Splitting a semicolon-separated string to a dictionary, in Python

"Name1=Value1;Name2=Value2;Name3=Value3"

dict = {
    "Name1": "Value1",
    "Name2": "Value2",
    "Name3": "Value3"
}

s= "Name1=Value1;Name2=Value2;Name3=Value3"
dict(item.split("=") for item in s.split(";"))

>>> s = "Name1='Value=2';Name2=Value2;Name3=Value3"

>>> dict(csv.reader([item], delimiter='=', quotechar="'").next()
         for item in csv.reader([s], delimiter=';', quotechar="'").next())

{'Name2': 'Value2', 'Name3': 'Value3', 'Name1': 'Value1=2'}

>>> import urlparse
>>> urlparse.parse_qs("Name1=Value1;Name2=Value2;Name3=Value3")
{'Name2': ['Value2'], 'Name3': ['Value3'], 'Name1': ['Value1']}
