[Compile] List, dict, and set comprehensions

[anistark]

Implement Python comprehension syntax.

Scope:

• List comprehensions ([x for x in list])
• Dict comprehensions ({k: v for k, v in dict})
• Set comprehensions ({x for x in list})
• Conditional comprehensions ([x for x in list if condition])

Dependencies: Issue #40

Acceptance Criteria:

• [x*2 for x in [1,2,3]] returns [2,4,6]
• Conditional comprehensions work
• Nested comprehensions work

hi @anistark i am struggling in testing code like where i can test if it gtg or not?
for ex:

def test_basic_list_comp():
    result = [x * 2 for x in [1, 2, 3]]
    print(result)
    


def main():
    test_basic_list_comp()
    
    print("ALL COMPREHENSION TESTS PASSED")

if __name__ == "__main__":
    main()

@dharmvr1 Do you mean how to test for list comprehension specifically or testing any python in general?

For starters, you can take a look at examples. There's lot of existing examples to test.

Waspy is a python to wasm compiler. So, you need to write a rust code which reads or imports a python code. For instance, take a look at simple_compiler.rs. It compiles basic_operations.py.
If you're looking to write similar tests, this might be helpful.
