Errors with using functions and print?

So, when I was messing around with studio, I decided to make a small game. I made a script to return the Players in the "Players" menu in the Explorer.

I used print to check if the script was working, however, when I ran the game, an error popped up in the output that said " Workspace.Script:3: function arguments expected near 'print' ".

In case you were wondering, this was the test script I used:

local returnedPlayers = game.Players:GetPlayers

print(returnedPlayers) -- printed the table

Then I tried to use functions to fix the issue:

local returnedPlayers = game.Players:GetPlayers

function testPrint() -- the function
	print(returnedPlayers) -- printed the table
end

testPrint() -- calls the function

But the error still persisted. (The only difference was "print" was changed into "function".) However, when I first used studio, it worked fine. Can someone explain what changed or what I am doing wrong?

Since this is a table, I would recommend using a for loop. This should work ~~~~~~~~~~~~~~~~~

local returnedPlayers = game.Players:GetPlayers()
for _,i in pairs(returnedPlayers) do
print(i.Name)
end
