For loop target is not in the namespace
Original
for i in range(10):
pass
print(i)Converted
[[None for i in range(10)], print(i)]Error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'i' is not defined. Did you mean: 'id'?
Support the convertion of `try-except`
As well as raise, finally and with.
Unfortunately, I haven't had any idea to implement this yet.

Support the convertion of `from-import`
Support convertions of `global` and `nonlocal`
Use globals()["var"] to simulate the behavior of global
- #31
- Support nonlocal
