Trying to randomize students creatures in TeacherStudentsScene but it shows same students every time when i render

[NavpreetDevpuri]

I created new creatures named

• PlusCreature
• MinusCreature
• MultiCreature
• DivCreature
• RemCreature
• AndCreature
• EqualCreature
• RoundBracketsCreature
• CurlyBracketsCreature
• SquareBracketsCreature
• AngleBracketsCreature
• HashCreature
• QuestionCreature
  Creatures are looks like
  

and added this creatures to the file c_creature (renamed pi_creature) for example this one

class PlusCreature(CCreature):
    CONFIG = {
        "file_name_prefix": "PlusCreatures"
    }

and i changed method 'create_c_creatures()' in class TeacherStudentsScene in file c_creature_scene.py (renamed pi_creature_scene.py)

    def create_c_creatures(self):
        self.teacher = CCreature(color=self.teacher_color)
        self.teacher.to_corner(DOWN + RIGHT)
        self.teacher.look(DOWN + LEFT)
        '''From that
        self.students = VGroup(*[
            Randolph(color=c)
            for c in self.student_colors
        ])
        '''
        # To this
        print("yessssss its runing, we are creating students.")
        self.students = VGroup(*[
            random.choice([PlusCreature,
                          MinusCreature,
                          MultiCreature,
                          DivCreature,
                          RemCreature,
                          AndCreature,
                          EqualCreature,
                          RoundBracketsCreature,
                          CurlyBracketsCreature,
                          SquareBracketsCreature,
                          AngleBracketsCreature,
                          HashCreature,
                          QuestionCreature])(color=c)
            for c in self.student_colors
        ])
        self.students.arrange(RIGHT)
        self.students.scale(self.student_scale_factor)
        self.students.to_corner(DOWN + LEFT)
        self.teacher.look_at(self.students[-1].eyes)
        for student in self.students:
            student.look_at(self.teacher.eyes)
        return [self.teacher] + list(self.students)

i created file manimlib.imports_with_c that imports c_creatures instead of pi_creatures
when i run following code ( i tried self.setup() and self.c_creatures = VGroup(*self.create_c_creatures()) but this lines just create another creatures onto previouse ones)

from manimlib.imports_with_c import *
class ts(TeacherStudentsScene):
    def construct(self):
        #self.setup()
        #self.c_creatures = VGroup(*self.create_c_creatures())
        self.teacher_says( 
            "Something different today!",
            run_time = 2
        )

Output always shows same students with two EqualCreatures and one QuestionCreature even when rendering code again and again but according to changes in method 'create_c_creatures()' in class TeacherStudentsScene in file c_creature_scene.py it should be create random creatures everytimes i run the code

same output is following

it always print the output from line print("yessssss its runing, we are creating students.") in create_c_creatures() method that means it runs every time between multiple renders. this mean may be there is something wrong with random.choice() method
but i tried following code.

import random
def a1():
    return "1"
def a2():
    return "2"
def a3():
    return "3"
def a4():
    return "4"
def a5():
    return "5"
numbers = [*[random.choice([a1,a2,a3,a4,a5])() for i in range(0,20)]]
print(numbers)

it allways print random numbers.

but when i put this code inside create_c_creatures() like follow

 print("yessssss its runing, we are creating students.")
        self.students = VGroup(*[
            random.choice([PlusCreature,
                          MinusCreature,
                          MultiCreature,
                          DivCreature,
                          RemCreature,
                          AndCreature,
                          EqualCreature,
                          RoundBracketsCreature,
                          CurlyBracketsCreature,
                          SquareBracketsCreature,
                          AngleBracketsCreature,
                          HashCreature,
                          QuestionCreature])(color=c)
            for c in self.student_colors
        ])
        def a1():
            return "1"
        def a2():
            return "2"
        def a3():
            return "3"
        def a4():
            return "4"
        def a5():
            return "5"
        numbers = [*[random.choice([a1, a2, a3, a4, a5])() for i in range(0, 20)]]
        print(numbers)

now it always shows same numbers.

then whats wrong with my code ? why always same students ?

it solved by putting random.seed()

random.seed()
self.students = VGroup(*[
            random.choice([PlusCreature,
                          MinusCreature,
                          MultiCreature,
                          DivCreature,
                          RemCreature,
                          AndCreature,
                          EqualCreature,
                          RoundBracketsCreature,
                          CurlyBracketsCreature,
                          SquareBracketsCreature,
                          AngleBracketsCreature,
                          HashCreature,
                          QuestionCreature])(color=c)
            for c in self.student_colors
        ])

following code is for selecting creatures without repetition

random.seed()
        temp = random.sample(
            [PlusCreature,
             MinusCreature,
             MultiCreature,
             DivCreature,
             RemCreature,
             AndCreature,
             EqualCreature,
             RoundBracketsCreature,
             CurlyBracketsCreature,
             SquareBracketsCreature,
             AngleBracketsCreature,
             HashCreature,
             QuestionCreature], len(self.student_colors)
        )
        self.students = VGroup(*[
            i(color=c)
            for c,i in zip(self.student_colors,temp)
        ])
