如何修改和删除Python2字典键中的特殊字符

# 原始字典
original_dict = {"key1": "value1", "key2#": "value2", "key3$": "value3"}

# 创建一个新的字典
new_dict = {}

# 遍历原始字典的键
for key in original_dict.keys():
    # 检查键的类型是否为字符串
    if isinstance(key, str):
        # 替换特殊字符
        new_key = key.replace("#", "").replace("$", "")
        # 将新的键值对添加到新的字典中
        new_dict[new_key] = original_dict[key]

# 将新的字典赋值给原始字典
original_dict = new_dict

# 打印修改后的字典
print(original_dict)
