我真的是 Python 新手,在网上找到了我修改过的这个片段,现在我让它打印 x * y 但我希望能够将它作为一个 int 值返回,以便我以后可以再次使用它脚本.
I am really new to Python and found this snippet online that I've modified, right now I have it printing x * y but I want to be able to return it as a int value so I can use it again later in the script.
我使用的是 Python 2.7.6.
I'm using Python 2.7.6.
def show_xy(event):
xm, ym = event.x, event.y
x3 = xm * ym
print x3
root = tk.Tk()
frame = tk.Frame(root, bg = 'yellow',
width = 300, height = 200)
frame.bind("<Motion>", showxy)
frame.pack()
root.mainloop()
亲切的问候,邮差
要返回一个值,你只需使用 return
而不是 print
:
To return a value, you simply use return
instead of print
:
def showxy(event):
xm, ym = event.x, event.y
x3 = xm*ym
return x3
def print_val(a):
print a
>>> print_val(5)
5
def return_val(a):
return a
>>> result = return_val(8)
>>> print result
8
