我正在使用Tkinter制作测试程序,但我遇到了一些麻烦。
我正在尝试制作用户总是丢失的Rock,Paper,Scissors游戏,但我得到“Label没有调用实例”,这里是代码:
#Rock papers & scissor
import Tkinter as tk
class App(tk.Tk):
def setLabel(self):
entry2 = self.entry.get()
if entry2 == "paper":
self.l1(App, text="Scissors, you loose!")
elif entry2 == "Paper":
self.l1(text="Scissors, you loose!")
elif entry2 == "PAPER":
self.l1(text="Scissors, you loose!")
elif entry2 == "rock":
self.l1(text="Paper, you loose!")
elif entry2 == "Rock":
self.l1(text="Paper, you loose!")
elif entry2 == "ROCK":
self.l1(text="Paper, you loose!")
elif entry2 == "Scissors":
self.l1(text="Rock, you loose!")
elif entry2 == "scissors":
self.l1(text="Rock, you loose!")
elif entry2 == "SCISSORS":
self.l1(text="Rock, you loose!")
elif entry2 == "scissor":
self.l1(text="Rock, you loose!")
elif entry2 == "Scissor":
self.l1(text="Rock, you loose!")
elif entry2 == "SCISSOR":
self.l1(text="Rock, you loose!")
else:
self.l1(text="wat")
def __init__(self):
tk.Tk.__init__(self)
self.entry = tk.Entry(self)
self.btn = tk.Button(self, text="Go!", command=self.setLabel)
self.l1 = tk.Label(self, text="Waiting...")
self.entry.pack()
self.btn.pack()
self.l1.pack()
App().mainloop()
App().minsize(300, 100)
App().title("Test")
答案 0 :(得分:1)
一些问题:
self.l1(text='mytext')
不正确。当您将括号放在self.l1
之后,您试图将该标签称为函数,但它不是函数。您必须调用该标签的config()
方法。App
对象并循环它...然后您创建另一个,另一个。创建一个,保存引用,然后使用它。if
分支比实际大。mainloop()
来电应该在最后。以下修复了这些问题:
import Tkinter as tk
class App(tk.Tk):
def setLabel(self):
entry2 = self.entry.get().lower()
if entry2.startswith('p'):
self.l1.config(text="Scissors, you lose!")
elif entry2.startswith('r'):
self.l1.config(text="Paper, you lose!")
elif entry2.startswith('s'):
self.l1.config(text="Rock, you lose!")
else:
self.l1.config(text="wat")
def __init__(self):
tk.Tk.__init__(self)
self.entry = tk.Entry(self)
self.btn = tk.Button(self, text="Go!", command=self.setLabel)
self.l1 = tk.Label(self, text="Waiting...")
self.entry.pack()
self.btn.pack()
self.l1.pack()
app = App()
app.minsize(300, 100)
app.title("Test")
app.mainloop()
