Question

我有一个应更改的变量，名为“ scrolldown”。它不会从0更改，但我不知道为什么。这是我的代码。任何帮助表示赞赏。出于某种原因，无论何时python打印变量“ scrolldown”，它始终为0，无论它应该经过0 + 1多少次。我都尝试将变量从int（scrolldown）更改为向下滚动并从+1到+ 1但都不行。该变量在开始时定义为“ 0”，但我不明白为什么这会引起问题。为什么在脚本运行时不更改此变量？

scrolldownunits = int(903 - 553)
scrolldown = 0
Test2 = True

def movelisting():
        print(scrolldown)
        for i in range(scrolldown):
                scrolldowncalc = scrolldown * int(scrolldownunits) * -1
                pyautogui.scroll(scrolldowncalc)
        pyautogui.click()
        time.sleep(5)
        movelisting1 = 1
        Test2 = False
        listingcheck()


def listingcheck():
    if Test2 == True:
        movelisting1 = 0
        scrolldown = 0
    if movelisting1 != 1:
        pyautogui.moveTo(914, 499)   ##CLICK ON EBAY LISTING
        pyautogui.click()
        time.sleep(5)
    if pyautogui.locateOnScreen('NoClothing.png') != None: ###something not working here
        i = True
        o = pyautogui.locateOnScreen('BackArrow.png')
        print(o)
        p = pyautogui.center(o)
        pyautogui.click(p)
        time.sleep(5)
        pyautogui.moveTo(914, 499)
        time.sleep(2)
        scrolldown = scrolldown +1
        movelisting()
    elif pyautogui.locateOnScreen('NoBikes.png') != None: ###SEARCHES FOR THINGS WE DONT WANT
        h = True
        c = pyautogui.locateOnScreen('BackArrow.png')
        d = pyautogui.center(c)
        pyautogui.click(d)
        time.sleep(5)
        pyautogui.moveTo(914, 499)
        time.sleep(2)
        scrolldown = scrolldown +1
        movelisting()
    elif pyautogui.locateOnScreen('NoSelections.png') != None:
        g = True
        e = pyautogui.locateOnScreen('BackArrow.png')
        f = pyautogui.center(e)
        pyautogui.click(f)
        time.sleep(5)
        pyautogui.moveTo(914, 499)
        time.sleep(2)
        scrolldown = scrolldown +1
        movelisting()
    listingcheck1 = True  ##USED FOR VAR DELETE
    listingcapture() ###CONTINUES ONTO NEXT STEP

在函数内部分配全局变量时，首先需要让Python知道您打算修改全局变量。默认情况下，当您进行分配时，Python将在函数范围内创建一个具有相同名称的新变量。将“全局向下滚动”添加到listingcheck（）的顶部。

Python变量没有改变
