You can use [random.random() * 5 for x in range(100)] but works only on range [0, 5). If you want to include 5, you will need more code.

Multiple rows from MySQL query saved in an array structure

I have this Python code:

self.lock_tables("read", ['nets_permissions as n', 'devices_permissions as d'])
usrs = self.db.get("SELECT n.user_id FROM nets_permissions as n \
                    left join devices_permissions as d \
                    on n.user_id = d.user_id \
                    where d.user_id is null \
                    and n.network_id=%s and n.perm<>3", netid)
self.unlock_tables()

for usr in usrs:
    self.lock_tables("write", ['devices_permissions'])
    self.db.execute("INSERT devices_permissions SET \
                     user_id=%s, network_id=%s, device_id=%s, perm=%s",\
                     usr, netid, sensid, perm)
    self.unlock_tables();

I first do a query to retrieve some user_id from two tables. I want save this user_id in one variable and after do a for loop to insert this records in another table...

This code doesn't work. I obtain this error:    
Exception: Multiple rows returned for Database.get() query

How can I retrieve this multiple rows and then process everyone of them at one time?

Splitting a list into even size chunks in python?

Hi,

I have a list of arbitrary length, and I need to split it up into equal size chunks. There are some obvious ways to do this, like keeping a counter and two lists, and when the second list fills up, add it to the first list and empty the second list for the next round of data, but this is potentially extremely expensive.

I was wondering if anyone had a good solution to this for lists of any length

This should work:

l = range(1, 1000)
print chunks(l, 10) -> [ [ 1..10 ], [ 11..20 ], .., [ 991..999 ] ]

I was looking for something useful in itertools but I couldn't find anything obviously useful.

Appretiate your help.
