NameError：未定义名称“字符”

我正在尝试做的是：

我正在对pickle包含字符统计信息的字典使用函数。我定义了一个字典，定义了字符统计信息，如下所示：

character = {'health': health, 'damage': damage, 'shield': shield, 'magic': magic, 'luck': luck, 'name': name}

然后，我要求用户输入以告知程序用户想要调用其保存文件的内容，然后使用我的save_character函数进行保存。

用户输入：

character_file_name = input('> ')
save_character(character_file_name)

保存字符功能如下所示：

def save_character(save_name):
    save_name_pickle = save_name + '.pickle'
    type('> saving character')
    w(1)
    with open(save_name_pickle, 'wb') as f:
        pickle.dump(character, f)
        type('> character saved successfully')

问题：

如果我运行该程序，并要求输入文件名，则会返回名称错误：

NameError: name 'character' is not defined

即使我可以看到已经定义了这个。

完全回溯错误：
