In the python docs example m = re.search('b(c?)', 'cba'), what does the 1 in n.start(1) means? and why is it 2? Thankyou

@caroltang0331 could you give me the context of this code? It's hard for me to tell what n is. In general, the start(1) would give the starting offset of the first group matched.

I'm sorry I think I meant m instead of n. I have attached the context. The document said it creates a substring matched by group but I'm a bit confused on what it means. Thank you
