4.4.3. Using pandas DataFrame as tabular data source

You can use pandas.DataFrame as a data source to write a table.

Sample Code:
Write a markdown table from a pandas DataFrame
from textwrap import dedent
import pandas as pd
import pytablewriter
import six

csv_data = six.StringIO(dedent("""\
    "i","f","c","if","ifc","bool","inf","nan","mix_num","time"
    1,1.10,"aa",1.0,"1",True,Infinity,NaN,1,"2017-01-01 00:00:00+09:00"
    2,2.20,"bbb",2.2,"2.2",False,Infinity,NaN,Infinity,"2017-01-02 03:04:05+09:00"
    3,3.33,"cccc",-3.0,"ccc",True,Infinity,NaN,NaN,"2017-01-01 00:00:00+09:00"
    """))
df = pd.read_csv(csv_data, sep=',')

writer = pytablewriter.MarkdownTableWriter()
writer.from_dataframe(df)
writer.write_table()
Output:
| i | f  | c  | if |ifc|bool |  inf   |nan|mix_num |          time           |
|--:|---:|----|---:|---|-----|--------|---|-------:|-------------------------|
|  1|1.10|aa  | 1.0|  1|True |Infinity|NaN|       1|2017-01-01 00:00:00+09:00|
|  2|2.20|bbb | 2.2|2.2|False|Infinity|NaN|Infinity|2017-01-02 03:04:05+09:00|
|  3|3.33|cccc|-3.0|ccc|True |Infinity|NaN|     NaN|2017-01-01 00:00:00+09:00|
