关于python：如何生成随机字符串？


How to generate random string?

本问题已经有最佳答案，请猛点这里访问。

我只是想问一下，比如从：Random.randint(a, b)中取随机数。

我只想问一下，如何像randint一样取随机字符串，但这次是用随机字符串。还有吗？

这是一个小游戏，要求你输入6个名字，然后游戏会猜到你输入的6个数字之间的一个数字，但它总是给我一个错误。希望使用随机字符串。

你好，Husnain先生，

CR()函数

CHR(I)返回表示其Unicode码位为整数i的字符的字符串。例如，chr(97)返回字符串"a"，而chr(8364)返回字符串"€"。这与ORD()相反。

参数的有效范围是从0到1114111(以16为基数为0x10ffff)。如果超出该范围，将引发ValueError。

我希望我的回答有帮助。如果有任何疑问，请评论。

更新：

对于您描述的特定情况，您可以简单地创建一个包含您允许的所有字符的字符列表。然后，您可以使用该命令创建长度为X的单词(替换为实际长度：

1
2
3
base_chars = [ 'a', 'b', 'c', '1', '2', '3' ]
word_length = 10 #change this to the desired word length
[random.choice(base_chars) for _ in range(word_length)]

原件：随机字符串-定义字符

您应该首先决定要使用哪种字符。例如，如果您想使用0到127之间的ASCII字符，或者只使用A-Z和A-Z字符，还需要考虑数字、空格等，因此您应该首先确定要从中随机选择的字符集。

随机选择角色

如果要在ASCII表中使用0到127范围，则可以使用此选项：

char = chr(random.randint(0, 127))

生成随机词

现在，要创建一个单词，首先应该确定它的大小。这也可以是随机的。例如，我们将随机选择一个单词的大小(范围有限)：

1
2
3
rand_str =""
for _ in range(10):
     rand_str += chr(random.randint(0, 127))

我建议使用一个包含输入名称的列表，而不是将名称保存到不同的变量中。它可能看起来像这样：

1
2
3
4
5
6
name_list = []
print('Please enter the first name in letters')
name_list.append(input())
print('Please enter the second name in letters')
name_list.append(input())
...

然后可以使用random.choice随机选择一个列表项，例如

1
2
import random
secretname = random.choice(name_list)

试试这个，

1
2
3
4
import string
alpha = string.ascii_uppercase
num = string.digits
''.join(random.choice(alpha + num) for _ in range(5)) #number you want

您可以使用random.randint：

1
2
3
my_string ="abcdefghijklmnopqrstuvwxyz"
index = random.randint(0,25)
letter = my_string[index]

你只要把它循环一下，就可以用字母造出字符串。
