how to automatically indent a python code why instrumenting a code ..?

I am reverse engineering a python application. Through which i will be observing the behavior by dynamically instrumenting code inside the application. The problem is i need to insert the code at the correct level of indentation.

For example lets consider a fragment of code i will be instrumenting:

class A:
     def move(self,name):
         name=self.name
         print name
     def move1(self):
         print 'dude'

Now for the above sample code i will be instrumenting entry and exit logging and the instrumented code should look like this below

enter code class A:
     def move(self,name):
         print 'Entry move class='A''
         name=self.name
         print name
         Print'Exit move class='A''
     def move1(self):
         print 'Entry move1 class='A''
         print 'dude'
         print 'Exit move class='A''

This what i need when instrument the code instead i get the following:

enter code class A:
     def move(self,name):
print 'Entry move class='A''
             name=self.name
             print name
print'Exit move class='A''
         def move1(self):
print 'Entry move1 class='A''
             print 'dude'
print'Exit move1 class='A''

Because i am writing a script it insert into the next line and doesnt know the indentation format for a python code.

Is there anyway i could automatically adjust the indentation while inserting or i should need to know the index of the character in the next line and insert spaces to the string and then insert.
