This is just standard Python list comprehension. It's a different way of writing a longer for loop. You're looping over all the characters in your string and putting them in the list if the character is a digit.

See this for more info on list comprehension.

Using a for loop, you would get the same result with:

numbers = []
for x in text:
    if x.isdigit():
        numbers.append(x)
