【问题描述】:
我正在尝试使用 xlsxwriter 创建一个 excel 工作簿,但是当我尝试执行 workbook.close() 时出现以下异常:
Traceback (most recent call last):
File "/usr/local/bin/fab", line 11, in <module>
sys.exit(program.run())

AttributeError: 'tuple' object has no attribute 'tell'
Exception AttributeError: "'tuple' object has no attribute 'tell'" in <bound method ZipFile.__del__ of <zipfile.ZipFile object at 0x7f87fcffa410>> ignored
我正在查询一个数据库,然后创建 3 张工作表并在其中填写表格,代码如下:
def summary_main():
start_time = time.time()
print "starting job}"
##setup db and extract summaries
files_last_date = input("date in yyyy-mm-dd")
sql_h = SqlHelper()
date = datetime.today().strftime("%Y-%m-%d")
file_name=('/app/SUMMARY_',date,'.xlsx')
print "file name created = ",file_name
workbook = xlsxwriter.Workbook(file_name)
get_uploaded_files(workbook,files_last_date,sql_h)
# getting exception in the following line
workbook.close()
print "\n\nSummary has been saved, workbook closed"
上面的代码在我的本地机器上的 python3 中运行良好,但是在服务器上我们试图在 python2 上运行相同的代码,这是代码不起作用的原因吗?在最后一行抛出异常,这意味着在此之前没有兼容性问题。在 get_uploaded_files 函数中,我查询数据库并将数据写入工作表,如下所示:
def get_uploaded_files(wb,dt,sql_h):
sheet = wb.add_worksheet("Uploaded Files")
data_set = sql_h.getData(dt,1)
header = ["File ID", "First Name", "Last Name", "File Name", "Comments"]
sql_h.parse_sql_data(sheet,header,data_set,wb)
以下 2 个函数在名为 SqlHelper_py2.py 的单独文件中定义
def getData(self,dt,case):
print(self.conn)
cur=self.conn.cursor()
data_set=""
if case==1:
cur.execute(self.sql_uploaded_file.replace("%s",str(dt)))
data_set=cur.fetchall()
cur.close()
return data_set
def parse_sql_data(self,sheet,header,data_set,workbook):
format_bold=workbook.add_format({'bold': True,'border':1})
format_border=workbook.add_format({'border':1})
col = 0
count=0
dict_max={0:0}
for h in header:
sheet.write(0,col,h,format_bold)
col+=1
dict_max[count]=len(str(h))
count+=1
row = 1
for data in data_set:
col=0
for d in data:
if(dict_max[col] is not None and len(str(d))>dict_max[col]):
dict_max[col]=len(str(d))
if("datetime.datetime" not in str(type(d))):
sheet.write(row,col,d,format_border)
col+=1
row+=1
for key in dict_max:
sheet.set_column(key,key,dict_max[key]+5)
【问题讨论】:
-
确保
xlsxwriter版本相同。如果两者都需要支持 Python 2 和 3,这可能是一个挑战 -
@DeepSpace 我创建了以下演示代码来测试它是否有效:
def test3():workbook = xlsxwriter.Workbook('/app/cdpgrp/gp_brms/hello.xlsx')worksheet = workbook.add_worksheet()worksheet.write('A1', 'Hello..')worksheet.write('A1', 'Hello..')worksheet.write('B1', 'Geeks')workbook.close()并且此代码工作正常,能够创建excel表格,所以我不认为xlsxwriter的版本有问题。 -
请注意,异常发生在 zipfile 而不是 xlsxwriter 中。是因为某些权限问题吗?简单的 hello_world.py 案例在两个平台上都可以正常工作吗?
-
@jmcnamara 两个代码都在同一个环境中运行,如果有一些权限错误,那么 helloworld 也不会工作,对吧?我是python新手,所以我主要是在猜测,我来自java背景
-
@gpd 如果 hello world 示例在两种环境中都有效,那么这不是权限问题。我认为您需要通过删除功能来调试它,直到您有一个工作示例(最小目标中的 hello world)。我是 XlsxWriter 的作者/维护者,我从未见过这样的问题,也没有任何 Python 2/3 兼容性问题。
