Answers for "name == main"

python name = main

if __name__ == "__main__":
  # Code inside of here will only run if the python script was launched directly
  # This code will not run if imported as a module

__name__== __main__ in python

# If the python interpreter is running that module (the source file)
# as the main program, it sets the special __name__ variable to have
# a value “__main__”. If this file is being imported from another 
# module, __name__ will be set to the module’s name.
if __name__=='__main__':
  # do something
