extract a dictionary from a string

[berc]

Hello everyone
Please help me solve my little problem.
Created an object in canvas tkinter (canvas.create_image(bot['coord'], image = bot['image'], tags = ('bot', bot ['name'], tag1))) and passed the dictionary as a tag (tag1) - {'name': 'bot_28', 'coord': (610, 160), 'health': 0.99, 'live': 0, 'age': 0, 'speed': 0.41, 'orient': 7, 'cargo': [], 'atak': 0.521, 'radar': 25, 'step': 0, 'near': [], 'image': <PIL.ImageTk.PhotoImage object at 0x000001D3269081D0>}. The dictionary in the tag gets the string type.
Now I need to extract it, but I can't convert it back from a string to a dictionary - an error appears ('str' object has no attribute 'keys' - I wanted to see all the dictionary keys). I don't know how to fix it?

Have you tried using json.loads(string)?

bot['name']   = 'bot_' + str(i) 
bot['coord']  = coord          
bot['gender'] = random.choice(gender) 
bot['healt']  = 0.99                  
bot['gormon'] = 0.5                   
bot['live']   = 0                                        
bot['age']    = 0                                       
bot['speed']  = round((random.random()), 2)             
bot['orient'] = random.randint(0, 7)
bot['cargo']  = []                                       
bot['atak']   = round((random.random()), 3)              
tag1          = bot
bot['canvas'] = canvas2.create_image(bot['coord'], image = bot['image'], tags = ('bot', bot['name'], tag1))

...
...

collide = canvas2.find_overlapping(x1r, y1r, x2r, y2r)
if len(collide) > 1:
    i = 0
    for i1 in collide:
        if str(canvas2.gettags(collide[i])[1]) != str(bot['name']):
            vis = canvas2.gettags(collide[i])
                
            print(str(name) + '  0 vis: '+str(vis[0]))
            print(str(name) + '  1 vis: '+str(vis[1]))
            print(str(name) + '  2 vis: '+str(vis[2]))

            if vis[0] == 'bot':
                bott = vis[2]
                print(bott.keys())

Yes, I used json, I used ele... It still leaves an error

The error is pretty clear. Why do you expect bott (and hence vis[2]) to be a dict?

bot = {}     #[b]in the code snippet did not give this line, but it is[/b]
 
bot['name']   = 'bot_' + str(i) 
bot['coord']  = coord          
bot['gender'] = random.choice(gender) 
bot['healt']  = 0.99                  
bot['gormon'] = 0.5                   
bot['live']   = 0                                        
bot['age']    = 0                                       
bot['speed']  = round((random.random()), 2)             
bot['orient'] = random.randint(0, 7)
bot['cargo']  = []                                       
bot['atak']   = round((random.random()), 3)              
tag1          = bot
bot['canvas'] = canvas2.create_image(bot['coord'], image = bot['image'], tags = ('bot', bot['name'], tag1))
 
...
...
 
collide = canvas2.find_overlapping(x1r, y1r, x2r, y2r)
if len(collide) > 1:
    i = 0
    for i1 in collide:
        if str(canvas2.gettags(collide[i])[1]) != str(bot['name']):
            vis = canvas2.gettags(collide[i])
                 
            print(str(name) + '  0 vis: '+str(vis[0]))
            print(str(name) + '  1 vis: '+str(vis[1]))
            print(str(name) + '  2 vis: '+str(vis[2]))
 
            if vis[0] == 'bot':
                bott = vis[2]
                print(bott.keys())

because initially bot is a dictionary and I pass it to a tag called tag1. vis is a list of all tags retrieved by canvas2.gettags (collide [i]). vis [2] is the third tag in the list of passed tags and with 'print' it is seen as a dictionary (there are key-value pairs)

I solved this problem in a workaround way - I transfer the number of the desired bot to the function (collide_bot (number)), and then, using the bot number from the list of all bots (Bots), I extract the necessary information for a specific bot
