你好我有 python 学习项目。我想在 GUI 中插入两个数字,它们定义程序从中生成随机数的范围。
我确实在按下按钮调用函数时遇到问题。并不断出现错误 ValueError: invalid literal for int() with base 10: '',当尝试将字符串从 GUI 中的条目转换为 int,然后将它们插入 random.randint 时。
感谢帮助!
from tkinter import *
import random
root = Tk()
root.title("Generator custom random number")
#function that gets number from entry converts string to int and defines target number in stevilo
def 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 GUI
navodilo = 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 gui
navodilo.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)
#Loop
root.mainloop()
