"""今天写一个程序,在想既然可以获得随机数,那我可不可以获得任意字符呢,于是在stackoverflow.com 上找到了方法,几乎都是用导入random,然后再用其它方法间接实现随机字符。
现在总结如下:"""
#获取单个
>>> import random
>>> import string
>>> random.choice(string.ascii_lowercase)
'b'
>>> import string
>>> string.letters
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>> import random
>>> random.choice(string.letters)
'j'
import random
def guess_letter():
return random.choice('abcdefghijklmnopqrstuvwxyz')
import string #This was a design above but failed to print. I remodled it.
import random
irandom = random.choice(string.ascii_letters)
print irandom
#获取一串:
>>>def random_char(y):
return ''.join(random.choice(string.ascii_letters) for x in range(y))
>>>print (random_char(5))
>>>fxkea
可以简化为:''.join(random.sample(string.ascii_lowercase,5))
import string
import random
KEY_LEN = 20
def base_str():
return (string.letters+string.digits)
def key_gen():
keylist = [random.choice(base_str()) for i in range(KEY_LEN)]
return ("".join(keylist))
You can get random strings like this:
