 ### Example
 
-An example of a tool which is usually installed on both Windows and Unix is ``curl``. It allows you to send HTTP requests to the internet and receive responses.
-
 If you want to know what arguments does existing program allow, the argument to use is **help**. This works for most of programs on your computer (if their author created a help page). Also usually there is a `-help` or `--help` command line argument which also shows the expected usage of a tool to any user.

-Another example of a command line tool with arguments is **find** but does different things on Windows and Linux. This example is valid for Linux:
-
-```console
-find . -type f -name "*.txt" -empty
-```
-
-Which searches current directory for empty files with .txt suffix.

-### Reading command line arguments
-
-In order to read the command line arguments, we can use the `sys.argv` variable, which gives us a list of strings, one for each passed argument:
-
-```python
-# arguments.py
-import sys
-
-for arg in sys.argv:
-    print(arg)
-```
-
-When we execute this program with the passed in arguments, we can see them printed out:
-
-```console
-python3 arguments.py some test arguments "multi word argument"
-some
-test
-arguments
-multi word argument
-```
-
-However, this is not very convenient when we want to build actual CLI programs with options and arguments. But there are good tools we can use instead!
