How to generate random password string in Python


How to generate random password with Python programming language ? Ok, i will introduce you a good way with some neccessary modules to make a strong password (digits + upper character + lower character), the min length of password string will be 8. In this post, i will use Python 2.7 syntax for example, if you choose Python 3.x you need to search document of module.

1. Using module string python

– Let’s import module string.

– Print a string contains all alphabet characters.

– Print all special characters.

– Print a string contains numbers.

– In this post, i will exclude all special characters in operation of generating random password ? Why ? Because in some OS or applications, they dont accept almost of special characters so we dont need them so much for inconvenience.

– Howerver, what we will do next ? We just have few list of needed character for combining operation to make a strong password. Ok, next step we will use module ‘random‘ in Python to make a bit interesting action.

2. Using module random python

– Module random in python supports you a lot of useful method for any case like generate random digit, choice an object in list,… in this post we will only need to use method pick a random character once time.

– Go to this time, i think we can imagine how sample code will work to create a random password.

3. Sample code to generate random password

– In this case, i will fix the min size and max size for length of password (from 8 -> 15).
– Run loop ‘for‘ and extract random character in database pre-defined characters. After that, concentrate all of extracted character together without any delimiter.


Very easy right, now you can use above code to deploy a function for generate random password. Just do it by yourself.
