Python基础 —— 使用 pickle 模块存储数据报错的解决办法

# 写入错误TypeError: write() argument must be str, not bytes# 读取错误UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 0: illegal multibyte sequence

解决方案：

def storeTree(inputTree, fielname):    import pickle    # 写文件时，注明 'wb'    fw = open(fielname, 'wb')    pickle.dump(inputTree, fw)    fw.close()def grabTree(filename):    import pickle     # 读文件时，注明 'rb'    fr = open(filename, 'rb')    fr = open(filename)    return pickle.load(fr)storeTree(myTree, 'classifierStorage.txt')print(grabTree('classifierStorage.txt'))

输出：

{'no surfacing': {0: 'no', 1: {'flippers': {0: 'no', 1: 'yes'}}}}Process finished with exit code 0
