In many cases we may need to generate random strings.

Python also provides methods and functions for generating random strings.

This function is choice, a function defined in the Random library.

Usually choice will pick one of the given strings.

According to Python’s official definition of strings in String.py.

whitespace = ' \t\n\r\v\f' ascii_lowercase = 'abcdefghijklmnopqrstuvwxyz' ascii_uppercase = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'  ascii_letters = ascii_lowercase + ascii_uppercase digits = '0123456789' hexdigits = digits + 'abcdef' + 'ABCDEF' octdigits = '01234567' punctuation = r"""!" # $% & '() *, +, -. / :; The < = >? @[\]^_`{|}~""" printable = digits + ascii_letters + punctuation + whitespaceCopy the code

The above strings are ASCII strings you can use at any time.

When the choice(string.ascii_uppercase) method is called, it means that a character will be randomly selected from uppercase characters.

What if we want a random string of six lengths?

We should execute the above function six times and then concatenate the results of the six executions.

For example, we could write:

"".join([choice(printable) for x in range(int(length))])

Length is the length of the string we want to concatenate. Printable is a character that can be used to generate strings.

The structure of our code run, as shown above, is designed to test random string generation.
