Why do 'return bool' show different results in command prompt vs IDE

Question

If I try the below code in command prompt , I get correct results, however, the same code using IDE(Atom) do not produce any results.

def search_for_vowels(word):
    """Display any vowels found in an asked for word"""
    vowels = set('aeiou')
    found = vowels.intersection(set(word))
    return bool(found)

search_for_vowels('galaxy')

Most terminal will automatically display returned values, python scripts will not. Perhaps you meant `print(search_for_vowels('galaxy'))`? — Henry Ecker, Sep 18 '21 at 20:01
How do you know it doesn't produce results? It doesn't _print_ anything, but that's not the same thing. — John Gordon, Sep 18 '21 at 20:06
@HenryEcker - Thanks, it works, but what exactly was wrong in my code. If you can bit elaborate, how can I call this function and get the return value printed at the same time. — Praveen Paliwal, Sep 18 '21 at 20:08
@JohnGordon- Even for words with no vowel/s, it gives the same result: prints nothing — Praveen Paliwal, Sep 18 '21 at 20:09

Using the command prompt to code is different than using IDE. When you use the command prompt you use something called interpreter, it will execute every line you write right after you click enter. You can write an object like that:

search_for_vowels('galaxy')

And it will print its __repr__ to the screen. In IDE it is not the case. It won't print you the __repr__ of an object just be writing it. If you want to see the object or the function call result use print like that:

print(search_for_vowels('galaxy'))
