simple way to lock and unlock in python

Question

The file may be simultaneously read and written by Python. Is there a simpler way instead of using lock?

class datamanager:
  def __init__(self, filename = 'filelock'):
    ....

  def write(self, data, isInit = False):
    ....

  def read(self):
    ....

Answer 1

Have a look at this .

Also, the lock is needed only in the write method, as the read method doesn't modify the file.
