python - 如何将 Python 元组转换为 .csv 文件？

Question

我想将 Python 元组转换为 .csv 文件。假设我有一个 retrive() 函数，当我用 pprint 打印它时，它看起来像这样:

test = tuple(retrive(directory))
pprint(test, width=1)

然后:

("opinion_1.txt, I am an amateur photographer and own three DSLR c.... purchase",
 "opinion_2.txt, This my second Sony Digital Came.... good camera for a good price!',
 'opinion_3.txt, \'I ordered this camera with high hopes after  couldn\\\'t find.\'')

因此，我尝试使用 csv 模块:

with open('/Users/user/Downloads/output.csv','w') as out:
    csv_out=csv.writer(out)
    csv_out.writerow(['id','content'])
    for row in test:
        csv_out.writerow(row)

问题是我得到了一个奇怪的输出，看起来像这样:

id,content
o,p,i,n,i,o,n,_,1,.,t,x,t,",", ,I, ,a,m, ,a,n, ,a,m,a,t,e,u,r, ,p,h,o,t,o,g,r,a,p,h,e,r, ,a,n,d, ,o,w,n, ,t,h,r,e,e, ,D,S,L,R, ,c,a,m,e,r,a,s, ,w,i,t,h, ,a, ,s,e,l,e,c,t,i,o,n, ,o,f, ,l,e,n,s,e,s,., ,H,o,w,e,v,e,r, ,t,h,a,t, ,c,o,l,l,e,c,t,i,o,n, 

我怎样才能得到这样的东西:

opinion_1.txt,I am an amateur photographer and own three DSLR c.... purchase
opinion_2.txt,This my second Sony Digital Came.... good camera for a good price!
opinion_3.txt,I ordered this camera with high hopes after  couldn\\\'t find.

Answer 1

CSV 尝试迭代您从元组传递的字符串。将您的代码更改为:

for row in test:
    csv_out.writerow(row.split(', ', 1))

这意味着您通过 ', ' 的第一次出现来拆分元组中的每个字符串。 它为每一行生成两个元素，这就是 csv 编写器所需要的。
