Python Program to generate a Random String
A random refers to the collection of data or information that can be available in any order. The random module in python is used to generate random strings. The random string is consisting of numbers, characters and punctuation series that can contain any pattern. The random module contains two methods random.choice() and secrets.choice(), to generate a secure string. Let's understand how to generate a random string using the random.choice() and secrets.choice() method in python.
The random.choice() function is used in the python string to generate the sequence of characters and digits that can repeat the string in any order.
Create a program to generate a random string using the random.choices() function.
Following are the method used in the random module to generate the random string.
Generate a random string of upper case and lower-case letters
Random String of Specified Characters
Note: The random.choice() method is used in the python program to repeat the same characters strings. If we don't want to display repetitive characters, we should use random.sample() function.
Generate a random string without repeating the same characters
As we can see in the above output, the random.sample() method returns a string in which all characters are unique and non-repeating. Whereas, the random.choice() method returns a string that may contain repetitive characters. So, we can say that if we want to generate a unique random string, use random.sample() method.
Generate a random alphanumeric string consisting of fixed letters and digits
For example, suppose we want a randomly generated alphanumeric string that contains five letters and four digits. We need to define these parameters into the function.
Let's write a program to generate an alphanumeric string that contains a fixed number of letters and digits.
A secrets.choice() method is used to generate a more secure random string than random.choice(). It is a cryptographically random string generator that ensures no two processes can obtain the same results simultaneously using secrets.choice() method.
Let's write a program to print a secure random string using the secrets.choice method.
Use the different method of the random module to generate a safe random string.
Let's write a program to print secure random strings using different methods of secrets.choice().
