Querydict a string

I have the following string:

string = 'amount=2000|captureDay=0|captureMode=AUTHOR_CAPTURE|currencyCode=978|merchantId=002020000000001|orderId=|transactionDateTime=2012-04-12T12:09:56+02:00|transactionReference=1212943|keyVersion=1|authorisationId=0020000006791167|complementaryCode=|maskedPan=|paymentMeanBrand=IDEAL|paymentMeanType=CREDIT_TRANSFER|responseCode=00'

How can i make a querydict out of this.

I want to be able to use item['amount'] which returns 2000

EDIT:

what i've tried so far:

dict = string.split('|')

Output is:

['amount=2000', 'captureDay=0', 'captureMode=AUTHOR_CAPTURE', 'currencyCode=978', 'merchantId=002020000000001', 'orderId=', 'transactionDateTime=2012-04-12T12:09:56+02:00', 'transactionReference=1212943', 'keyVersion=1', 'authorisationId=0020000006791167', 'complementaryCode=', 'maskedPan=', 'paymentMeanBrand=IDEAL', 'paymentMeanType=CREDIT_TRANSFER', 'responseCode=00']

items = dict(item.split('=', 1) for item in string.split('|'))

print items['amount']

The first split (on the pipe symbol) yields a list of strings in "x=y" format. The second split takes each of these and returns a list of two elements. This list of 2-element lists is then fed into the dict() constructor.

You could substitute | with & and give the whole string to Django's QueryDict.

See the QueryDict documenation

E.g. 

In [1]: from django.http import QueryDict

In [2]: sample = 'amount=2000|captureDay=0|captureMode=AUTHOR_CAPTURE|currencyCode=978|merchantId=002020000000001|orderId=|transactionDateTime=2012-04-12T12:09:56+02:00|transactionReference=1212943|keyVersion=1|authorisationId=0020000006791167|complementaryCode=|maskedPan=|paymentMeanBrand=IDEAL|paymentMeanType=CREDIT_TRANSFER|responseCode=00'

In [3]: qdict = QueryDict(sample.replace('|','&'))

In [4]: qdict
Out[4]: <QueryDict: {u'orderId': [u''], u'keyVersion': [u'1'], u'transactionReference': [u'1212943'], u'paymentMeanType': [u'CREDIT_TRANSFER'], u'maskedPan': [u''], u'currencyCode': [u'978'], u'paymentMeanBrand': [u'IDEAL'], u'complementaryCode': [u''], u'amount': [u'2000'], u'authorisationId': [u'0020000006791167'], u'responseCode': [u'00'], u'captureMode': [u'AUTHOR_CAPTURE'], u'captureDay': [u'0'], u'transactionDateTime': [u'2012-04-12T12:09:56 02:00'], u'merchantId': [u'002020000000001']}>

Go for:

>>> {i.split("=")[0]:i.split("=")[1] for i in string.split('|')}
