I'm unsure again with something what I'm sure is going to be very simple...

Basically, I'm trying to make my first script call/execute a bunch of other scripts but the problem is I want each individual script to contain its own functions not be called from the first secript...

First script/main script:

from datetime import date, timedelta
from sched import scheduler
from time import time, sleep, strftime
import random

s = scheduler(time, sleep)
random.seed()

def periodically(runtime, intsmall, intlarge, function):
     ## Get current time
    currenttime = strftime('%H:%M:%S')

    ## If currenttime is anywhere between 23:40 and 23:50 then...
    if currenttime > '23:40:00' and currenttime < '23:50:00':
        ## Call clear
        clear()
        ## Update time
        currenttime = strftime('%H:%M:%S')

    ## Idle time
    while currenttime > '23:40:00' and currenttime < '23:59:59' or currenttime >= '00:00:00' and currenttime < '01:30:00':
        ## Update time
        currenttime = strftime('%H:%M:%S')

    runtime += random.randrange(intsmall, intlarge)
    s.enter(runtime, 1, function, ())
    s.run()

def callscripts():
    print "Calling Functions"

    errors = open('ERROR(S).txt', 'a')
    try: 
        execfile("data/secondary.py")
    except Exception as e:
        errors.write(str(e))
        errors.write("""
""")         
    errors.close()


while True:
    periodically(2, -1, +1, callscripts)

Below is secondary.py

import win32con
from win32api import *
from win32gui import *

class WindowsBalloonTip:
    def __init__(self, title, msg):
        message_map = { win32con.WM_DESTROY: self.OnDestroy,}

        # Register the window class.
        wc = WNDCLASS()
        hinst = wc.hInstance = GetModuleHandle(None)
        wc.lpszClassName = 'PythonTaskbar'
        wc.lpfnWndProc = message_map # could also specify a wndproc.
        classAtom = RegisterClass(wc)

        # Create the window.
        style = win32con.WS_OVERLAPPED | win32con.WS_SYSMENU
        self.hwnd = CreateWindow(classAtom, "Taskbar", style, 0, 0, win32con.CW_USEDEFAULT, win32con.CW_USEDEFAULT, 0, 0, hinst, None)
        UpdateWindow(self.hwnd)

        # Icons managment
        iconPathName = "icon1.ico" ## LOCATION TO THE ICON FILE
        icon_flags = win32con.LR_LOADFROMFILE | win32con.LR_DEFAULTSIZE
        try:
            hicon = LoadImage(hinst, iconPathName, win32con.IMAGE_ICON, 0, 0, icon_flags)
        except:
            hicon = LoadIcon(0, win32con.IDI_APPLICATION)
        flags = NIF_ICON | NIF_MESSAGE | NIF_TIP
        nid = (self.hwnd, 0, flags, win32con.WM_USER+20, hicon, 'Tooltip')

        # Notify
        Shell_NotifyIcon(NIM_ADD, nid)
        Shell_NotifyIcon(NIM_MODIFY, (self.hwnd, 0, NIF_INFO, win32con.WM_USER+20, hicon, 'Balloon Tooltip', msg, 200, title))
        # self.show_balloon(title, msg)
        sleep(5)

        # Destroy
        DestroyWindow(self.hwnd)
        classAtom = UnregisterClass(classAtom, hinst)
    def OnDestroy(self, hwnd, msg, wparam, lparam):
        nid = (self.hwnd, 0)
        Shell_NotifyIcon(NIM_DELETE, nid)
        PostQuitMessage(0) # Terminate the app.

# Function
def balloon_tip(title, msg):
    w=WindowsBalloonTip(title, msg)


balloon_tip("test test", "Running")

def hi():
    print "hi"

hi()

Error:

global name 'WindowsBalloonTip' is not defined

Full Error:

Traceback (most recent call last):
  File "C:\Main.py", line 48, in <module>
    periodically(2, -1, +1, callscripts)
  File "C:\Main.py", line 27, in periodically
    s.run()
  File "C:\Python27\lib\sched.py", line 117, in run
    action(*argument)
  File "Main.py", line 34, in callscripts
    execfile("data/secondary.py")
  File "data/secondary.py", line 93, in <module>
    balloon_tip("test test", "Running")
  File "data/secondary.py", line 78, in balloon_tip
    w=WindowsBalloonTip(title, msg)
NameError: global name 'WindowsBalloonTip' is not defined

How would I go about fixing this?

Thanks in advance Hyflex

首先，

class WindowsBalloonTip:

应该

class WindowsBalloonTip(object):

因为前者是一个老式的类，它在 Python 3 中消失了，在 Python 2.x 的最新版本中只是为了向后兼容。

Ethan 的回答是正确的，但如果您问这个问题，您可能不清楚。完整的解释在这里。

运行时ballon_tip()，它首先在本地命名空间——balloon_tip()的命名空间——中搜索名为WindowsBalloonTip. 当它找不到它时，它会搜索全局命名空间。由于您没有为 toglobals参数提供任何内容execfile()，因此它默认为 的名称空间callscripts()，其中没有任何名称WindowsBaloonTip，并且错误。

要解决此问题，您可以将globals()其作为参数传递给execfile，但这会污染您的主脚本的全局命名空间，这可能是您不想要的。您还可以将 secondary.py 中的所有内容声明为全局，但您可能不想这样做，因为重点是测试 secondary.py。

问题是execfile。execfile是一种丑陋的、骇人听闻的做事方式。import更好。一种解决方案是在 secondary.py 中编写类似这样的内容：

def test_harness():
    balloon_tip("test test", "Running")
    hi()

然后，import secondary, traceback在你的主脚本中，像这样改变 callscripts() ：

def callscripts():
        print "Calling Functions"
        errors = open("ERRORS(S).txt", "a")

        try:
            secondary.test_harness()
        except:
            errors.write(traceback.format_exc() + '\n')

编辑以回应评论：在脚本的顶部import traceback，然后：

def callscripts():
        print "Calling Functions"
        errors = open("ERRORS(S).txt", "a")

        try:
            execfile("data/secondary.py", {})
        except:
            errors.write(traceback.format_exc() + '\n')

问题是执行文件。

基本上，execfile是看中exec了一个文件。因此，当您调用Python 时，会在调用execfile 的上下文中execfile 'secondary.py'执行所有行。 在这种情况下，它位于函数内部。secondary.py callscripts

您可能想要的是subprocess。
