Right now you're printing out everything on its own new line by using print . You can make these all into one string by storing the values in a string variable.

import random
def rand_gen1():
    output = ""
    for i in range(8):
        output += random.choice('0123456789abcdefghijklmnopqrstuvwxyz')
    print output

或者像那样（Richard Neumann用于从字符串导入）：

import random
from string import ascii_lowercase, digits

def rand_gen3():
    print(''.join(random.choice(ascii_lowercase + digits) for _ in range(8)))

rand_gen3()

You need to store the random choices in a string and then print the string:

import random

def rand_gen1():
    rand_str = ''
    for i in range(8):
        rand_str += random.choice('0123456789abcdefghijklmnopqrstuvwxyz')
    print rand_str

Each print statment creates a new line.
