>>> from pcmdi_metrics.utils import replace_date_pattern

>>> replace_date_pattern("pr_mon_GPCP-2-3_PCMDI_gn_197901-201907.nc", "DATE_RANGE")
'pr_mon_GPCP-2-3_PCMDI_gn_DATE_RANGE.nc'

Notes

This function assumes that there’s only one occurrence of the ‘YYYYMM-YYYYMM’ pattern in the filename. If multiple occurrences are possible, consider using re.sub() instead of re.subn().
