All right, now that we have our lovely table
0:02
with Mike, Bob, and myself in it,
0:04
and our very realistic addresses,
0:08
let's actually print some of that data out.
0:11
So we're going to do that within the Python shell.
0:13
Again, import sqlite3, getting tedious by now.
0:18
So, we will run our connection,
0:21
con equals sqlite3.connect.
0:28
addressbook.db.
0:31
'Kay, c = con.cursor to get our cursor.
0:37
Now to print the actual data within the database,
0:40
we need to put this into a for loop, okay?
0:44
Just bear with me, because we're going to
0:45
iterate over these three rows, okay?
0:50
So, the way we do that, is we go for row in c.execute.
0:57
We're going to select data.
1:00
Now what data were we going to select?
1:02
We're going to select everything from our details table,
1:07
all right, so for row in c.execute.
1:09
Select all from details.
1:12
What next?
1:14
Well, once it's got the row,
1:17
we want to print the row.
1:19
And that's it.
1:22
And there are our three lines.
1:24
You've got these, the formatting's a bit off,
1:26
it's actually taking that data,
1:30
or the literal, the tuple for that, for that row, you know?
1:33
So it doesn't look that great.
1:36
So to actually make that look a little bit better,
1:39
let's just bring that back up to save me some time.
1:42
We can actually choose which column to view,
1:46
so we can go print row...
1:50
Zero.
1:54
Julian, Bob, Mike.
1:56
And once we have this sort of information,
1:59
you can start to pop a few strings together,
2:03
you know, start making sentences from these,
2:05
these sorts of database pulls.
2:08
So let's do one really quickly here.
2:13
And there we go.
2:14
So Julian lives at 123 Fake Street, blah blah blah,
2:16
and his phone number X, okay?
2:19
And that's the sort of manipulation we can do
2:21
by pulling the data out of the database.
