Python program to Generate a Random String

Python program to Generate a Random String

To generate a random string in Python, you can use the random module and the string module.

Here is an example of how to generate a random string of length 10, containing only lowercase letters:

import random
import string

def generate_random_string(length):
    return ''.join(random.choices(string.ascii_lowercase, k=length))

random_string = generate_random_string(10)
print(random_string)

Output

In this example, the random.choices() function is used to choose 10 random lowercase letters from the string string.ascii_lowercase, which contains all the lowercase letters in the ASCII character set. The join() function is then used to join the randomly chosen letters into a single string.

You can modify the above code to generate random strings of other lengths or containing other characters. For example, you can use string.ascii_uppercase to generate a string containing only uppercase letters, or string.digits to generate a string containing only digits. You can also combine these character sets to generate strings containing a mixture of different characters.

import random
import string

def generate_random_string(length):
    characters = string.ascii_lowercase + string.ascii_uppercase + string.digits
    return ''.join(random.choices(characters, k=length))

random_string = generate_random_string(10)
print(random_string)

Output

Note that the random strings generated using this method are not truly random, as they are generated using a pseudo-random number generator. If you need to generate truly random strings, you can use a hardware random number generator or a secure random number generator provided by the secrets module.
