Hi,
I’m Confused. pls, Clarify on this
I clearly understood the concept of above statement, but I don’t know where the situation which I can use that __name__ statement effectively. What I have understood on the statement is python interpreter has some variables by default like that it also have a variable called __name__. During the execution of python files it will assign values to that variable. If it is an stand-alone program execution then the value of __name__ would be “__main__” if python is imported then the value of __name__ would be the file name of the python file.
Example:
#Filename: foo1.py
print “Value of __name__ Variable: ”+__name__
if I execute the above file.
Execution: python foo1.py
Output is:
Value of __name__ Variable: __main__
Whereas if I execute the file as module by importing (i.e.)
#Filename: foo2.py
import foo1
print “I am foo2”
Execution: python foo2.py
Output:
I am foo2
Now, my question is, if(__name__ ==”__main__”): statement used only to identify whether it is main program or stand-alone program. Isn’t it? Am I correct? Pls clarify more……
