Bug: Declaration and Print Statements with Dictionary Key as a String type not working

[harshsingh-24]

Test Case 1 (dict_string.py):

def fun():
    y : dict[str, i32]
    y = {"apple": 1}
    print(y["apple"])

fun()

• Normal Python Output:

1

• LPython Output (when inst\bin\lpython examples/dict_string.py was executed

# NO OUTPUT WITNESSED. 

Unknown behavior of print statement was observed. Without throwing any error or warning, the program just terminates abruptly for me.

Test Case 2 (dict_string.py)

def fun():
    x : dict[i32, i32] = {1: 2}
    print(x[1])

    y : dict[str, i32]
    y = {"apple": 1}
    print(y["apple"])

fun()

• Normal Python Output:

2
1

• LPython Output (when inst\bin\lpython examples/dict_string.py was executed

code generation error: Variable type not supported 12
 --> examples/dict_string.py:5:5
  |
5 |     y : dict[str, i32]
  |     ^^^^^^^^^^^^^^^^^^

Does the dictionary has support for string data types yet or not?

Can you please verify the branch on which you are trying both the test cases? It works fine on my machine with the main branch.

% lpython a.py  # test case 2
2
1

% lpython a.py # test case 1
1

I think this is a genuine issue unrelated to dictionary , I will open a new issue.

Thanks, @faze-geek and @harshsingh-24. We will need to look into it separately.

Ohh. I thought it was happening in my machine only. 😂 That is why I closed the issue.
