[Tutor] No module named player_data

[Michael bridges]

why does this happen?

server [folder]
   player_data [folder]
   server.py

Traceback (most recent call last):
  File 
"C:\Users\MySelf\Program\game_stuff\Game_28_02_11\Servers\server_client_begining\server.py",
 line 3, in 
from player_data import PlayerArmy
ImportError: No module named player_data


from player_data import PlayerArmy
from player_data import PlayerBaseData
from player_data import PlayerEnabledFlags
from player_data import PlayerResearch
from player_data import PlayerResearchers
from player_data import PlayerTotalWeapons
from player_data import PlayerWeaponsEquipped
from player_data import PlayerWeaponsUnequipped

this worked before i tried:
from player_data import *
"""from player_data import PlayerArmy
from player_data import PlayerBaseData
from player_data import PlayerEnabledFlags
from player_data import PlayerResearch
from player_data import PlayerResearchers
from player_data import PlayerTotalWeapons
from player_data import PlayerWeaponsEquipped
from player_data import PlayerWeaponsUnequipped"""

got error about PlayerBaseData not found

then undid back to:
from player_data import PlayerArmy
from player_data import PlayerBaseData
from player_data import PlayerEnabledFlags
from player_data import PlayerResearch
from player_data import PlayerResearchers
from player_data import PlayerTotalWeapons
from player_data import PlayerWeaponsEquipped
from player_data import PlayerWeaponsUnequipped

more specific general info [do not want to copy/paste the whole files]:

[\server_client_begining\server.py]
from player_data import PlayerArmy


[\server_client_begining\player_data\PlayerArmy]
#PlayerArmy
playerName = "john"
militia_amount = 100
military_amount = 10
[with more variables]
[no classes, no functions, just variables]

[Tutor] floats

[Michael bridges]

i saw it somewhere, but where?

i want to 10 / 1000 and get 0.01 not 0
if 1000 is made 1000.00 then 0.01 is printed
but that gives 500 / 1000.00 is 0.5 not 0.50

i might be thinking C# not python.

can someone till me how to get a two decimal precision every time?
