我能够输出我输出的MYSQL命令,为了安全起见,我已经删除了,但是当我尝试将此制表符分隔的输出写入CSV时,我一直收到错误。任何有助于提升Python新秀的帮助都将受到赞赏。

with open("/home/oatey/" + du + ".txt", 'rb') as data:
cr = data.readlines()
contents = [line for line in cr]
with open("/home/oatey/" + du + ".csv", "wb") as wd:
cw = csv.writer(wd, quotechar='', quoting=csv.QUOTE_NONE)
wd.write(contents)
答案 0 :(得分:1)
我打赌你得到的错误是:
TypeError:必须是字符串或缓冲区,而不是列表
contents
是一个列表,您无法通过write()
撰写列表。引自docs:
file.write(str)
将字符串写入文件。
相反,请使用csvwriter.writerows():
with open("/home/oatey/" + du + ".csv", "wb") as wd:
cw = csv.writer(wd, quotechar='', quoting=csv.QUOTE_NONE)
cw.writerows(contents)
