words = ["hello", "world", "spam", "eggs"] for word in words: print(word + "!")

Question

so question is that is the word predefined variable which directly points to the string in the list?

Answer 1

Is it predefined or is it like we can use any variable instead of word?

Answer 2

word is a variable that will point to every word in that list, as the loop goes on.

So basically as if you write:

word = words[0]
print(word+'!')
word = words[1]
print(word+'!')

... and so on.

Answer 3

You can use any word that would be okay as a variable name too (because it is one).

So you could write:

for fruit in fruitBasket:
for word in vocabulary:
for book in bookShelf:
for n in range(100):

It's totally your choice.

Whatever you choose, it just becomes a normal variable, that you can even continue to use after the loop.
