i want to random
x = 1234
the function should chose any number from x
for example
random.function (x) = 3
is there a way

Is this what you mean? - >>> import random
-
>>> random.choice([1,2,3,4,5,6,7,8,9,0])
-
2
-
>>>
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
function .... in ur case we can do it as : - import random
-
random_choice=random.choice(str(x))
<Enter a four digit number:1234>
<choose operation (1)Addition (2)Subtraction (3)Multiplicati on (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

Someone once posted the following macro on clc:
#define randint(a,b) (a)+(((b)-(a)+1)*(float)rand()/RAND_MAX)
Unfortunately it's flawed. If rand() returns RAND_MAX the result can be
one larger than b.
So can someone provide a *proper* macro (or function) that returns a
random integer between (actually in) a range of values? For example
randint(0, 999) could return:

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
