python - How to convert Euro currency string to float number?

Question

I need to convert a string currency string in Continental Europe format into a float number:

Input:

'6.150.593,22 €'

Realize that decimal point is comma, and thousands separators are period characters.

Output:

6150593.22

I'd read these questions, but they only works for US dollar currency and locale:

• How do I convert a currency string to a floating point number in Python?
• python: how to convert currency to decimal?

currency_euros='6.150.593,22 €'
float(currency_euros[:-2])

Traceback (most recent call last):
  File "<pyshell#28>", line 1, in <module>
    float(currency_euros[:-2])
ValueError: could not convert string to float: '6.150.593,22'

Updated: Following the @IrmendeJong answer:

>>> import locale
>>> locale.setlocale(locale.LC_NUMERIC, "es")
'es'
>>> print(locale.currency(6150593.22))
6150593,22 €
>>> money = '6.150.593,22 €'
>>> locale.atof(money)
Traceback (most recent call last):
  File "<pyshell#68>", line 1, in <module>
    locale.atof(money)
  File "C:Python35liblocale.py", line 318, in atof
    return func(delocalize(string))
ValueError: could not convert string to float: '6150593.22 €'

I'm ashtonished that locale.currency() works fine but its reciprocal method locale.atof() doesn't work.

Answer 1

Use locale.atof https://docs.python.org/3/library/locale.html#locale.atof

>>> import locale
>>> locale.setlocale(locale.LC_NUMERIC,"nl")
'nl'
>>> locale.atof("6.150.593,22")
6150593.22
