4.3.1. Configure Output Stream

Reference: stream.

Sample Code
Change output stream of a writer object
import io
import pytablewriter as ptw

def main():
    writer = ptw.MarkdownTableWriter()
    writer.table_name = "zone"
    writer.headers = ["zone_id", "country_code", "zone_name"]
    writer.value_matrix = [
        ["1", "AD", "Europe/Andorra"],
        ["2", "AE", "Asia/Dubai"],
        ["3", "AF", "Asia/Kabul"],
        ["4", "AG", "America/Antigua"],
        ["5", "AI", "America/Anguilla"],
    ]

    # writer instance writes a table to stdout by default
    writer.write_table()

    # change the stream to a string buffer to get the output as a string
    # you can also get tabular text by using dumps method
    writer.stream = io.StringIO()
    writer.write_table()
    print(writer.stream.getvalue())

    # change the output stream to a file
    with open("sample.md", "w") as f:
        writer.stream = f
        writer.write_table()

if __name__ == "__main__":
    main()
