#🔒 Saving files
maiden holly
ive been trying to load items tht ive stored in a text file after i saved them but it doesnt seem to work? need someone to explain why its not working
Initialize game state
def initial_game_state():
return {
'day': 1,
'energy': 10,
'money': 20,
'bag': {},
'seeds': 0,
}
seed_list = ['LET', 'POT', 'CAU']
seeds = {
'LET': {'name': 'Lettuce', 'price': 2, 'growth_time': 2, 'crop_price': 3},
'POT': {'name': 'Potato', 'price': 3, 'growth_time': 3, 'crop_price': 6},
'CAU': {'name': 'Cauliflower', 'price': 5, 'growth_time': 6, 'crop_price': 14},
}
farm = [[None, None, None, None, None],
[None, None, None, None, None],
[None, None, 'House', None, None],
[None, None, None, None, None],
[None, None, None, None, None]]
#save da game
def save_game(game_vars):
with open(SAVE_FILE, 'w') as file:
file.write(f"day:{game_vars['day']}\n")
file.write(f"energy:{game_vars['energy']}\n")
file.write(f"money:{game_vars['money']}\n")
file.write("bag:" + ','.join(f"{code}:{quantity}" for code, quantity in game_vars['bag'].items()) + '\n')
file.write("farm:" + ','.join(
'None' if cell is None else ','.join(map(str, cell)) for row in farm for cell in row) + '\n')
print("Game saved!")
Load the game state from a file
def load_game():
if os.path.exists(SAVE_FILE):
state = initial_game_state() # Start with initial game state
farm = [[None, None, None, None, None],
[None, None, None, None, None],
[None, None, 'House', None, None],
[None, None, None, None, None],
[None, None, None, None, None]]
with open(SAVE_FILE, 'r') as file:
lines = file.readlines()
for line in lines:
if line.startswith('day:'):
state['day'] = int(line.split(':')[1].strip())
elif line.startswith('energy:'):
state['energy'] = int(line.split(':')[1].strip())
elif line.startswith('money:'):
state['money'] = int(line.split(':')[1].strip())
elif line.startswith('bag:'):
bag_items = line.split(':')[1].strip().split(',')
for item in bag_items:
if item: # Check if item is not empty
parts = item.split(':')
if len(parts) == 2:
code, quantity = parts
state['bag'][code] = int(quantity)
elif line.startswith('farm:'):
farm_items = line.split(':')[1].strip().split(',')
index = 0
for r in range(5):
for c in range(5):
value = farm_items[index]
if value == 'None':
farm[r][c] = None
else:
parts = value.split(',')
if len(parts) == 2:
seed_code, growth_time = parts
farm[r][c] = [seed_code, int(growth_time)]
else:
farm[r][c] = None
index += 1
return state
else:
print('No saved game found. Starting a new game.')
return initial_game_state()
this is what i have rn

Can you paste the code using a paste link please?
thorn girder
!paste

thorn girder
yup perfect, just looking at it now
maiden holly
alright
thorn girder
I'd really consider a different format other than txt file for this
json would be perfect
maiden holly
unfortunately it has to be txt file
thorn girder
you can technically save json to a txt file 
maiden holly
lecturer said specifically not to import json 💔
maiden holly
loading
thorn girder
Does the file look like you expect it to when you save?
Can you show what the file looks like?
maiden holly
it looks smth like that
thorn girder
well this already seems like a problem here
I take it you didn't mean to split up your house like this?
maiden holly
what does it affect? cos it looks fine when i load it
thorn girder
but you just said you had issues loading
it affects not matching the format of your grid
maiden holly
but it appears to be the same?
main issue im having rn is loading the contents of the bag
thorn girder
this is a common "fix a problem that you caused" situation
the way it's saved is definitely not correct, but you've somehow forced a solution when loading it, when really, you should have avoided the saving issue in the first place
maiden holly
ic, how should i have gone abt fixing it
thorn girder
you're mapping each cell to a string, which will unpack your house string
!e
text = 'house'
print(list(map(str, text)))
:white_check_mark: Your 3.12 eval job has completed with return code 0.
['h', 'o', 'u', 's', 'e']
hmm ok gotchu

