Change the value of an order

Question

I'm trying to change the value of a command on each run. For this I tried a prototype like this:

import os
import random
from random import random

class testShutDown :

    ticks = random.randint(10,100)
    os.system("shutdown /s /t {ticks}")

According to me, with each execution of the code, the computer must shut down randomly between 10 and 100 seconds.

Unfortunately, it doesn't work... I hope someone can help me solve this problem which seems simple to me, but not for me.

Answer 1

Did you miss the f in f-string?

f"shutdown /s /t {ticks}"

Answer 2

import os
import random
from random import random

class testShutDown :

    ticks = random.randint(10,100)
    os.system(f"shutdown /s /t {ticks}")

i think u forgot to add f before string try this. f tells that the string contains a variable.

Answer 3

You have to add the f for strings substitution. For example,

>>> name = "apple"
>>> f"My test name is {name}."
'My test name is apple.'

Therefore the solution is to modify the os line to this:

os.system(f"shutdown /s /t {ticks}")

Alternatively, you can use the format function:

os.system('shutdown /s /t {}'.format(ticks))

Also, you should just use import random instead of from random import random.
