# ODPS Python SDK and data analysis framework

[![PyPI version](https://img.shields.io/pypi/v/pyodps.svg?style=flat-square)](https://pypi.python.org/pypi/pyodps) [![Docs](https://img.shields.io/badge/docs-latest-brightgreen.svg?style=flat-square)](http://pyodps.readthedocs.org/) [![License](https://img.shields.io/pypi/l/pyodps.svg?style=flat-square)](https://github.com/aliyun/aliyun-odps-python-sdk/blob/master/License) ![Implementation](https://img.shields.io/pypi/implementation/pyodps.svg?style=flat-square)






-----------------

Elegent way to access ODPS API. [Documentation](http://pyodps.readthedocs.org/)

## Installation

The quick way:

```
pip install pyodps[full]
```

If you don't need to use Jupyter, just type

```
pip install pyodps
```

The dependencies will be installed automatically.

Or from source code (not recommended for production use):

```shell
$ virtualenv pyodps_env
$ source pyodps_env/bin/activate
$ pip install git+https://github.com/aliyun/aliyun-odps-python-sdk.git
```

## Dependencies

* Python (>=2.7), including Python 3+, pypy, Python 3.7 recommended
* setuptools (>=3.0)

## Run Tests

- install pytest
- copy conf/test.conf.template to odps/tests/test.conf, and fill it with your account
- run `pytest odps`

## Usage

```python
>>> import os
>>> from odps import ODPS
>>> # Make sure environment variable ALIBABA_CLOUD_ACCESS_KEY_ID already set to Access Key ID of user
>>> # while environment variable ALIBABA_CLOUD_ACCESS_KEY_SECRET set to Access Key Secret of user.
>>> # Not recommended to hardcode Access Key ID or Access Key Secret in your code.
>>> o = ODPS(
>>> os.getenv('ALIBABA_CLOUD_ACCESS_KEY_ID'),
>>> os.getenv('ALIBABA_CLOUD_ACCESS_KEY_SECRET'),
>>> project='**your-project**',
>>> endpoint='**your-endpoint**',
>>> )
>>> dual = o.get_table('dual')
>>> dual.name
'dual'
>>> dual.table_schema
odps.Schema {
c_int_a bigint
c_int_b bigint
c_double_a double
c_double_b double
c_string_a string
c_string_b string
c_bool_a boolean
c_bool_b boolean
c_datetime_a datetime
c_datetime_b datetime
}
>>> dual.creation_time
datetime.datetime(2014, 6, 6, 13, 28, 24)
>>> dual.is_virtual_view
False
>>> dual.size
448
>>> dual.table_schema.columns
[,

]
```

## DataFrame API

```python
>>> from odps.df import DataFrame
>>> df = DataFrame(o.get_table('pyodps_iris'))
>>> df.dtypes
odps.Schema {
sepallength float64
sepalwidth float64
petallength float64
petalwidth float64
name string
}
>>> df.head(5)
|==========================================| 1 / 1 (100.00%) 0s
sepallength sepalwidth petallength petalwidth name
0 5.1 3.5 1.4 0.2 Iris-setosa
1 4.9 3.0 1.4 0.2 Iris-setosa
2 4.7 3.2 1.3 0.2 Iris-setosa
3 4.6 3.1 1.5 0.2 Iris-setosa
4 5.0 3.6 1.4 0.2 Iris-setosa
>>> df[df.sepalwidth > 3]['name', 'sepalwidth'].head(5)
|==========================================| 1 / 1 (100.00%) 12s
name sepalwidth
0 Iris-setosa 3.5
1 Iris-setosa 3.2
2 Iris-setosa 3.1
3 Iris-setosa 3.6
4 Iris-setosa 3.9
```

## Command-line and IPython enhancement

```
In [1]: %load_ext odps

In [2]: %enter
Out[2]:

In [3]: %sql select * from pyodps_iris limit 5
|==========================================| 1 / 1 (100.00%) 2s
Out[3]:
sepallength sepalwidth petallength petalwidth name
0 5.1 3.5 1.4 0.2 Iris-setosa
1 4.9 3.0 1.4 0.2 Iris-setosa
2 4.7 3.2 1.3 0.2 Iris-setosa
3 4.6 3.1 1.5 0.2 Iris-setosa
4 5.0 3.6 1.4 0.2 Iris-setosa
```

## Python UDF Debugging Tool

```python
#file: plus.py
from odps.udf import annotate

@annotate('bigint,bigint->bigint')
class Plus(object):
def evaluate(self, a, b):
return a + b
```

```
$ cat plus.input
1,1
3,2
$ pyou plus.Plus < plus.input
2
5
```

## Contributing

For a development install, clone the repository and then install from source:

```
git clone https://github.com/aliyun/aliyun-odps-python-sdk.git
cd pyodps
pip install -r requirements.txt -e .
```

If you need to modify the frontend code, you need to install [nodejs/npm](https://www.npmjs.com/). To build and
install your frontend code, use

```
python setup.py build_js
