Why can parentheses cause exceptions in Python when using for loops?

+6
−4

Using parentheses in Javascript is always needed when you want to create functions, if/else statements and for/while loops. But in Python it has a function that is called tuples. When using an if statement for example, it won't be a big deal when I use parentheses. But when it comes to for...in loops it seems to cause exceptions. For example,

fruits = ["Apple", "Banana", "Orange"]
for (fruit in fruits):
    print(fruit)

This will return an exception, SyntaxError: invalid syntax

But when I remove the parentheses it will work again. Is this because the parentheses that act as a tuple prevent the for...in loop from iterating over the list and setting a value from the list to fruit? Which makes it not possible to be printed?
