你好我有 python 學(xué)習(xí)項目。我想在 GUI 中插入兩個數(shù)字，它們定義程序從中生成隨機數(shù)的范圍。我確實在按下按鈕調(diào)用函數(shù)時遇到問題。并不斷出現(xiàn)錯誤 ValueError: invalid literal for int() with base 10: ''，當(dāng)嘗試將字符串從 GUI 中的條目轉(zhuǎn)換為 int，然后將它們插入 random.randint 時。感謝幫助！from tkinter import *import randomroot = Tk()root.title("Generator custom random number")#function that gets number from entry converts string to int and defines target number in stevilodef function():    string_answer1 = prvo_stevilo.get()    int1 = int(string_answer1)    string_answer2 = drugo_stevilo.get()    int2 = int(string_answer2)    stevilo = random.randint(int1, int2)#Defining GUInavodilo = Label(root, text="Choose custom lower and upper number to chose random number from", width=60)navodilo2 = Label(root, text="From", width=20, borderwidth=3)navodilo3 = Label(root, text="To", width=20, borderwidth=3)prvo_stevilo = Entry(root, width=20, borderwidth=3)drugo_stevilo = Entry(root, width=20, borderwidth=3)gumb = Button(root, text="Generate number", width=17, height=2, command=function)praznavrstica = Label(root, text="")izpis = Label(root, text="Random number is: ", width=20)izpis_stevila = Label(root, text="" + stevilo)#Showcase of guinavodilo.grid(row=0, column=0, columnspan=1)navodilo2.grid(row=1, column=0, columnspan=1)navodilo3.grid(row=3, column=0, columnspan=1)prvo_stevilo.grid(row=2, column=0, columnspan=1)drugo_stevilo.grid(row=4, column=0, columnspan=1)praznavrstica.grid(row=5, column=0, columnspan=1)gumb.grid(row=6, column=0, columnspan=1)praznavrstica.grid(row=7, column=0, columnspan=1)izpis.grid(row=8, column=0, columnspan=1)izpis_stevila.grid(row=9, column=0, columnspan=1)#Looproot.mainloop()
