# rapidtables

**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.

## Install

```shell
pip install rapidtables
```

## Example

```python
# 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:

```python
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:

```python
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, 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.

### make_table

Generates a ready to output table. Supports basic formats:

```python
table = rapidtables.make_table(data, tablefmt='raw')
```
```
name  salary  job
-----------------------
John     2000  DevOps
Jack     2500  Architect
Diana          Student
Ken      1800  Q/A
```

```python
table = rapidtables.make_table(data, tablefmt='simple')
```
```
name   salary  job
----   ------  ---------
John     2000  DevOps
Jack     2500  Architect
Diana          Student
Ken      1800  Q/A
``` 

```python
table = rapidtables.make_table(data, tablefmt='md') # Markdown
```
```
| name  | salary | job       |
|-------|--------|-----------|
| John  |   2000 | DevOps    |
| Jack  |   2500 | Architect |
| Diana |        | Student   |
| Ken   |   1800 | Q/A       |
```

```python
table = rapidtables.make_table(data, tablefmt='rst') # reStructured, simple
```
```
=====  ======  =========
name   salary  job
=====  ======  =========
John     2000  DevOps
Jack     2500  Architect
Diana          Student
Ken      1800  Q/A
=====  ======  =========
```

```python
table = rapidtables.make_table(data, tablefmt='rstgrid') # reStructured, grid
```
```
+-------+--------+-----------+
| name  | salary | job       |
+=======+========+===========+
| John  |   2000 | DevOps    |
+-------+--------+-----------+
| Jack  |   2500 | Architect |
+-------+--------+-----------+
| Diana |        | Student   |
+-------+--------+-----------+
| Ken   |   1800 | Q/A       |
+-------+--------+-----------+
```

### print_table

The same as *make_table*, but prints table to stdout.
