What kind of argument deserialize_script() requires?

[morfin]

I assume this function expects the input's sig. script, so according to this:
https://bitcoin.org/en/developer-reference#raw-transaction-format

Which part of the script is ? starting from 49? or just the actual sig.script?

| 49 ....................................... Bytes in sig. script: 73
| | 48 ..................................... Push 72 bytes as data
| | | 30450221008949f0cb400094ad2b5eb3
| | | 99d59d01c14d73d8fe6e96df1a7150de
| | | b388ab8935022079656090d7f6bac4c9
| | | a94e0aad311a4268e082a725f8aeae05
| | | 73fb12ff866a5f01 ..................... Secp256k1 signature

deserialize_script("494830450221008949f0cb400094ad2b5eb399d59d01c14d73d8fe6e96df1a7150deb388ab8935022079656090d7f6bac4c9a94e0aad311a4268e082a725f8aeae0573fb12ff866a5f01") or just

deserialize_script("30450221008949f0cb400094ad2b5eb399d59d01c14d73d8fe6e96df1a7150deb388ab8935022079656090d7f6bac4c9a94e0aad311a4268e082a725f8aeae0573fb12ff866a5f01")
And how the return value is broken down? what data structure should I expect from this function?

I'm expecting 4 parts:

• The signature
• SIGHASH_ALL
• Size of public key
• Public Key

Is this the right function to get this data, or am I pointing to the wrong direction?
Thanks.
