阅读CSV文件并在python中的每个项目上加上双引号

Question

我是python的新手,我有一个简单的问题.我有一个包含以下内容的.csv文件:

123,456,789

我想读它并将其存储到一个名为"number"的变量中,格式如下

"123","456","789"

所以,当我这样做

print number

它将提供以下输出

"123","456","789"

有人可以帮忙吗？

谢谢!

更新:以下是我的代码:

input = csv.reader(open('inputfile.csv', 'r'))
for item in input:
    item = ['"' + item + '"' for item in item]
print item

它给出了以下输出:

['"123"', '"456"', '"789"']

Answer 1

这是怎么做的:

import csv
from io import StringIO

quotedData = StringIO()

with open('file.csv') as f:
    reader = csv.reader(f)
    writer = csv.writer(quotedData, quoting=csv.QUOTE_ALL)
    for row in reader:
       writer.writerow(row)

与reader=csv.reader(StringIO('1,2,3'))输出为:

print quotedData.getvalue()
"1","2","3"
