how to check transaction signature for buy or sell swap ?

Hi looking at this signature 4rWMeMx4UB8pbqnazhM4aVaueNzPbh33aPYVi6cJxEvvmpw9oK8ZJNn3g1NFbNf58mithnWvmaNpoKviygrDLh6m

is there a way to use solana rpc or websocket to check if this is a buy swap (swapped sol for token mint) or sell (swapped token mint for sol) ?

what should i look for if one would want a python code to parse and print this is a buy swap transaction and this is the bought mint token with the amount of the bought token .

vs
