调研方向

Reproduce the issue with the shown enumerate example and inspect the generated tests.enumerate.py around the py_enumerate reference. Trace how the compiler handles the enumerate primitive and compare the generated output with the runtime definitions; done means the example compiles and runs in the reported browsers without the ReferenceError.

描述

IS: bug?

I reinstalled Transcrypt today, and I encountered a weird error.

source:

def test_enumerate():
    print('in test_enumerate()')
    l= [1,2,3,4,5]
    for i, v in enumerate(l):
        print(f'{i}: {v}')

output:

in test_enumerate()
tests.enumerate.py:4 Uncaught ReferenceError: py_enumerate is not defined
    at test_enumerate (tests.enumerate.py:4:1)
    at main (tests.enumerate.py:24:1)

Python version: 3.9.20
Transcrypt version: 3.9.4
Web Browser:
Chromium Version 137.0.7151.68 (Official Build) (64-bit),
Firefox 139.04

it is so weird because enumerate() is a primitive function, and almost all Python code would not be able to be executed without it. But, I installed from the standard library:

python3.9 -m pip install transcrypt

I uninstalled Transcrypt, and reinstalled it, but the result was the same.

Was there a new update of Transcrypt recently? If not, I am afraid that something was messed up in my working environment. If you have any idea about how to fix, please leave a comment.

Thanks in advance.
