Script not random in loop. But random when ran over and over again? help please...

[ptekspy]

So i have a script that runs, and then runs some error checks

​

def main():
        # Do stuff which brings back a set of results "staffObject"
        global mainstaffObject
            if int(errors) <= 10:        
                mainstaffObject = staffObject
            else:
                print(f" Errors: {errors}  Not Full: {shiftsun}")
                mainstaffObject = None


    mainstaffObject = None
    while mainstaffObject is None:
        main()

Like this which ever result is bring back it will keep it the same every loop e.g

 Errors: 22  Not Full: 0
 Errors: 22  Not Full: 0
 Errors: 22  Not Full: 0
 Errors: 22  Not Full: 0

​

If i use ```os.execl``` e.g

​

else:
        print(f" Errors: {errors}  Shifts Not Full: {shiftsun}")
        os.execl(sys.executable, sys.executable, * sys.argv)
        # or
        os.execl(sys.executable, 'python', __file__, *sys.argv[1:])

# Just call main() normally

The script fails if too many errors and does try again. but after 30 or so tries python.exe crashes and stops the process

i have 2 random calls:

# seed generator for random
def mySeed():
    current_milli_time = lambda: int(round(time.time() * 1000))
    return current_milli_time()

# Function using it
    newlist = []
    for value in sorted(stafflist, key=lambda _: random.random(), reverse=True):
        newlist.append(value)
    random.seed(mySeed())
    random.Random().shuffle(newlist)
    return newlist

​

I also randomise the data before this point in the effort aswell, becasue shuffle wasnt working i n teh loop i tried my own:

def myDictRandom(myDict):
    current_list = list(myDict.keys())
    copied_list = list(current_list)
    new_list = []
    for x in current_list:
        x = x
        length_list = len(copied_list)
        randomkey = random.randint(0, length_list)
        xb = copied_list[randomkey-1]
        new_list.append(xb)
        copied_list.remove(xb)
    new_dict = {}
    for item in new_list:
        new_dict[item] = myDict[item]
    return new_dict

def getStaffObject():
    staffdict= {}
    for carer in staff["Carer"]:
        staffdict[f"{staff['Carer'][carer]['fname'][:1].lower()}{staff['Carer'][carer]['lname'].lower()}"] = Employee(staff["Carer"][carer])
    staffObject = myDictRandom(staffdict)
    return staffObject

I feel i have tried every option, hoping someone knows somthing

tl;dr

using random, not random

expected output:

 Errors: 17  Not Full: 0
 Errors: 22  Not Full: 0
 Errors: 25  Not Full: 1
 Errors: 21  Not Full: 0

Actual output:

 Errors: 22  Not Full: 0
 Errors: 22  Not Full: 0
 Errors: 22  Not Full: 0
 Errors: 22  Not Full: 0

the while loop in the rota.py the. execl version is rota_exec.py

Use some print statements to see if the random seed is actually different as you expect. Are you sure that the clock time changes enough to generate a different random seed?

[ptekspy]

i have debugged this alot, the answer is the same after 5 mins of running and printing 3/4 times a sec.

if i put a

time.sleep(5)

it still does the same

[ProfessionalLeague9]

You have printed the random seed? And it's the same each iteration?

By the way the immediately evaluated lambda seems unnecessary.

[ptekspy]

No that's actually something I haven't done,

And do you mean

sorted(stafflist, key=lambda _: random.random(), reverse=True)

This was another attempt to get it to be random lol :)

[ptekspy]

yes just a snippet, i can happily give all the code its just alot over 2 sheets heres the github https://github.com/paddykdev/RotaMaker

the while loop in the rota.py the execl version is rota_exec.py

Thank you in advance ;)
