rapidtables is a module for Python 2/3, which does only one thing: converts lists of dictionaries to pre-formatted tables. And it does the job as fast as possible.

rapidtables is focused on speed and is useful for applications which dynamically refresh data in console. The module code is heavily optimized and written purely in Python.

And unlike other similar modules, rapidtables can output pre-formatted generators of strings or even generators of tuples of strings, which allows you to colorize every single column.

pip install rapidtables

# if you need to keep strict column ordering, use OrderedDict for the rows
data = [
    { 'name': 'John', 'salary': 2000, 'job': 'DevOps' },
    { 'name': 'Jack', 'salary': 2500, 'job': 'Architect' },
    { 'name': 'Diana', 'salary': None, 'job': 'Student' },
    { 'name': 'Ken', 'salary': 1800, 'job': 'Q/A' }
]

from rapidtables import format_table, FORMAT_GENERATOR_COLS
from termcolor import colored

header, rows = format_table(data, fmt=FORMAT_GENERATOR_COLS)
spacer = '  '
print(colored(spacer.join(header), color='blue'))
print(colored('-' * sum([(len(x) + 2) for x in header]), color='grey'))
for r in rows:
    print(colored(r[0], color='white', attrs=['bold']) + spacer, end='')
    print(colored(r[1], color='cyan') + spacer, end='')
    print(colored(r[2], color='yellow'))

Pretty cool, isn't it? Actually, it was the most complex example, you can work with header + table rows already joined:

from rapidtables import format_table, FORMAT_GENERATOR

header, rows = format_table(data, fmt=FORMAT_GENERATOR)
print(colored(header, color='blue'))
print(colored('-' * len(header), color='grey'))
for r in rows:
    print(colored(r, color='yellow'))

Or you can use make_table function to return the table out-of-the-box (or print_table to instantly print it), and print it in raw:

print_table(data)

name  salary  job
----  ------  ---------
John    2000  DevOps
Jack    2500  Architect
Ken     1800  Q/A

Formats a table. Outputs data in raw, generator of strings (one string per row) or generator of tuples of strings (one tuple per row, one string per column):

• fmt=rapidtables.FORMAT_RAW raw string
• fmt=rapidtables.FORMAT_GENERATOR generator of strings
• fmt=rapidtables.FORMAT_GENERATOR_COLS generator of tuples of strings

Align columns:

• align=rapidtables.ALIGN_LEFT align all columns to left
• align=rapidtables.ALIGN_NUMBERS_RIGHT align numbers to right (default)
• align=rapidtables.ALIGN_RIGHT align all columns to right
• align=rapidtables.ALIGN_CENTER align all columns to center
• align=rapidtables.ALIGN_HOMOGENEOUS_NUMBERS_RIGHT align numbers to right but consider the table is homogeneous and check col values only to first number or string (works slightly faster)

To predefine aligns, set align to tuple or list:

align=(rapidtables.ALIGN_LEFT, rapidtables.ALIGN_RIGHT, ....)

number of items in list must match number of columns in table.

You may also customize headers, separators etc. Read pydoc for more info.

Generates a ready to output table. Supports basic formats:

table = rapidtables.make_table(data, tablefmt='raw')

name  salary  job
-----------------------
John     2000  DevOps
Jack     2500  Architect
Diana          Student
Ken      1800  Q/A

table = rapidtables.make_table(data, tablefmt='simple')

name   salary  job
----   ------  ---------
John     2000  DevOps
Jack     2500  Architect
Diana          Student
Ken      1800  Q/A

table = rapidtables.make_table(data, tablefmt='md') # Markdown

| name  | salary | job       |
|-------|--------|-----------|
| John  |   2000 | DevOps    |
| Jack  |   2500 | Architect |
| Diana |        | Student   |
| Ken   |   1800 | Q/A       |

table = rapidtables.make_table(data, tablefmt='rst') # reStructured, simple

=====  ======  =========
name   salary  job
=====  ======  =========
John     2000  DevOps
Jack     2500  Architect
Diana          Student
Ken      1800  Q/A
=====  ======  =========

table = rapidtables.make_table(data, tablefmt='rstgrid') # reStructured, grid

+-------+--------+-----------+
| name  | salary | job       |
+=======+========+===========+
| John  |   2000 | DevOps    |
+-------+--------+-----------+
| Jack  |   2500 | Architect |

| Diana |        | Student   |
+-------+--------+-----------+
| Ken   |   1800 | Q/A       |
+-------+--------+-----------+

The same as make_table, but prints table to stdout.

(Python 3.7)
