Nice snippet. Did you do it this way to get the different character types with different probabilities?
Otherwise you could just put them all in one array.

I suggest doing this instead of randrange:

Code:
password += random.choice(sym)

It is more clear and you avoid the inflexibility of the hardcoded range, i.e. if you add a character to sym, you don't have to change the max value for randrange. You could also do this by using len(sym), though.

Yes.

Thanks for this info.i was not aware that there is something like random.choice.

Nice one mate, I'll add this to my code collection Smile

You could make it even more save and user-friendly by saving the password in a txt-file by doing this you could counter keyloggers in stealing you password (Just in case)

The final code would be like this (you could eventually make the program print the password too).

Code:
import random
def passgen(x):
    char='abcdefghijklmnopqrstuvwxzy'
    charup='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
    nums='0123456789'
    sym='!@#$%^&*()_+-=,<.>/?;:"{[}]|'
    password=''
    while len(password)!=x:
        if random.randrange(0,100)/2==0:
            password+=char[random.randrange(0,26)]
        elif random.randrange(0,100)/2==0:
            password+=charup[random.randrange(0,26)]
        elif random.randrange(0,100)/2==0:
            password+=nums[random.randrange(0,9)]
        elif random.randrange(0,100)/2==0:
            password+=sym[random.randrange(0,28)]
    return password

#Added Code Goes Here: 
def doc(x):
    try:
        f = open('pwd.txt', 'w')
        f.write(x)
        f.close()
        return True
    except Exception, e:
        print e
        return False

if doc(passgen(10)):
    print "Password Saved in pwd.txt."
    raw_input()
else:
    raw_input()
