Tuple

Similar to Python tuples, but you have to define the type for each element and cannot iterate over them.

These are meant to be containers for multiple values, useful for returning multiple values from a function/method.

Declaration

Same as Python

def pseudo_fn():
    a: tuple[int, float, str] = (1, 1.2, "a")

Accessing an element

Unfortunately, you cannot use the [] operator to access an element. Instead, you use the tg function:

from pypp_python import tg


def pseudo_fn(t: tuple[int, float, str]):
    index: int = 1
    value: float = tg(d, index)

tg standard for 'tuple-get'

Unpacking elements

Same as Python

from my_module import create_len_2_tuple_fn


def pseudo_fn(t: tuple[int, float, str]):
    # from a variable
    a, b, c = t

    # from a function call
    u, v = create_len_2_tuple_fn()

Methods

The two Python tuple methods are supported in Py++ and documented in the Python docs

• count
• index

Other operations

• in, not in
• ==, !=
• <, >, <=, >=
• len()
• print()
