Random Choice Operations

[Souls99]

The problem here is i successfully pick a random number from list but when i want o divide that number to 2 just like last lane of my code python chooses other random number and divide that number to 2
Thanks in advance for answers.


forum. ie.

import random
numberList = [2,4,6,8,10]
random_num = random.choice(numberList)
print(random.choice(numberList))
print("result is : " + str(random_num))/2

Your code is trying to divide the print statement by 2

Error:
TypeError: unsupported operand type(s) for /: 'NoneType' and 'int'

Using f string formating

print(f'result is : {random_num/2}')

still python chooses new number and divide the new number , in my code i successfully divide the random number to 2 but the problem it chooses new number i need the first chosen random number look i changed the code as u said
forum. ie.

numberList = [2,4,6,8,10]
random_num = random.choice(numberList)
print("additional: ", + random.choice(numberList))

input("division 2")
input("Subtract the first number you have chosen")
print("Hmmm  let me think")
time.sleep(2)
print("Result issss")
print(f'result is : {random_num/2}')

result
additional: 10
division 2
Subtract the first number you have chosen
Hmmm let me think
Result issss
result is : 1.0
last result is 1.0 which should be 5 because additional is first random choice number which is 10 so our code sohuld give us 5 but it didnt

I don't understand what you are trying to do.
You will have two different random numbers as you have used random.choice(numberList) twice.

Could you explain in non python code what you are trying to achieve.

i want to make python chose a random number after i want to print some text than i want to print that chosen number, for example :

random.choice = 5
hello world
tnx yoriz
print the random choice number (here i want python to print me the 5 again )

but each time i try to do that python choose new number i just want to print the First chosen number again

Obtain the random choice once only

import random

numberList = [2, 4, 6, 8, 10]
random_num = random.choice(numberList)

print(f'random.choice = {random_num}')
print('hello world')
print('tnx yoriz')
print(('the random choice number '
       f'(here i want python to print me the {random_num} again)'))

Output:
random.choice = 4
hello world
tnx yoriz
the random choice number (here i want python to print me the 4 again)

input("times 2")

numberList = [2,4,6,8,10]
