<p>我将python列表转换为Pandas数据帧，然后将数据帧写入csv。清单如下：</p>
<pre><code>name = ['james beard', 'james beard']
ids = [304589, 304589]
year = [1999, 1999]
co_authors = [['athman bouguettaya', 'boualem benatallah', 'lily hendra', 'kevin smith', 'mourad quzzani'], ['athman bouguettaya', 'boualem benatallah', 'lily hendra', 'kevin smith', 'mourad quzzani']]
title = ['world wide databaseintegrating the web corba and databases', 'world wide databaseintegrating the web corba and databases']
venue = ['international conference on management of data', 'international conference on management of data']
data = {
'Name': name,
'ID': ids,
'Year': year,
'Co-author': co_authors,
'Title:': title,
'Venue:': venue,
}
df = pd.DataFrame(data, columns=['Name','ID','Year','Co-author','Title', 'Venue'])
df
df.to_csv('test.csv')
</code></pre>
