如下所示： #!/usr/bin/python import pickle shoplist=['apple','mango','carrot'] f = open('c:\poem.txt','w') pickle.dump(shoplist,f) f.close() del shoplist f = open('c:\poem.txt','r') storedlist = pickle.load(f) print(storedlist) 执行上述程序时候报错： TypeError: must be str, not bytes 解决方法：在使用open打开文件的时候，加个b f

This error typically occurs when the code is expecting a bytes-like object (e.g. bytes, bytearray, memoryview) but instead receives a string object. To resolve this error, you can convert the string to bytes using the `encode()` method. For example: ``` my_string = "Hello, world!" my_bytes = my_string.encode() ``` Alternatively, you can ensure that the code is expecting a string object by modifying the relevant functions or methods.
