#63927 — Printer list value problem

Hello,
I confudsed,need printer the value of list (this is reaer from csv) . The reader is ok, but my problem is in the print moment because printer only the last value. For example my csv is:

[........]
user1@example.com;user1;lastName;Name
user2@example.com;user2;lastName;Name
[........]

But when execute the script I view the print is only the last user

[........]
ca user2@example.com displayName 'user2' sn 'lastName' cn 'Name'
[........]

And I need the next printer

[........]
ca user1@example.com displayName 'User1' sn ''lastName" cn 'Name'
ca user1@example.com displayName 'User2' sn ''lastName" cn 'Name'
[........]

My script is 

[........]
#!/usr/bin/python
import csv
with open ('users.csv', 'rb') as f:

        reader = csv.reader (f, delimiter=';' ) #delimiter tabulador
        for row in reader:

                mail     = row [0]
                name     = row [3]
                lastname = row [2]

        print "ma {} displayName '{}' sn '{}'".format(mail,name,lastname)

f.close()
[........]


Thanks.

This line is indented the same amount as the 'for' loop, which means
that it will be executed after the loop has finished.

You don't need to close the file here because the 'with' statement will
do that for you.

Your print statement needs to be inside the for loop, you currently have 
it after the loop has finished.

Would you also please read and action this 
https://wiki.python.org/moin/GoogleGroupsPython to prevent us seeing the 
double line spacing above, thanks.

This print needs to be at the same indentation as the previous bit.


> f.close()

This .close() is superfluous--the "with" takes care of that for you.

I'd also unpack the row as I iterate to make it easier to read.  That
would make the final look something like

  with open("users.csv", "rb") as f:
    reader = csv.reader(f, delimiter=';')
    for mail, _, lastname, name in reader:
      print "ca {} displayName '{}' sn '{}'".format(
        mail, name, lastname)
