So in this article we learned to generate a random string with upper case letters and digits using Python Programming Language. Every time we will run this code, it will print a unique string of size 10. This method helps us to create a random string with a combination of digits and alphabets in a single line of code. A combination of upper case alphabets and digits has been created using string.ascii_uppercase() and string.digits() function and it has been passed as the first argument in random.choices(). RandomStr = ''.join(random.choices(string.ascii_uppercase + string.digits, k=10))Īs you can see in code above we have used random.choices() method to generate a random string with upper case letters and digits. # Generate random string of 10 characters including only uppercase letters and digits Instead we will pass second argument k for the length of string. Also we will use same approach as used in Method 1 but this time we will not use range function. It recives a second parameter k, which denotes the length of the string. This method is same as choice() method with one difference. Next method we can use to generate a random string with upper case letters and digits is the choices() method of random module. Generate Random string with Uppercase letters and digits Using random.choices() Every time you run this code it will print a unique combination. Randomcharlst.append( random.choice(string.ascii_uppercase + string.digits) )Īs you can see in above example a combination of upper case alphabets and digits has been created and stored in randomStr. # Arguments in range() will print desired length of Python | Check if String starts & ends with same characters.Python : Find occurrence count & all indices of a sub-string in another string | including overlapping sub-strings.Python: Remove all non-alphanumeric characters from string.Check if String starts with a Lowercase in Python.At last we will use join() method to join all the chars and digits genarated with random.choice() method. We will use string.ascii_uppercase() and string.digits() functions of string method to genarate random alphabets and digits respectively. Generate Random string with Uppercase letters and digits using random.choice()įirst method we will be using to create a random string of combination of upper case letters and digits is the choice() method of random module, which comes bundled with Python. Now we will look at the methods through which we can genarate random string with upper case letters and digits. ASCII code of a to z (Lower Case) starts from 097 and ends at 122.ASCII code of A to Z (Upper Case) starts from 065 and ends at 090.It is a 7-bit character code in which every single bit represents a unique character.Įvery character in english alphabet has a unique ASCII code, It is the most used character encoding format. Generate Random string with Uppercase letters and digits Using random.choices()ĪSCII Stands for American Standard Code for Information Interchange.Generate Random string with Uppercase letters and digits using random.choice().
