Do keep this in mind while you practice using the methods with other string contents.If you’ve ever needed a random number, string, or slice index from your Hugo website, this post has you covered. However, which method you use would largely depend on your use case.Ī common mistake I have seen beginners make is forgetting to import the module before they use it. Hence we use a loop and get the range to the number of characters.Ĭlosing thoughts - Generate random string python:īoth methods can be used to generate a random string in Python.

choices method which takes a second argument. Print(''.join(secrets.choice(string.ascii_uppercase + string.ascii_lowercase) for i in range(7))) Secrets are very similar to the random method, you can read more about it here. This method makes use of the secrets & string methods. Python versions 3.6 and greater have a better way to generate a cryptographically secure random string. Hence it is not recommended while creating temp passwords. While we could use the random method to generate random string in Python, the string generated is not cryptographically secure.

Please feel free to try it out using the random.sample as well. Also, in all the methods I have used the random.choices. I haven’t provided output snippets as my output would vary from yours. Print(''.join(random.choices(string.ascii_uppercase + string.ascii_lowercase, k=5))) Print(''.join(random.choices(string.ascii_letters, k=5)))Ĭoncatenating different types of string constants: import random Print(''.join(random.choices(string.ascii_uppercase, k=5))) Random string in uppercase: import random Let us try the letters constantly, we can also concatenate two different types of constants. In the previous method, we used string.ascii_lowercase. This method returns a list of characters, and hence we use the join method to convert it into a string. Print(''.join(random.choices(string.ascii_lowercase, k=5)))įor this, we pass another argument ‘k’ which denotes the size of the string.

Now let us write the code to generate a string of length 5. You can change the string constant method based on the characters you want. This code generated returns one character at random. Print(random.choices(string.ascii_lowercase)) The syntax to use both the modules is as follows. So while generating a random string in Python, If you are okay with repeating characters you can use the first method, and the second if you want unique characters.

Random.sample - returns unique elements.

Random.choices - returns elements at random.

However, there are two important sequences that you should be aware of: We use this method to pick characters from the string constant. The random module is quite straightforward. However, you can view the entire list on the module documentation ( String module). I have listed the most commonly used string constant.

String.punctuation - returns a string containing punctuations.

String.digits - returns a string containing digits.

String.ascii_uppercase - returns a string with letters in uppercase.

String.ascii_lowercase - returns a string with letters in lowercase.

String.ascii_letters - returns a string of letters containing various cases.

Although they serve a large number of use cases, the most common ones are random placeholder usernames, random phone numbers, passwords, etc.īefore we use the string module to generate a random string, let us look at the various types of string constants available. Random strings are commonly generated and used widely. In the last method, we would be using the secrets module to help us generate cryptographically secure strings. The random module on the other hand is used to generate pseudo-random values. The string module contains Ascii string constants in various text cases, digits, etc. Importing string and random modules: In order to generate random strings in Python, we use the string and random modules.
