请问! 为什么这段代码在我这报错啊?
from tkinter import *root = Tk()
Label(root,text="账号:").grid(row=0,column=0)
Label(root,text="密码:").grid(row=1,column=0)
v1 = StringVar()
v2 = StringVar()
e1 = Entry(root,textvariable=v1)
e2 = Entry(root,textvariable=v2,show="*")
e1.grid(row=0,column=1,padx=10,pady=5)
e2.grid(row=1,column=1,padx=10,pady=5)
def show():
print (u"账号:%s")% e1.get()
print (u"密码:%s")% e2.get()
Button(root,text="芝麻开门",width=10,command=show)\
.grid(row=3,column=0,sticky=W,padx=10,pady=5)
Button(root,text="退出",width=10,command=root.quit)\
.grid(row=3,column=1,sticky=E,padx=10,pady=5)
mainloop()
报错信息如下:
Exception in Tkinter callback
Traceback (most recent call last):
File "E:\Python34\lib\tkinter\__init__.py", line 1487, in __call__
return self.func(*args)
File "E:/Python34/7.py", line 17, in show
print (u"账号:%s")% e1.get()
TypeError: unsupported operand type(s) for %: 'NoneType' and 'str' 本帖最后由 isdkz 于 2022-2-17 14:36 编辑
改一下16到18行,那是python2的写法
def show():
print("账号:%s" % e1.get())
print("密码:%s" % e2.get()) 16/17/18行的代码错了,太老了 修改一下17.18行的代码
