In python what is <type 'revision'>

Question

I use pysvn to extract svn log information from subversion log history (Author, Date, Time, Revision). The code I use below:

client = pysvn.Client()
client.callback_get_login 
commit_messages = client.log("url")
log_list = []
for i, commit in enumerate(commit_messages):
    rev = commit.revision
    auth = commit.author
    t = time.ctime(commit.date)
    mess = commit.message
    log_list.append(rev)
    log_list.append(auth)
    log_list.append(t)
    log_list.append(mess)
log_file = open("extracted_log_history",'wb')
wr = csv.writer(log_file, dialect = 'excel')
for item in log_list:
    wr.writerows(item)

I found that this cannot work returning the following TypeError: writerows() argument must be iterable. I believe that this is not so, because it rev = commit.revisionreturns <type 'revision'>, and the rest of the variables (auth, t, mess) are all <type 'str'>. Any ideas on how I can get the revision number as "iterable"?

<type 'revision'>means you have an pysvn.Revisioninstance . If you want to write the version number, use the attribute revision.number.

. log_list , , CSV. csv.writerows() :

client = pysvn.Client()
client.callback_get_login
with open("extracted_log_history",'wb') as log_file:
    wr = csv.writer(log_file)
    for commit in client.log("url"):
        rev = commit.revision.number
        auth = commit.author
        t = time.ctime(commit.date)
        mess = commit.message
        row = [rev, auth, t, mess]
        wr.writerow(row)
