A error

Rapidstudent

I have a python code which capture website and save content into csv file. It can successfully run in Execute Python Operator and to save a file in my computer. However finally, A error " no rm_main() method is defined" appear.

How can I add any formula to make it disappear? I need to convert the type of my data such as exampleset ? Actually, I don't know it clearly because I am just a beginner. I  don't know why I successfully save a file but a error appear finally........  please help , please simply teach me how to solve it.

Thank you

The python scripting operator uses rm_main() as a _init_ type of function. This is the main function which executes first and maps to other functions you have in your script. You have to include this always in your code as suggested by the scripting operator.

# rm_main is a mandatory function, 
# the number of arguments has to be the number of input ports (can be none),
#     or the number of input ports plus one if "use macros" parameter is set
# if you want to use macros, use this instead and check "use macros" parameter:
#def rm_main(data,macros):
def rm_main(data):
    print('Hello, world!')
    # output can be found in Log View
    print(type(data))

    #your code goes here

    #for example:
    data2 = pandas.DataFrame([3,5,77,8])

    # connect 2 output ports to see the results
    return data, data2
