YamlTableWriter class can write a YAML format table to the stream from a data matrix.

Sample Code:

Write a YAML table

import pytablewriter as ptw

def main():
    writer = ptw.YamlTableWriter()
    writer.table_name = "example_table"
    writer.headers = ["int", "float", "str", "bool", "mix", "time"]
    writer.value_matrix = [
        [0,   0.1,      "hoge", True,   0,      "2017-01-01 03:04:05+0900"],
        [2,   "-2.23",  "foo",  False,  None,   "2017-12-23 45:01:23+0900"],
        [3,   0,        "bar",  "true",  "inf", "2017-03-03 33:44:55+0900"],
        [-10, -9.9,     "",     "FALSE", "nan", "2017-01-01 00:00:00+0900"],
    ]

    writer.write_table()

if __name__ == "__main__":
    main()

Output:

example_table:
- bool: true
  float: 0.1
  int: 0
  mix: 0
  str: hoge
  time: 2017-01-01 03:04:05+0900
- bool: false
  float: -2.23
  int: 2
  mix: ''
  str: foo
  time: 2017-12-23 45:01:23+0900
- bool: true
  float: 0
  int: 3
  mix: .inf
  str: bar
  time: 2017-03-03 33:44:55+0900
- bool: false
  float: -9.9
  int: -10
  mix: .nan
  str: ''
