remove the spaces

lower_a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l',

开发者_运维百科What I want to do is remove the spaces from the output. What it gives now is:

Z 3 a A I K R
G B i N 9 c E
v g E r A N 8
e B 6 d v H O
c a V 8 c x y
b g 2 W a T T
f 8 H T r 6 E
p D K l 5 p u
x q 8 P Z 9 T
n I W X n B Q

Putting it all together with the string module.

import random
import string

chars = string.ascii_uppercase + string.ascii_lowercase + string.digits

for row in range(10):
    print ''.join(random.choice(chars) for col in range(7))

instead of:

 for i in range(7):
  a = random.choice(all)
  print a,
 print

you could do this:

 print "".join(random.choice(all) for x in range(7))

nevermind - i fixed it

while x < 10:
    y = []
    for i in range(7):
        a = random.choice(all)
        y.append(a)
    print "".join(y)
    x += 1

The space is placed by print a,. A comma following print statement print a space.
