fix: remove stray debug print in RangeQueryParameter constructor (#17973)

fixedbydev · parthea · web-flow · commit fe7bfd03bedf · 2026-08-04T15:35:20.000Z
`RangeQueryParameter.__init__` in `google-cloud-bigquery` has a leftover
debug `print()`:

```python
self.range_element_type = self._parse_range_element_type(range_element_type)
print(self.range_element_type.type_._type)   # &lt;- this
self.start = start
```

It fires on every construction, so anyone building a RANGE query
parameter gets the element type dumped to stdout. Easy to reproduce:

```python
&gt;&gt;&gt; from google.cloud.bigquery.query import RangeQueryParameter
&gt;&gt;&gt; RangeQueryParameter(range_element_type="DATE", start="2016-08-11")
DATE
```

This removes the line and adds a small regression test that asserts
nothing is printed during construction. Verified the test fails on the
current code (`Expected 'print' to not have been called. Called 1 times.
Calls: [call('DATE')]`) and passes after the removal. All existing
RangeQueryParameter tests still pass, black is clean.
