如果键值中有字符串，则删除字典

def remove_keys_with_string(dictionary, target_string):
    keys_to_remove = []
    for key, value in dictionary.items():
        if isinstance(value, str) and target_string in value:
            keys_to_remove.append(key)
    
    for key in keys_to_remove:
        del dictionary[key]
    
    return dictionary

# 示例字典
example_dict = {
    'key1': 'value1',
    'key2': 'value2_with_target',
    'key3': 'value3',
    'key4': 'another_value_with_target'
}

# 删除值包含'target'的键值对
result_dict = remove_keys_with_string(example_dict, 'target')
print(result_dict)

{'key1': 'value1', 'key3': 'value3'}
