Comparing different types in python

If someone already have experience with languages like C/C++, Java, C#
comparison between two variables of different types results in a compile error.
But in Python this will simply evaluate to false. So beware when comparing a string and int
containg same values. when we print, they look the same.
I actually faced this issue when I am receving a param from a config file
and comparing with some int value in the program something similar to the following.

	batch_size = cnf.get_batch_size()
	batch = []
	#Some code to fill the batch
	if len(batch) == batch_size:
	#Flush out the batch by saving to DB
	else:
	#Some other code
	#The Fix here is not to forget to convert the config parameter to int
	batch_size = int(cnf.get_batch_size())
	num1 = "3"
	num2 = 3
	print(num1)
	print(num2)
	if num1 == num2:
	print("Equal")
	else:
	print("Not equal")
