Calling a class function inside of __init__

Question

I\'m writing some code that takes a filename, opens the file, and parses out some data. I\'d like to do this in a class. The following code works:

class MyCl         


        

Answer 1

You must declare parse_file like this; def parse_file(self). The "self" parameter is a hidden parameter in most languages, but not in python. You must add it to the definition of all that methods that belong to a class. Then you can call the function from any method inside the class using self.parse_file

your final program is going to look like this:

class MyClass():
  def __init__(self, filename):
      self.filename = filename 

      self.stat1 = None
      self.stat2 = None
      self.stat3 = None
      self.stat4 = None
      self.stat5 = None
      self.parse_file()

  def parse_file(self):
      #do some parsing
      self.stat1 = result_from_parse1
      self.stat2 = result_from_parse2
      self.stat3 = result_from_parse3
      self.stat4 = result_from_parse4
      self.stat5 = result_from_parse5
