['c', 2]] >>> with open('example.csv', 'w') as f: ... writer = csv.writer(f) ... writer.writerows(table1) ... >>> # now demonstrate the use of fromcsv() ... table2 = etl.fromcsv('example.csv') >>> table2 +-----+-----+ | foo | bar | +=====+=====+ | 'a' | '1' | +-----+-----+ | 'b' | '2' | +-----+-----+ | 'c' | '2' | +-----+-----+ The `source` argument is the path of the delimited file, all other keyword arguments are passed to :func:`csv.reader`. So, e.g., to override the delimiter from the default CSV dialect, provide the `delimiter` keyword argument. Note that all data values are strings, and any intended numeric values will need to be converted, see also :func:`petl.transform.conversions.convert`. dialectexcel)sourceencodingerrorsheaderN)r setdefaultr rrrrcsvargsrrD/var/www/Datamplify/venv/lib/python3.10/site-packages/petl/io/csv.pyfromcsvs'  rcKs$|ddt|f|||d|S)zw Convenience function, as :func:`petl.io.csv.fromcsv` but with different default dialect (tab delimited). r excel-tab)rrr)rrrrrrfromtsvAs rTcKs2t|}|ddt|f||||d|dS)aE Write the table to a CSV file.