is there anything else wrong here that makes it so the seeds and their quantities dont load when i load the game?
thorn girder
what about it makes you think that it's wrong?
maiden holly
because the loading part for the seeds dont work
thorn girder
yes but what makes you think that? Is there an error?
"Doesn't work" doesn't really tell us much
maiden holly
oh, it just prints that you have no seeds rather than actually printing the quantities
mb

despite having seeds
thorn girder
have you tried printing out the state at the end of the loading logic?
maiden holly
shouldnt the return state have done that?
thorn girder
return and print are not the same thing
you can use prints to help debug your code
if it's not working as you expect, then print the data to see if it's what you expect it to be
if it isn't, then you can work your way back through the code to see where the logic has an inconsistency
maiden holly
thorn girder
it's possible it's triggering the "file not found" and you aren't realizing
maiden holly
where did you put the print btw?
at the end of the loading part
thorn girder
can you show?
thorn girder
ahh
bag_items = line.split(':')[1].strip().split(',')
it's because of this
your line is bag:LET:2
when you do line.split(':')[1], you're only taking LET
if you want everything AFTER the first split, you can do this instead
bag_items = line.split(':', 1)[1].strip().split(',')
you need the extra 1 there to tell it to only split once at the first :
but also notice how there's no farm in your state
{'day': 1, 'energy': 7, 'money': 13, 'bag': {'LET': 2}, 'seeds': 0}
because that also isn't being saved properly
oh nm farm is separate
[[None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None]]
either way I get this for farm
maiden holly
```
[[None, None, None, None, None], [None, None, None, None, None], [None, None...
is that why if i quit the program, the crops dont save either?
thorn girder
I'm not sure how you intended on saving the crops
oh, into the farm grid?
file.write("farm:" + ','.join(
'None' if cell is None else ','.join(map(str, cell)) for row in farm for cell in row) + '\n')
in general, I would avoid these crazy one liners
they're hard to debug
maiden holly
oh, into the farm grid?
yeah
thorn girder
I would start by creating a separate function for returning a string that represents your farm
farm:None,None,None,None,None,None,None,None,None,None,None,None,H,o,u,s,e,None,None,None,None,POT,3,None,None,None,None,None,None,None
this makes it very difficult to see where each row of the farm starts
perhaps introduce a different character to separate each row
so | could separate the rows, and , could separate the items in the rows
None,None,None,None,None|None,None,None,None,None|None,None,House,None,None|None,None,None,None,None|None,None,None,None,None
def farm_to_string(farm):
data = []
for row in farm:
data.append(','.join(map(str, row)))
return '|'.join(data)
then all you need to do is file.write(farm_to_string(farm))
isn't that much cleaner?
maiden holly
yeah, it is
sorry im tryna process
ok i think i get it, but ill need to update the loading portion right?
thorn girder
give it a try and see yes, you'll need to so you can include the logic of splitting |
print is your absolute best friend to start debugging
print out lines, print out variables
before you print, think about what you expect the result to be
if it doesn't match, work backwards and figure out why
maiden holly
ok, thanks for the help 🙏 i gotta submit this in like 30 mins lol
maiden holly
if it doesn't match, work backwards and figure out why
yo sorry i uh couldnt figure out how to do the loading part 😭 it still doesnt save the crops when i kill the program and try to load the save
got any more pointers?
thorn girder
start by making sure the save looks correct
don't start on the loading feature until the save text file looks exactly how it should
maiden holly
the save correctly splits it up, but since there are [] for the crops, i put an if statement to get what was inside them
the map prints properly still but the crops just dont appear
thorn girder
show what the text file looks like
thorn girder
you'll need to come up with a better way to store things that are lists
so perhaps if it's a list, you could store it as POT:3 instead of ['POT', 3]
you're also missing the : after your farm
it says farmNone right now
maiden holly
oh yeah ok
https://paste.pythondiscord.com/77OQ
this is what ive been trying to use for the load now
thorn girder
ok so now you can check if the cell has : in it
and if it does, you know it will need to be split up
you no longer will need to check for [ or ]
maiden holly
so i just replace the check for [] with :?
thorn girder
Yes. Take a moment to think about what you actually want to do
