Example 2: how to define main in python
# Defining main function def main(): print("hello World") # Using the special variable # __name__ if __name__=="__main__": main()
Example 3: __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
Example 4: main function python\
print("Hello") print("__name__ value: ", __name__) def main(): print("python main function") if __name__ == '__main__': main()
Example 5: python main
if __name__ == "__main__": # execute only if run as a script main()
Example 6: main in python
