Sets

Like Python sets.

Declaration

Basic

Similar to Python:

from pypp_python import auto


def pseudo_fn():
    # empty
    empty_set: auto = set[int]()

    # with some values
    short_set: set[int] = {1, 2, 3, 4}

    # from a different data structure (list, dict, or str)
    set_of_ints: set[int] = set(list_of_ints)

    # copying another set
    set_copy: set[int] = short_set.copy()

    # copying another set option 2
    set_copy_2: set[int] = set(short_set)

Set Comprehensions

Are supported in Py++. See comprehensions.

Deleting elements

Use the remove or discard method

Methods

All of the Python set methods are supported in Py++.

The methods are listed below and documented in the Python docs. - add - remove - discard - pop - clear - isdisjoint - issubset - issuperset - union - intersection - difference - symmetric_difference - update - difference_update - symmetric_difference_update - copy

Note: you can only pass temporaries or use mov() with the add method.

Other operations

Supported with the same behavior as Python:

• in, not in
• ==, !=
• len()
• min(), max()
• list()
• print()

Note: Other set operators like >, |, &, and ^, are not supported yet. For now, their corresponding methods can be used.

Iteration support

Same as Python

def pseudo_fn(colors: set[str]):
    for color in colors:
        print(color)
