python生成五位随机数,Python-5位无重复数字的随机数生成器

I am supposed to print a random 5-digit number with no repeating digits, then ask the user for a three digit number. If the user's number contains three digits from the random number, print "correct".

I am using this code for the random number

num = random.randint (0,99999)

print (num)

The problem is it will not always print a five digit number.

Also, I don't know how to match the user number with the random number.

Thank you.

Take a random sample of the digits 0 to 9:

''.join(random.sample('0123456789', 5))
