### Bounds Calculation
7

8
```python { .api }
9
def bounds(ob):
10
    """
11
    Returns a (minx, miny, maxx, maxy) bounding box.
12
    
13
    Parameters:
14
    - ob: dict, feature record or geometry object
15
    
16
    Returns:
17
    tuple: (minx, miny, maxx, maxy) bounding box coordinates
18
    """
19
```
20

21
### Version Information
22

23
```python { .api }
24
def show_versions():
25
    """Display version information for debugging."""
26

27
# Module constants
28
__version__: str          # Fiona version (e.g., "1.10.1")
29
__gdal_version__: str     # GDAL version string
30
gdal_version: tuple       # GDAL version tuple
31
```
32

33
#### Usage Examples
34

35
```python
36
import fiona
37
from fiona import bounds
38

39
# Calculate bounds from geometry
40
point_geom = {'type': 'Point', 'coordinates': [-122.4, 37.8]}
41
point_bounds = bounds(point_geom)
42
print(f"Point bounds: {point_bounds}")
43

44
# Calculate bounds from feature
45
feature = {
46
    'geometry': {'type': 'Point', 'coordinates': [0, 0]},
47
    'properties': {'name': 'Origin'}
48
}
49
feature_bounds = bounds(feature)
50

51
# Get version information
52
print(f"Fiona version: {fiona.__version__}")
53
print(f"GDAL version: {fiona.__gdal_version__}")
54
print(f"GDAL tuple: {fiona.gdal_version}")
55

56
# Show detailed version info for debugging
57
fiona.show_versions()
58
```
