# Coding challenge - Currency converter
I would like you to write a program that converts EUR to DOLLAR.
You should do this in a **new** python file.
I suggest you call it `euro_to_dollar.py` or something that makes sense to you.
The result of this program *could* be as follows.
```bash
➜ python_course_doc git:(master) ✗ python3 test.py
How much EUR would you like to convert into DOLLAR? 140
140 EUR is 159.6 DOLLAR
➜ python_course_doc git:(master) ✗ python3 test.py
How much EUR would you like to convert into DOLLAR? blablabla
That's not a number I understand...
➜ python_course_doc git:(master) ✗
```
<details>
<summary>Spoiler warning</summary>
```python
result = input("How much EUR would you like to convert into DOLLAR? ")
rate = 1.14
if result.isdigit():
eur = int(result)
dollar = eur * rate
print("{} EUR is {} DOLLAR".format(eur, dollar))
else:
print("That's not a number I understand...")
```
