我正在尝试将列表列表写入新文件,但出现此错误:
回溯(最后一次调用):文件“”,第 1 行,在 dowork() 文件“C:\Python27\work\accounting\formatting quickbooks file\sdf.py”,第 11 行,在 dowork WriteFile() 文件“C :\Python27\work\accounting\formatting quickbooks file\sdf.py", line 71, in WriteFile f.write(thefile) TypeError: expected a character buffer object
如何将列表的列表写入文件?
这就是我的写作方式:
def WriteFile():
global thefile
f = open("output"+'.csv','w')
f.seek(0)
f.write(thefile)
f.close()
如果您需要,这里是完整的源代码:
import csv
thefile = []
output = []
def dowork():
sourceFile='e.csv'
thefile=ReadFile(sourceFile)
CleanFile(sourceFile)
ProcessFile()
WriteFile()
def ReadFile(filename):
return list(csv.reader(open(filename, 'rb'), delimiter=',', quotechar='"'))[1:]
def CleanFile(sourceFile):
global thefile
thefiletmp=[]
for i, line in enumerate(thefile):
if line[2]=='':
del thefile[i]
else:
thefiletmp.append(line[4:])
thefile=thefiletmp
def ProcessFile():
global thefile
iCompany=1
iNum=0
iDate=2
iAging=3
iBalance=4
COMPANIES=GetDistinctValues(1)
mytemparray=[]
mytempfile=[]
for company in COMPANIES:
for line in thefile:
if line[iCompany]==company:
mytemparray.append(line[iCompany])
mytemparray.append(line[iNum])
mytemparray.append(line[iDate])
if line[2] in range(0,31):
mytemparray.append(line[iBalance])
mytemparray.append('0')
mytemparray.append('0')
mytemparray.append('0')
if line[2] in range(31,61):
mytemparray.append('0')
mytemparray.append(line[iBalance])
mytemparray.append('0')
mytemparray.append('0')
if line[2] in range(61,91):
mytemparray.append('0')
mytemparray.append('0')
mytemparray.append(line[iBalance])
mytemparray.append('0')
if line[2] >90:
mytemparray.append('0')
mytemparray.append('0')
mytemparray.append('0')
mytemparray.append(line[iBalance])
mytempfile.append(mytemparray)
mytemparray=[]
thefile=mytempfile
def WriteFile():
global thefile
f = open("output"+'.csv','w')
f.seek(0)
f.write(thefile)
f.close()
def GetDistinctValues(theColumn):
return sorted(list(set(line[theColumn] for line in thefile)))
