首页 / 操作系统 / Linux / 在Python上获得随机字符

"""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 randomKEY_LEN = 20def 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:g9CtUljUWD9wtk1z07iF
