Examples

Load a CSV table

Sample Code:

import pytablereader as ptr
import pytablewriter as ptw


# prepare data ---
file_path = "sample_data.csv"
csv_text = "\n".join([
    '"attr_a","attr_b","attr_c"',
    '1,4,"a"',
    '2,2.1,"bb"',
    '3,120.9,"ccc"',
])

with open(file_path, "w") as f:
    f.write(csv_text)

# load from a csv file ---
loader = ptr.CsvTableFileLoader(file_path)
for table_data in loader.load():
    print("\n".join([
        "load from file",
        "==============",
        "{:s}".format(ptw.dumps_tabledata(table_data)),
    ]))

# load from a csv text ---
loader = ptr.CsvTableTextLoader(csv_text)
for table_data in loader.load():
    print("\n".join([
        "load from text",
        "==============",
        "{:s}".format(ptw.dumps_tabledata(table_data)),
    ]))

Output:

load from file
==============
.. table:: sample_data

    ======  ======  ======
    attr_a  attr_b  attr_c
    ======  ======  ======
         1     4.0  a
         2     2.1  bb
         3   120.9  ccc
    ======  ======  ======

load from text
==============
.. table:: csv2

    ======  ======  ======
    attr_a  attr_b  attr_c
    ======  ======  ======
         1     4.0  a
         2     2.1  bb
         3   120.9  ccc
    ======  ======  ======

Get loaded table data as pandas.DataFrame instance

Sample Code:

import pytablereader as ptr

loader = ptr.CsvTableTextLoader(
    "\n".join([
        "a,b",
        "1,2",
        "3.3,4.4",
    ]))
for table_data in loader.load():
    print(table_data.as_dataframe())

Output:

     a    b
0    1    2
1  3.3  4.4
