Python is a ​powerful language that allows programmers to perform various tasks using built-in libraries. A random string, for example, can be generated using the built-in libraries.
Two libraries are imported for this:
``` python
import string
import random
```

Using this `random` module, different random strings can be generated.  

`random.choice()` is used to generate strings in which characters may repeat, while `random.sample()` is used for non-repeating characters. 

|  **Method**   | **Description**    |
| --- | --- |
| `string.ascii_uppercase`    | Returns a string with uppercase characters    |
| `string.ascii_lowercase`     | Returns a string with lowercase characters     |
|  `string.ascii_letters`   |  Returns a string with both lowercase and uppercase characters   |
| `string.digits`    |  Returns a string with numeric characters   |
| `string.punctuation`    | Returns a string with punctuation characters    |


import random
import string

# printing lowercase
letters = string.ascii_lowercase
print ( ''.join(random.choice(letters) for i in range(10)) )

# printing uppercase
letters = string.ascii_uppercase
print ( ''.join(random.choice(letters) for i in range(10)) )

# printing letters
letters = string.ascii_letters
print ( ''.join(random.choice(letters) for i in range(10)) )

# printing digits
letters = string.digits
print ( ''.join(random.choice(letters) for i in range(10)) )

# printing punctuation
letters = string.punctuation
print ( ''.join(random.choice(letters) for i in range(10)) )
