 ## Modules
 
 ### What is a Module
 
-A module is a file containing a set of codes or a set of functions which can be included to an application. A module could be a file containing a single variable, or a function, a big code base.

 1. Writ a function which generates a six digit/character random_user_id.
    ```py
      print(random_user_id());
      '1ee33d'
    ```
 2. Modify the previous task. Declare a function named user_id_gen_by_user. It doesn’t take any parameters but it takes two inputs using input(). One of the inputs is the number of characters and the second input is the number of IDs which are supposed to be generated.
