有段程序报a bytes-like object is required, not 'str'

Davelu 2019-12-31 10:10:44
源程序为




def advanced_info_of_resource(resource, needed_attributes, storwize_connection, *id_of_resource):



	""" needed_attributes - list of parameters, that we wont to get

	    id_of_resource - list of additional parameters, that uniquely determine resource.

	    Example: for PSU - first element of list is enclosure_id, secondary element of list is PSU_id"""





	if resource == 'lsenclosure':

		stdin, stdout, stderr = storwize_connection.exec_command('svcinfo {0} {1}'.format(resource, id_of_resource[0]))

	elif resource == 'lsenclosurepsu':

		stdin, stdout, stderr = storwize_connection.exec_command('svcinfo {0} -psu {1} {2}'.format(resource, id_of_resource[1], id_of_resource[0]))



	if len(stderr.read()) > 0:

		storwize_logger.info("Error Occurs in advanced info of enclosure - {0}".format(stderr.read()))

		storwize_logout(storwize_connection)

		sys.exit("1100")

	else:

		attributes_of_resource = stdout.read() #  (variable contain advanced attributes in string)

		dict_of_attributes = {} # (will contain advanced attributes in key-value)

		try:

			for attribute in attributes_of_resource.split('\n'): 

				if len(attribute) > 0:

					temp = attribute.split(' ')

					dict_of_attributes[temp[0]] = temp[1]

		except Exception as oops:

			storwize_logger.error("Error occures in function advanced_info_of_resource - {0}".format(oops))

			storwize_logout(storwize_connection)

			sys.exit("1100")



	#  (create dictionary that contain properies of resource)

	result = {}

	for each_value in needed_attributes:

		result[each_value] = dict_of_attributes[each_value]



	return result


报错信息为：ERROR - Error occures in function advanced_info_of_resource - a bytes-like object is required, not 'str'，我应该怎么调整？

解决python3读取Python2存储的pickle文件问题
我在使用python3.5处理一个序列化文件xxx.pk，不过这个.pk文件是我在python2.7里面存储的，当我用python3读取的时候就会报如下的错误。 import pickle picklefile=open('2ohsumed_wmd_d.pk','rb') data=pickle.load(picklefile) print (data) UnicodeDecodeError: 'ascii' codec can't decode byte 0xa0 in position 11: ordinal not in range(128) 解决办法： import pickle
用python3读取python2的pickle数据方式
问题一：TypeError: a bytes-like object is required, not ‘str’ 解决：该问题属于Python3和Python2的字符串兼容问题，数据文件是在Python2下序列化的，使用Python3读取时，需要将‘str’转化为’bytes’。 picklefile=open('XXX.pkl','r') class StrToBytes: def __init__(self, fileobj): self.fileobj = fileobj def read(self, size): return self.fileobj.re
解决csv.writer写入文件有多余的空行问题
在用csv.writer写入文件的时候发现中间有多余的空行。 最早打开方式只是‘w’，会出现多余的空行，网上建议使用binary形式‘wb’打开可以解决问题： with open('egg2.csv', 'wb') as cf: 不过只能在python2下运行，python3报错： TypeError: a bytes-like object is required, not 'str' 有人建议用encode(‘utf-8′)编码转变格式，但是觉得还是比较繁琐，因为list也不支持直接的编码。 再找了一圈，找到的最佳解释： python2.x中写入CSV时，CSV文件的创建必须加上’b’

解决 Python3 中 TypeError: a bytes-like object is required, not ‘str‘
1.在运行程序时报错： TypeError: a bytes-like object is required, not ‘str’ 2.解决方案 3.原因 问题时 Python2 字符串有 str 和 unicode 两种类型；而 Python3 字符串仅有 str 类型。而Python2 和 Python3 的 str 类型是不同的；Python2中，str 类型和 bytes 类型是同一种类型。以下语句在python2中等效： a = 'ab' a = b'ab' Python3中，str 类型和
