RuntimeError: dictionary changed size during iteration 解决办法-CSDN博客

字典遍历时，不允许修改

修改前

    for key in sys.modules.keys():
        if key.startswith('selenium'):
            del sys.modules[key]

改成list

    for key in list(sys.modules.keys()):
        if key.startswith('selenium'):
            del sys.modules[key]
