Dependecy injection question (Python requests)

I have a Python code for processing requests like this:

class SomeClass:
  def __init__(self):
    #somecodehere
    pass
  
  ...

  def some_method(self, db_data, input):
    #some code
    mixed_item = {**db_data, **input.get('specific_object')} #merge two information
    self.another_method(db_data, input)

  def another_method(info):
    #process info
    pass

obj = SomeClass()
obj.some_method(db_data, request_data)

Regarding dependecy injection, should I change another_method parameters so it receives db_data and input from some_method and leave the merging into info for another_method to handle?
