用CSV编写字符串并获取多行-Python

Question

This must be very simple.

I'm trying to put a header in my csv file, the string 'Date,Value', as you can see below.

with open('ticker.csv', 'wb') as f:

writer = csv.writer(f)
writer.writerows('Date,Value')
writer.writerows(izip(dates, values))
f.close()

However I'm getting a multirowed string, like this:

D

a

t

e

","

V

a

l

u

e

2002-04,12.5

2002-05,11.9

How can I fix that?

Answer 1

使用writerow （不带s）来写一行。

Answer 2

Here is the solution

writer = csv.writer(f)
writer.writerow(['Date','Value'])
writer.writerows(izip(dates, values))
f.close()
