相同的，唯一的区别是标签中的文本，我可以在列表中看到。 这就是问题看起来的样子，虽然用一种简单的方法来解决，但我想更聪明地解决它，使用某种循环，这样我就可以扩展它

from tkinter import *

root = Tk()

question1 = Label(root, text="Please give data number one")
question1.grid(row=1, column=0)
field1 = Entry(root)
field1.grid(row=1, column=1)

question2 = Label(root, text="Please give data number two")
question2.grid(row=2, column=0)
field2 = Entry(root)
field2.grid(row=2, column=1)

question3 = Label(root, text="Please give data number three")
question3.grid(row=3, column=0)
field3 = Entry(root)
field3.grid(row=3, column=1)

question4 = Label(root, text="Please give data number four")
question4.grid(row=4, column=0)
field4 = Entry(root)
field4.grid(row=4, column=1)

data1 = field1.get()
data2 = field2.get()
data3 = field3.get()
data4 = field4.get()

root.mainloop()

我考虑过类似的事情，但我不知道如何从Enter小部件中获取值

from tkinter import *

root = Tk()

questions = ["Please give data number one",
"Please give data number two"
"Please give data number three"
"Please give data number four"
]

for question in enumerate(questions):
    ask = Label(root, text=question[1])
    ask.grid(row=(question[0] + 1), column=0)
    field = Entry(root)
    field.grid(row=(question[0] + 1), column=1)

root.mainloop()

你需要做两件事： 首先保留对小部件的引用，然后使用get方法获取字符串

例如：

self.entry = Entry(...)

…一些代码

print("the text is", self.entry.get())

示例获取条目：

class InputPage(Frame):
    def __init__(self, parent, controller):
        Frame.__init__(self,parent)        

        label =  Label(self, text="Please give data number four")
        label.grid(row=0, column=0, sticky ='n', columnspan =2)

        # i brought your variable in the class for example sake 

        namesInput = ["First:", "second:", "Third:", "Fourth:", "Fifth:"]

        self.entryWidgets = [] # we want to call this in another function so we assign it as self.variableName

        labelWidgets = []

        #LOOP TO CREATE WIDGETS
        for i in range(0, len(namesInput)):
            labelWidgets.append(Label(self, text = namesInput[i]))
            self.entryWidgets.append(Entry(self))
            labelWidgets[-1].grid(row= i+1, column =0, sticky='e')
            self.entryWidgets[-1].grid(row= i+1, column = 1, sticky='w')

        submit = Button(self, text = "Submit", command = self.getEntries)
        submit.grid(row = 6, column =0, columnspan =2)

    def getEntries(self):
        results = []

        for x in self.entryWidgets: # i.e for each widget in entryWidget list
            results.append(x.get())
        print(results)

对不起，我不知道你的意思是什么，也不知道你发送的代码如何帮助我，也许我对这种方式的理解太糟糕了。你想把数组中的每个元素分配给for循环中的标签吗？是的，这是可行的，但我不知道在用户填充条目小部件后如何从条目小部件中获取数据。field.get函数给出了我从第4位开始的最后一个值widget@katek1094请在问题：results.appendx.get printresults中为x测试：result=[]我编辑了关于如何创建小部件和获取实体的循环的答案。对不起，我不知道你的意思，以及你发送的代码如何帮助我，也许我这样理解太糟糕了。是否要将数组中的每个元素分配给for循环中的标签？是的，这是可行的，但我不知道在用户填充条目小部件后如何从条目小部件中获取数据。field.get函数给出了我从第4位开始的最后一个值widget@katek1094请在questions:results.appendx.get printresults中为x测试：result=[]我编辑了如何循环创建小部件和获取实体的答案。
