Question

我的文本文件中包含一些法语动词：

accepter – to accept
adorer – to adore
aimer – to like
annuler – to cancel
apporter – to bring

我有一个Python文件，它将打开该文件，读取它并生成一些有关将这些动词缀合为现在时的随机问题：

from tkinter import *
from tkinter import ttk
from definitions import *
from random import *
def check_conjugation(*args):
    answer_given = str(answer.get())
    correct_answer = present_tense_regular(random_verb, random_pronoun)
    def unaccent(word):
        output = ""
        for x in word:
            english_letters = [y for y in "abcdefghijklmnopqrstuvwxyz"]
            accents = [y for y in "àâáçèéêëìíîòóôùúû"]
            replacements = [y for y in "aaaceeeeiiiooouuu"]
            if x in english_letters:
                output += x
            else:
                for y in range(len(accents)):
                    if x == accents[y]:
                        output += replacements[y]
                        break
        return output     
    unaccented_answer_given = unaccent(answer_given)
    unaccented_correct_answer = unaccent(correct_answer)
    if answer_given == correct_answer:
        decision.set("That is correct, well done!")
        next_button.focus()
        fr_conj_present.bind('<Return>', set_new_pair)
    elif unaccented_answer_given == unaccented_correct_answer:
        decision.set(
"""You have conjugated correctly, well done!
However there were missing accents in your typed answer.
The correct answer was %s""" % correct_answer)
        next_button.focus()
        fr_conj_present.bind('<Return>', set_new_pair)
    else:
        decision.set("That is not correct. Try again.")

    list_of_verbs = []
    with open("french_regular_verbs.txt", 'r') as file:
        for line in file:
            verb = ""
            for letter in line:
                if letter == " ":
                    break
                else:
                    verb += letter
            list_of_verbs.append(verb)
    number_of_verbs = len(list_of_verbs)

def new_pair():
    global random_pronoun
    global random_verb
    random_number = randint(0,number_of_verbs - 1)
    random_verb = list_of_verbs[random_number]
    random_pronoun = ["je", "tu", "il", "vous", "nous", "ils"][randint(0,5)]
    return ((random_verb, random_pronoun))

def set_new_pair(*args):
    question_text.set("Conjugate the verb '%s' to the pronoun '%s' in the present tense:" % new_pair())
    decision.set("")
    conjugation.focus()
    fr_conj_present.bind('<Return>', check_conjugation)


def present_tense_conjugate():
    global mainframe, fr_conj_present, answer, decision, next_button, conjugation, question_text, number_of_verbs, list_of_verbs
    list_of_verbs = []
    with open("french_regular_verbs.txt", 'r') as file:
        for line in file:
            verb = ""
            for letter in line:
                if letter == " ":
                    break
                else:
                    verb += letter
            list_of_verbs.append(verb)
    number_of_verbs = len(list_of_verbs)
    new_pair()
    fr_conj_present = Tk()
    fr_conj_present.title("Conjugating verbs")
    mainframe = ttk.Frame(fr_conj_present, padding="3 3 12 12")
    mainframe.grid(column=0, row=0, sticky=(N, W, E, S))
    fr_conj_present.columnconfigure(0, weight=1)
    fr_conj_present.rowconfigure(0, weight=1)
    answer = StringVar()
    decision = StringVar()
    decision.set("")
    question_text = StringVar()
    question_text.set("Conjugate the verb '%s' to the pronoun '%s' in the present tense:" % new_pair())
    ttk.Label(mainframe, textvariable=question_text).grid(column=1, row=1)
    conjugation = ttk.Entry(mainframe, width=20, textvariable=answer)
    conjugation.grid(column=1, row=2, sticky=(W, E))
    ttk.Label(mainframe, textvariable=decision).grid(column=1,row=3, sticky=(W, E))
    ttk.Button(mainframe, text="Check", command=check_conjugation).grid(column=2,row=2)
    next_button = ttk.Button(mainframe, text="Next", command=set_new_pair)
    next_button.grid(column=2,row=3)
    for child in mainframe.winfo_children():
        child.grid_configure(padx=5, pady=5)
    conjugation.focus()
    fr_conj_present.bind('<Return>', check_conjugation)
    fr_conj_present.mainloop()

我还有另一个程序，应该是调用第一个函数的主窗口：

from tkinter import *
from tkinter import ttk
import french_present_conjugate
def french_appear():
    l2_text.set("You have chosen French. What would you like to do next?")
    b4.grid(row=2, column=2)

master = Tk()
master.title('MRL Languages')
master.geometry("700x500")

l1 = ttk.Label(master, text="Choose a langugage:")
l1.grid(row=1, column=1, pady=20)

b1 = ttk.Button(master, text="French\nFrancais", command=french_appear)
b1.grid(row=2, column=1, sticky=W, padx = 25, pady=5)

b2 = ttk.Button(master, text="German\nDeutsch")
b2.grid(row=3, column=1, sticky=W, padx = 25, pady=5)

b3 = ttk.Button(master, text="Russian\nРусскйи")
b3.grid(row=4, column=1, sticky=W, padx = 25, pady=5)

l2_text = StringVar()
l2_text.set("Please select a language from the left for more options.")
l2 = ttk.Label(master, textvariable=l2_text)
l2.grid(row=1, column=2, padx=25, pady=20)

b4 = ttk.Button(master,
                text="Conjugate verbs to present tense",
                command=french_present_conjugate.present_tense_conjugate)

mainloop()

但是，只要我运行主窗口（上面的代码的第三块）并选择“法语”，然后选择“使动词呈现时态”，它就会打开窗口，但没有任何问题，等等：

Bad

看起来应该像这样：

Good

知道我在做什么错吗？

Answer 1

对于某些奇怪的Tkinter Lable，它不支持textvariable参数，尽管如果我们使用text='Hello'，则它可以完美地工作。

因此，如果您将代码更改为

 txt = "Conjugate the verb '%s' to the pronoun '%s' in the present tense:" % new_pair()
 ttk.Label(mainframe, text=txt).grid(column=1, row=1)

然后标签将在用户界面中可见，我认为您还需要更新其他标签，看起来更特定于在现有标签顶部创建的新框架。

Tkinter窗口打开，没有标签
