I am having a string which is having repeating patterns but not sure how many they are. I want to grep these using regex

For example:

I am having following string

str = "var1 123 var2 234 key sdrfw3 current junk varn adads"
match = re.search("(\w*)\s*(\w*)", str)
print match.group(1), match.group(2)

Problem is I am not sure how many key values will come in this string but all will follow same pattern. How to grep key and value

You may use `re.findall(r'(\w+)\s+(\w+)', s)`. – Wiktor Stribiżew Aug 22 '18 at 07:01
Are the "variables" always named `var + number`? If not, how can you distinguish them from "current junk"? What rules can be used to differentiate "junk" from variables? – Julio Aug 22 '18 at 07:04
Thing is all are space separated. there is no fix pattern for keys and values – Sumit Aug 22 '18 at 07:05
