传递参数python脚本

Question

I am trying to know haw can I pass these files as arguments in a py file, and construct dataframe from these files

pd.read_csv('C:/Users/Demonstrator/Downloads/file1.csv',delimiter=';', parse_dates=[0], infer_datetime_format = True)
df_energy2=pd.read_csv('C:/Users/Demonstrator/Downloads/file2.csv', delimiter=';', parse_dates=[0], infer_datetime_format = True)

Passing arguments is simple. You can have a look at https://docs.python.org/3/library/argparse.html

The most easiest way to pass argument to a python script is by adding these line to you python script and modifying them as per need:

if __name__ == '__main__':
    import sys
    if len(sys.argv) != 2 # here I am expecting only one commandline agrument
        print("USAGE: <Scriptname> <commandlineargument>")

        sys.exit(1)
    commandlineValue = sys.argv[1] # sys.argv[0] contains the file name you are running
    # Do what ever you want to do with the commandlineValue, it will just print it
    print ("CommandlineValue Passed is : {}".format(commandlineValue))
