Bad operand type for unary +: 'str' 对于一元操作符+,操作数类型错误:'str'
Bad operand type for unary +: 'str' 对于一元操作符+,操作数类型错误:'str'
我无法解决我在Python 2.7代码中遇到的问题。我正在将引用转换为整数,但是我一直收到类型异常bad operand type for unary +: 'str'
。有人能帮忙吗?
import urllib2 import time import datetime stocksToPull = 'EBAY', 'AAPL' def pullData(stock): try: print '当前正在获取', stock print str(datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')) urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' + \ stock + '/chartdata;type=quote;range=3y/csv' saveFileLine = stock + '.txt' try: readExistingData = open(saveFileLine, 'r').read() splitExisting = readExistingData.split('\n') mostRecentLine = splitExisting[-2] lastUnix = mostRecentLine.split(',')[0] except Exception, e: print str(e) time.sleep(1) lastUnix = 0 saveFile = open(saveFileLine, 'a') sourceCode = urllib2.urlopen(urlToVisit).read() splitSource = sourceCode.split('\n') for eachLine in splitSource: if 'values' not in eachLine: splitLine = eachLine.split(',') if len(splitLine) == 6: if int(splitLine[0]) > int(lastUnix): lineToWrite = eachLine + '\n' saveFile.write(lineToWrite) saveFile.close() print '已获取', + stock print '正在睡眠....' print str(datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')) time.sleep(120) except Exception, e: print '主循环', str(e) for eachStock in stocksToPull: pullData(eachStock)
当它到达if int(splitLine[0]) > int(lastUnix):
时,我遇到了操作数异常bad operand type for unary +: 'str'
,即使在测试时,被比较的两个值都显示为整数。有人能给我一些反馈吗?谢谢!
以下是异常响应:
