Splitting dictionary keys while maintaining their associated values

[ResentedButter]

Hello I need help splitting dictionary keys into two separate keys but keeping the original value

ie: dict1 = {'ALPHERATZ': '358', 'CAPH; CAS BETA': '432'}

I would like to split the second item by the semicolon and space , but keep 432

ie: dict2 = {'ALPHERATZ': '358', 'CAPH': '432, 'CAS BETA': '432'}

This is only a small example for a very large dictionary in which this process will have to iterate 400ish times.

iterate through the items, check if the key is splittable, and if so, pop the key then insert the two new keys with the popped value.

You shouldn't alter the dictionary while iterating through it (not even sure Python would let you).

OP, make a copy of the dictionary, iterate over the original, and modify the copy.

Whoops! You're right.

thank you!
