is a small library for extracting price and currency from raw text strings.


  • robust price amount and currency symbol extraction
  • zero-effort handling of thousand and decimal separators

The main use case is parsing prices extracted from web pages. For example, you can write a CSS/XPath selector which targets an element with a price, and then use this library for cleaning it up, instead of writing custom site-specific regex or Python code.

License is BSD 3-clause.



pip install price-parser

price-parser requires Python 3.6+.


Basic usage

from priceparser import Price price = Price.fromstring("22,90 €") price Price(amount=Decimal('22.90'), currency='€') price.amount # numeric price amount Decimal('22.90') price.currency # currency symbol, as appears in the string '€' price.amounttext # price amount, as appears in the string '22,90' price.amount_float # price amount as float, not Decimal 22.9

If you prefer,

has an alias
, they do the same:

from priceparser import parseprice parse_price("22,90 €") Price(amount=Decimal('22.90'), currency='€')

The library has extensive tests (900+ real-world examples of price strings). Some of the supported cases are described below.

Supported cases

Unclean price strings with various currencies are supported; thousand separators and decimal separators are handled:

Price.fromstring("Price: $119.00") Price(amount=Decimal('119.00'), currency='$')

Price.fromstring("15 130 Р") Price(amount=Decimal('15130'), currency='Р')

Price.fromstring("151,200 تومان") Price(amount=Decimal('151200'), currency='تومان')

Price.fromstring("Rp 1.550.000") Price(amount=Decimal('1550000'), currency='Rp')

Price.fromstring("Běžná cena 75 990,00 Kč") Price(amount=Decimal('75990.00'), currency='Kč')

Euro sign is used as a decimal separator in a wild:

Price.fromstring("1,235€ 99") Price(amount=Decimal('1235.99'), currency='€')

Price.fromstring("99 € 95 €") Price(amount=Decimal('99'), currency='€')

Price.fromstring("35€ 999") Price(amount=Decimal('35'), currency='€')

Some special cases are handled:

Price.fromstring("Free") Price(amount=Decimal('0'), currency=None)

When price or currency can't be extracted, corresponding attribute values are set to None:

Price.fromstring("") Price(amount=None, currency=None)

Price.fromstring("Foo") Price(amount=None, currency=None)

Price.fromstring("50% OFF") Price(amount=None, currency=None)

Price.fromstring("50") Price(amount=Decimal('50'), currency=None)

Price.fromstring("R$") Price(amount=None, currency='R$')

Currency hints

argument allows to pass a text string which may (or may not) contain currency information. This feature is most useful for automated price extraction.

Price.fromstring("34.99", currency_hint="руб. (шт)") Price(amount=Decimal('34.99'), currency='руб.')

Note that currency mentioned in the main price string may be preferred over currency specified in

argument; it depends on currency symbols found there. If you know the correct currency, you can set it directly:

price = Price.fromstring("1 000") price.currency = 'EUR' price Price(amount=Decimal('1000'), currency='EUR')

Decimal separator

If you know which symbol is used as a decimal separator in the input string, pass that symbol in the

argument to prevent price-parser from guessing the wrong decimal separator symbol.

Price.fromstring("Price: $140.600", decimal_separator=".") Price(amount=Decimal('140.600'), currency='$')

Price.fromstring("Price: $140.600", decimal_separator=",") Price(amount=Decimal('140600'), currency='$')
