6.9. Price

6.9.1. PriceFloat

class easydata.parsers.price.PriceFloat(*args, currency_hint: Optional[str] = None, decimal_separator: Optional[str] = None, **kwargs)

Bases: easydata.parsers.price.BasePriceFloat

PriceFloat parser will try to extract prices from a str, int or float type values and return them as float type. It supports price extraction from various types.

PriceFloat parser is based upon Text parser and therefore inherits all parameters from it and it’s usage.

To read docs regarding other parameters than the one described here, please go to Text documentation.

Getting Started

Lets import first easydata module.

>>> import easydata as ed

PriceFloat supports any query object for fetching data.

>>> test_dict = {'price': 'Was 99.9€'}
>>> ed.PriceFloat(ed.jp('price')).parse(test_dict)
99.9

Another example with a float data source.

>>> test_dict = {'price': 3330.90}
>>> ed.PriceFloat(ed.jp('price')).parse(test_dict)
3330.9

Parameters

decimals

We can manipulate how many decimals parsed value will be have. By default this limit is 2, but we can change this value with a decimals parameter.

In this example lets set our value output to 3 decimals.

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=3).transform(test_dict)
999.913

Now lets set it to 0 decimals.

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=0).parse(test_dict)
1000

We can completely disable number rounding to decimals by settings

In this example lets set our value output to 3 decimals.

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=3).transform(test_dict)
999.913

Now lets set it to 0 decimals.

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=0).parse(test_dict)
1000

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=3).parse(test_dict)
999.913

Now lets set it to 0 decimals.

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=0).transform(test_dict)
1000

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=3).parse(test_dict)
999.913

Now lets set it to 0 decimals.

>>> test_dict = {'price': '999.91264'}
>>> ed.PriceFloat(ed.jp('price'), decimals=0).parse(test_dict)
1000

We can completely disable number rounding to decimals by settings decimals parameter to None.

>>> test_text = '999.91264'
>>> ed.PriceFloat(decimals=None).transform(test_text)
999.91264

>>> test_text = '999.91264'
>>> ed.PriceFloat(decimals=None).transform(test_text)
999.91264

>>> test_text = '999.91264'
>>> ed.PriceFloat(decimals=None).parse(test_text)
999.91264

Note

Default value of decimals parameter can be defined through a config variable ED_PRICE_DECIMALS in a config file or a model.

6.9.2. PriceInt

class easydata.parsers.price.PriceInt(*args, currency_hint: Optional[str] = None, decimal_separator: Optional[str] = None, **kwargs)

Bases: easydata.parsers.price.PriceFloat

PriceInt works exactly the same as PriceFloat but returns int type instead float.

Getting Started

Lets import first easydata module.

>>> import easydata as ed

PriceInt supports any query object for fetching data.

>>> test_dict = {'price': 'Was 99.9€'}
>>> ed.PriceInt(ed.jp('price')).parse(test_dict)
99

Another example with a float data source.

>>> test_dict = {'price': 3330.90}
>>> ed.PriceInt(ed.jp('price')).parse(test_dict)
3330

6.9.3. PriceText

class easydata.parsers.price.PriceText(*args, currency_hint: Optional[str] = None, decimal_separator: Optional[str] = None, **kwargs)

Bases: easydata.parsers.price.PriceFloat

PriceText works exactly the same as PriceFloat but returns str type instead float.

Getting Started

Lets import easydata module.

>>> import easydata as ed

PriceText supports any query object for fetching data.

>>> test_dict = {'price': 'Was 99.9€'}
>>> ed.PriceText(ed.jp('price')).parse(test_dict)
'99.9'

Another example with decimal limit.

>>> test_dict = {'price': 'Was 3.330,9246'}
>>> ed.PriceText(ed.jp('price'), decimals=3).parse(test_dict)
'3330.925'
