Question: The error is at `script, first, second, third = argv`. I would like to understand why I am getting the error and how to fix it.

```
from sys import argv

script, first, second, third = argv
print("The script is called: ", script)
print("The first variable is: ", first)
print("The second variable is: ", second)
print("The third variable is: ", third)

```

Answer: 
Run it from the shell like this:

```
python script.py arg1 arg2 arg3

```
I think you are running the following command: 

```
python script.py

```

You are writing a program which is aksing for 4 inputs and you are giving onle one. That's why you are receiving an error. You can use the below command: 

```
python script.py Hello How Are

```
