Hello All,
I am trying to match python dictionary value. Here I store value in string type. When any new string is coming its check weather already string available in dictionary, if Yes then it will return string if not it will add the string into dictionary with key- numeric.
Dictionary=
{
"key1": "String",
"Key2": "String2"
}
Is there any best solution available for string matching?
Python dictionary objects have two methods: .keys() and .values() that will list the corresponding values. Very useful. Example:
>>> a = {1 : 'a', 2 : 'b'}
>>> a.keys()
[1, 2]
>>> a.values()
['a', 'b']
You can perform a check on whether a string is already one of the values using the"in" operator:
>>> 'a' in a.values()
True
>>> 'c' in a.values()
False

@Boris L. Glebov is it possible to check dynamic values using object method??
you can do this with a set
sets hold unique values and will allow you to check against them to see if something is already in your dictionary.
example:
>>> string = 'foo bar foo foo bar1 bar2'
>>> dictionary = {}
>>> stringlist = string.split()
>>> stringset = set([])
>>> i = 1
>>> for word in stringlist:
>>> if word not in stringset:
>>> stringset.add(word)
>>> dictionary.update({i:word})
>>> i = i+1
>>> else:
>>> pass
>>> print dictionary
should give you
{1: 'foo', 2: 'bar', 3: 'bar1', 4: 'bar2'}
may not be the most efficient, but it works
