Why can parenthesis cause exceptions in Python when using for loops?
- Why can parentheses cause exceptions in Python when using for loops?
Using parenthesis in Javascript is always needed when you wanted 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 parenthesis. 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 parenthesis it will work again. Is this because the parenthesis that acts as a tuple prevent the for...in loop to iterate over the list and set a value from the list to fruit? Which makes it not possible to be printed?
