Regular expression to match comma separated list of key=value where value can contain commas

Question

I have a naive \"parser\" that simply does something like:
[x.split(\'=\') for x in mystring.split(\',\')]

However mystring can be something like<

Can you try this, it worked for me:

mystring = "foo=bar,breakfast=spam,eggs,e=a"
n = []
i = 0

for x in mystring.split(','):
    if '=' not in x:
        n[i-1] = "{0},{1}".format(n[i-1], x)
    else:
        n.append(x)
        i += 1
print n

You get result like:

  ['foo=bar', 'breakfast=spam,eggs', 'e=a']

Then you can simply go over list and do what you want.
