Question

I am trying to remove all the \r\n from the python dictionary. What is the easiest way to do so. My dictionary is looking like this at the moment –

 {'': '34.8\r\n', 
  'Mozzarella di Giovanni\r\n': '34.8\r\n', 
   'Queso Cabrales\r\n': '14\r\n', 
   'Singaporean Hokkien Fried Mee\r\n': '9.8\r\n'
}

EDIT : Here’s what I’m trying –

for key, values in productDictionary.items() :
    key.strip()
    values.strip()
    key.strip('"\"r')
    key.strip('\\n')
    values.strip('\\r\\n')
print productDictionary

And the output is still the same.

Answer 1

you can use str.strip():

str.strip() when used with no arguments, strips all types of leading and trailing whitespaces.

>>> productDictionary={'': '34.8\r\n', 
  'Mozzarella di Giovanni\r\n': '34.8\r\n', 
   'Queso Cabrales\r\n': '14\r\n', 
   'Singaporean Hokkien Fried Mee\r\n': '9.8\r\n'
}

>>> productDictionary=dict(map(str.strip,x) for x in productDictionary.items()) 
>>> print productDictionary
>>>
{'': '34.8',
 'Mozzarella di Giovanni': '34.8',
 'Queso Cabrales': '14',
 'Singaporean Hokkien Fried Mee': '9.8'}

help() on str.strip()

S.strip([chars]) -> string or unicode

Return a copy of the string S with leading and trailing whitespace
removed. If chars is given and not None, remove characters in chars
instead. If chars is unicode, S will be converted to unicode before
stripping
