你似乎并不太會(huì)使用global關(guān)鍵字。global 關(guān)鍵字告訴程序這個(gè)變量不在塊作用域，也不在函數(shù)作用域， 你要找直接到全局作用域中找。什么時(shí)候用? 局部作用域中有變量名和全局域的變量名相同，而這種情況下，你又需要使用全局的那個(gè)變量，那么你需要在使用這個(gè)變量之前用global聲明一下。

因此在你的這個(gè)例子中，即便要使用global也應(yīng)該在add_task中使用。其次，在這里根本就沒(méi)有必要使用global關(guān)鍵字，只需要將你用global聲明的變量放到全局域中(不是if name == "__main__")的條件塊中。最后@Leo黎詩(shī)霆 說(shuō)的也是正確的，程序被阻塞了，你后面的代碼壓根不會(huì)執(zhí)行。當(dāng)然，通過(guò)把這些代碼放到app.run之前是沒(méi)有用的。

試一下把app.run(host = '0.0.0.0')放到最后一句。因?yàn)槌绦蜻\(yùn)行到這里會(huì)阻塞，后面的聲明和初始化都沒(méi)有執(zhí)行。

用以上代碼可以實(shí)現(xiàn)，另樓上的建議非常好
