Generating strings from (for example) lowercase characters:

<pre><code>import random, string

def randomword(length):
 letters = string.ascii_lowercase
 return ''.join(random.choice(letters) for i in range(length))
</code></pre>

Results:

<pre><code>&gt;&gt;&gt; randomword(10)
'vxnxikmhdc'
&gt;&gt;&gt; randomword(10)
'ytqhdohksy'

blocks|key|1364208|text|由于这个问题是相当的，呃，随机的，这可能对你有用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1364209|>>>+import+uuid

Since this question is fairly, uh, random, this may work for you: 

<pre><code>&gt;&gt;&gt; import uuid
&gt;&gt;&gt; print uuid.uuid4()

blocks|key|1364092|text|您可以构建随机ascii字符，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1364093|import+random
print+chr(random.randint(0,255))|code-block|syntax|javascript|1364094|然后构建一个更长的字符串，如：|1364095|len+=+50

You can build random ascii characters like:

<pre><code>import random
print chr(random.randint(0,255))
</code></pre>

And then build up a longer string like:

<pre><code>len = 50
print ''.join( [chr(random.randint(0,255)) for i in xrange(0,len)] )
</code></pre>

blocks|key|1149171|text|关于你需要什么样的随机字符串，你并没有说太多。但在任何情况下，您都应该研究一下random模块。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1149172|下面粘贴了一个非常简单的解决方案。|1149173|import+random

def+randstring(length=10):

You haven't really said much about what sort of random string you need. But in any case, you should look into the <code>random</code> module.

A very simple solution is pasted below.

<pre><code>import random

def randstring(length=10):
 valid_letters='ABCDEFGHIJKLMNOPQRSTUVWXYZ'
 return ''.join((random.choice(valid_letters) for i in xrange(length)))

print randstring()
print randstring(20)

Sometimes, I've wanted random strings that are semi-pronounceable, semi-memorable.
<pre><code>import random

def randomWord(length=5):
 consonants = &quot;bcdfghjklmnpqrstvwxyz&quot;
 vowels = &quot;aeiou&quot;

 return &quot;&quot;.join(random.choice((consonants, vowels)[i%2]) for i in range(length))
</code></pre>
Then,
<pre><code>&gt;&gt;&gt; randomWord()
nibit
&gt;&gt;&gt; randomWord()
piber
&gt;&gt;&gt; randomWord(10)
rubirikiro
</code></pre>
To avoid 4-letter words, don't set <code>length</code> to 4.

How do you create a random string in Python?

I needed it to be number then character repeat till you're done this is what I created

<pre><code>def random_id(length):
 number = '0123456789'
 alpha = 'abcdefghijklmnopqrstuvwxyz'
 id = ''
 for i in range(0,length,2):
 id += random.choice(number)
 id += random.choice(alpha)
 return id
</code></pre>

Random strings in Python

如何在Python中创建随机字符串？我需要它是数字，然后重复字符，直到你完成，这是我创建的def random_id(length):    number = '0123456789'    alpha = 'abcdefghijklmnopqrstuvwxyz'    id = ''    for i in range(0,length,2):        id += random.choic
