solid principles

single responsibility principle
this violate single responsibility
from pathlib import Path
from zipfile import ZipFile
class FileManager:
  def __init__(self, filename):
    self.path = Path(filename)
 def read(self, encoding="utf-8"):
    return self.path.read_text(encoding)
 def write(self, data, encoding="utf-8"):
   self.path.write_text(data, encoding)
 def compress(self):
   with ZipFile(self.path.with_suffix(".zip"), mode="w") as archive:
   archive.write(self.path)
 def decompress(self):
   with ZipFile(self.path.with_suffix(".zip"), mode="r") as archive
   archive.extractall()

To achieve single responsibility 

from pathlib import Path
from zipfile import ZipFile
class FileManager:
 def __init__(self, filename):
 self.path = Path(filename)
 def read(self, encoding="utf-8"):
  return self.path.read_text(encoding)
 def write(self, data, encoding="utf-8"):
  self.path.write_text(data, encoding)
class ZipFileManager:
 def __init__(self, filename):
  self.path = Path(filename)
 def compress(self):
  with ZipFile(self.path.with_suffix(".zip"), mode="w") as archive:
  archive.write(self.path)
 def decompress(self):
  with ZipFile(self.path.with_suffix(".zip"), mode="r") as archive:
  archive.extractall()
