# Problem with task 3 Python Basics

I'm unable to do task 3 :'( and I've no idea how to have the right answer ! I don't understand...

days_alive.py
```age = int(23)

days = int(23*52*7)

summary =
```

Hi Lucie

Task 3 asks you to create a variable named summary where you substitute the {} for your variable days. As stated above this is done using the format method of the string function. On another note you don't need to convert your values to integers as the compiler will pick this up automatically. So only convert datatypes when you have the following scenario. For example you would attempt to convert from a string to integer when you have something like this a=23 and b="25" and c= a * b which would throw an error as b is a string a not an integer. So the correct approach would be c = a * int(b).

```age = 23

days = 23*52*7

summary = "I am {} days old!".format(days)
# you could convert days to a string if you wanted to but its not needed.
```

hope this helps a bit with datatypes as well.

```summary = "I am {} days old!".format(days)
