For example, if you are storing some information and you need one key for that, you can create one random string and use it. In most cases, we need to create a random string. I hope you found it interesting and helpful.This tutorial will show you how to generate one secured random string of specific length in python. This article has shown how to make a random string generator in Python. If you like, go ahead and explore some different methods from the string module, to make a custom Python random string generator to meet your specific needs. This time, only lowercase letters would be used. Return ''.join(random.choices(string.ascii_lowercase, k=length)) So for another example you could do: import random To see what else the string module offers, try this (or search online): for item in dir(string): However, it provides a convenient way to access a common set of ASCII characters that is often used for generating random strings. The string module is not strictly necessary for generating a random string, as you could use any other string or character set as the population. These characters are used as the population from which the random string is generated. The string module is used in the example code to provide access to a string of ASCII letters and digits. This will generate a random string of length 10, consisting of upper and lowercase ASCII letters and digits. Print(random_string) # Output: "4Bd2zJj9圜" You can use this function like this: random_string = generate_random_string(10) Return ''.join(random.choices(string.ascii_letters + string.digits, k=length)) You can see that this gives you access to string.ascii_letters and string.digits, which you can use in your code. Take a look at the code below: import stringĪbcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ Here is a simple function that generates a random string of a given length using Python’s random and string modules. If you want to save yourself the effort of defining your population of allowable characters, you could use the built in string module. using the Python String Module to make a Random String Generator It basically takes all items in an iterable (list, tuple etc.) and joins them into one string. join() string method, which can be somewhat confusing until you get used to it. Notice that what we did here was to define a custom population for allowable characters, then use the random.choices() method with the population as a parameter, and the k value (size of result) as the length we passed in during our function call. Return ''.join(random.choices(population, k=length)) Here is one possible approach to creating a random string generator in Python: import random Writing a Random String Generator in Python Population = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789' Why not have a go for yourself before reading on, by completing the following function stub? def random_string(length): This article will show you a couple of different ways to write a random string generator in Python. There are many potential uses for a Python random string generator, depending on the specific needs of your application or project.
