About create tuples

Question

Why can I create tuple in this way,

tup = (777)

but not in that way?

tup = tuple(777)

Answer 1

your first example does not create a tuple.
your second example gives an error because we must pass an iterable to tuple().

some examples:

x = (7) # int
print(x, type(x))

x = (7,)
print(x, type(x)) # tuple

x = tuple((7,))
print(x, type(x)) # tuple

x = tuple(7) # error as constructor expects an interable
print(x, type(x))

Answer 2

Hey! 😃

I see you’re trying to create a tuple in Python.
Here’s the thing:

tup = (777) is NOT a tuple, it's just the number 777.
Check it: print(type(tup)) # <class 'int'>

To make a tuple with one item, you have two ways:

1️⃣ Using a comma inside parentheses:
tup = (777,)

2️⃣ Using tuple() on an iterable (like a list):
tup = tuple([777])

Tip: In Python, parentheses alone don’t make a tuple—**the comma does!**

Good luck with learning Python, it’s an awesome language! 👍

Answer 3

tuples always have to have the comma. even 1 element needs a comma. no comma, no tuple.
