python - return didn't return. Windows api

Question

Here's my code. When I run it the return statement doesn't return anything. Anyone know why?

import win32api as win
import time
import sys
def mouse_path(run):
    path = []
    while time.clock() < run:
        cords = (win.GetCursorPos())
        time.sleep(.1)
        path.append(cords)
    return path

mouse_path(10)

看起来您是从 .py 文件而不是在交互模式下运行它。除非在交互模式下，否则不会显示从return语句返回的对象。尝试将返回的值包装在print语句中。

import win32api as win
import time
import sys
def mouse_path(run):
    path = []
    while time.clock() < run:
        cords = (win.GetCursorPos())
        time.sleep(.1)
        path.append(cords)
    return path

print(mouse_path(10))

我运行它并将其打印到屏幕上：
