rapidtables 0.0.4

Format/create and print tables from lists of dicts

rapidtables

rapidtables is a module for Python 2/3, which does only one thing: converts lists of dictionaries to pre-formatted ascii 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, it uses only tuples inside and on a relatively small tables (<2000 records) it renders them even faster than Pandas.

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

Example

from rapidtables import format_table
from termcolor import colored

header, cols = format_table(data, fmt=2) # data is list of dicts
spacer = '  '
print(colored(spacer.join(header), color='blue'))
print(colored('-' * sum([(len(x) + 2) for x in header]), color='grey'))
for c in cols:
    print(colored(c[0], color='white', attrs=['bold']) + spacer, end='')
    print(colored(c[1], color='cyan') + spacer, end='')
    print(colored(c[2], color='yellow'))

Pretty cool, isn't it? Actually, it was the most complex example, you can make just

header, rows = format_table(data, fmt=1)

and obtain header + table rows already joined. 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

Quick API reference

format_table

Formats a table. Outputs data in raw, tuple of strings or tuple of tuples of strings, customize headers, separators etc. fmt=0 - raw, 1 - tuple of strings, 2 - tuple of tuples of strings. Read pydoc for more info.

make_table

Generates a ready to output table. Support basic formats:

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

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

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

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

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

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

table = rapidtables.make_table(table, tablefmt='md') # reStructured Text

print_table

The same as make_table, but prints table to stdout.

Benchmarks

rapidtables is written purely in Python, it will loose to Pandas on a large (3000+ records) tables, but on small it works super fast.

Enjoy!
