Python - Convert a key-value string to a dictionary

I have a Python script that reads a string from a file which is have several key=value elements. An example is:

A=Astring,B=Bstring,C=Cstring

Is there an easy way to read this straight into a dictionary? Or would I have to manually build a dictionary after splitting by , and again by =.

You can simply split based on , first and then for each item you can split based on =, like this

data = "A=Astring,B=Bstring,C=Cstring"
print dict(i.split("=") for i in data.split(","))
# {'A': 'Astring', 'C': 'Cstring', 'B': 'Bstring'}

Split with a generator expression and the dict() function:

d = dict(entry.split('=') for entry in inputstring.split(','))

Demo:

>>> inputstring = 'A=Astring,B=Bstring,C=Cstring'
>>> dict(entry.split('=') for entry in inputstring.split(','))
{'A': 'Astring', 'C': 'Cstring', 'B': 'Bstring'}
