Python string unformatter.
Simple string pattern matching using f-string-like syntax.
This module cannot do anything more than re but is much easier to use.
pip install -U unformatUnformatting returns a list-like object.
from unformat import compile, unformat
unformat("{name}_{idx}.csv", "data_001.csv") # Values(name='data', idx='001')
unformat("{name}_{idx:int}.csv", "data_001.csv") # Values(name='data', idx=1)
unformat("{name}_{idx}.csv", "data001.csv") # Error!
name, idx = unformat("{name}_{idx}.csv", "data_001.csv") # `Values` is list-like
# object oriented
ptn = compile("{name}_{idx}.csv")
ptn.unformat("data_001.csv") # Values(name='data', idx='001')Model-based unformatting is also supported.
from unformat import UnformatModel
class Version(UnformatModel):
pattern = "{major}.{minor}.{micro}" # not a field
major: int
minor: int

version = Version.from_string("0.2.1") # Version(major=0, minor=2, micro=1)
