I should have been more clear
class first():
print("from first")
def second():
print("from second")
first()
When I run the above code the output is
"from first"
(2ND CODE)
class first():
print("from first")
def second():
print("from second")
first.second()
When I run this code the output is
"from first"
"from second"
Thus going by the above logic
class first():
print("from first")
def second():
print("from second")
first()
first.second()
This should have given the following output
from first
from first
from second
That is I should have got from first 2 times. But instead I got this output.
from first
from second
Why is this so?
