> Apparently there’s not, Python’s API is just a very thin wrapper around
the C implementation, and the C API can only use the current locale. Very bad
but what can you expect from something designed 40 years ago. I guess a context
manager is the best we can do for now—if bad things happen down the road we’ll
add a lock to work around it.
This also works, and that's converting the python datetime format to babel:
```
def ds_format(ds: str, input_format: str, output_format: str, locale: str |
None = None) -> str:
def strftime_to_babel_format(format_str):
# Mapping of strftime format codes to Babel format codes
format_mapping = {
'%a': 'EEE', '%A': 'EEEE', '%w': 'e', '%d': 'dd', '%b': 'MMM',
'%B': 'MMMM', '%m': 'MM',
'%y': 'yy', '%Y': 'yyyy', '%H': 'HH', '%I': 'hh', '%p': 'a',
'%M': 'mm', '%S': 'ss',
'%f': 'SSSSSS', '%z': 'Z', '%Z': 'z', '%j': 'D', '%U': 'w',
'%W': 'w',
'%c': 'EEE MMM dd HH:mm:ss yyyy',
'%x': 'MM/dd/yy', '%X': 'HH:mm:ss', '%%': '%'
}
for k, v in format_mapping.items():
format_str = format_str.replace(k, v)
return format_str
