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

If name == 'main'

if __name__ == "__main__":

If name == 'main' in python

# if __name__ == '__main__' checks if a file is imported as a module or not.
# example: 
def main():
    print('Hello World')
    
if __name__ == '__main__':
    # This code won't run if this file is imported.
    main()

import math

print("before functionA")

    print("Function A")

print("before functionB")
def functionB():
    print("Function B {}".format(math.sqrt(100)))

print("before __name__ guard")
if __name__ == '__main__':
    functionA()
