URL: https://github.com/apache/tvm/pull/14452
This PR fixes a bug in TVMScript printer handling tuples on the RHS of an
assignment, i.e.:
```python
... = (a, b, c)
^^^^^^^^^
```
The existing sugar removes the brackets surrounding `(a, b, c)`, which
makes it slightly more readable as:
```python
... = a, b, c
```
However, it overlooks a possibility where the tuple could be empty or has
only one element, i.e.
```python
... = (a, ) // Case 1: The tuple has only one element
... = () // Case 2: The tuple is empty
```
In both cases, removing brackets may lead to wrong outcome.
This patch fixes this bug.
