Whether nargs is supported

[Anthony-Dong]

import argparse

if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='Test Cli')
    parser.add_argument('--file', '-f', dest='files', nargs='+', type=str, required=False)
    args = parser.parse_args()
    print(args)

In python, nagrs is convenient for dealing with array types, but with pflag we need to define flag repeatedly
