python上获得随机字符

import random
import string

print(string.ascii_letters)  # 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
print(string.ascii_lowercase)  # 'abcdefghijklmnopqrstuvwxyz'
print(string.ascii_uppercase)  # 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

print(string.digits)  # '0123456789'
print(string.hexdigits)  # '0123456789abcdefABCDEF'
print(string.octdigits)  # '01234567'
print(string.printable)  # '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
			 # !"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c'

print(string.punctuation)  # '!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'
print(string.whitespace)  # '\t\n\x0b\x0c\r '

print("".join(random.choice(string.printable) for x in range(10)))  # zrZqU~?e}M

print("".join(random.sample(string.ascii_letters, 5)))  # sBvLt

print("".join(random.sample(string.ascii_letters + string.digits, 8)))  # s5T30DY9
