random integers to have speficic value

[adent]

hye, i,m new in programming.
i want to random
x = 1234

the function should chose any number from x
for example
random.function(x) = 3

is there a way

[bvdet]

Is this what you mean?

>>> import random
>>> random.choice([1,2,3,4,5,6,7,8,9,0])
2
>>> 

[adent]

no it bit like this

{x = int(raw_input('Enter a four digit number:'))
 
y = raw_input("choose operation (1)Addition (2)Subtraction (3)Multiplication (4)Division  ")
 
if (y == "1"):
    su = randint(x()) +  randint(x())
    print (su)}

Yeah, surely there is a way out .... so the idea is same .. we have to choose

random.choice(<list name>)

As we know that int are not iterable so we first convert the input number into a string type and then call the

random.choice()

function .... in ur case we can do it as :

import random
random_choice=random.choice(str(x))

[adent]

<Enter a four digit number:1234>
<choose operation (1)Addition (2)Subtraction (3)Multiplication (4)Division>
< 2>
Traceback (most recent call last):
File "C:\Users\-\main.py", line 18, in <module>
su = random_choice - random_choice
TypeError: unsupported operand type(s) for -: 'str' and 'str'

hi, i have follow ur code. but i get this error.

from random import randint
import sys
import random
 
 
x = int(raw_input('Enter a four digit number:'))
random_choice = random.choice(str(x))
 
su=0
 
#write down your logic here
y = raw_input("choose operation (1)Addition (2)Subtraction (3)Multiplication (4)Division  ")
 
if (y == "1"):
    su = random_choice +  random_choice
    print (su)
elif (y == "2"):
    su = random_choice -  random_choice
    print (su)
elif (y == "3"):
    su = random_choice *  random_choice
    print (su)
elif (y == "4"):
    su = random_choice /  random_choice
    print (su)
else:
    print ("NO")
 
print("New number is: %d" %su )

this is probably because

random_choice = random.choice(str(x))

is returning a "string" value since the input argument is of type string .... but to perform arithmetic operations, you will need to convert that back into int so the above line should look like :

random_choice = int(random.choice(str(x)))

and your overall code should go like this :

from random import randint
import sys
import random
 
 
x = int(raw_input('Enter a four digit number:'))
 random_choice = int(random.choice(str(x)))
 
su=0
 
#write down your logic here
y = raw_input("choose operation (1)Addition (2)Subtraction (3)Multiplication (4)Division  ")
 
if (y == "1"):
    su = random_choice +  random_choice
    print (su)
elif (y == "2"):
    su = random_choice -  random_choice
    print (su)
elif (y == "3"):
    su = random_choice *  random_choice
    print (su)
elif (y == "4"):
    su = random_choice /  random_choice
    print (su)
else:
    print ("NO")
 
print("New number is: %d" %su )
 
 
 

I tried it on my machine and it worked fine :) I hope it worked for u as well

thank you, it worked
