Take a loot at pybitcointools, or have a look at this article with the same toppic.

Answer 2

You could do it with BitcoinLib . Import the raw transaction hex as Transaction object and then sign it with the private key.

private = "5c1a005d669f8521036f7c13138830f15b2d6a016facf9c6361362573e41a083"
raw_tx = ""  # Insert your raw tx in Hex format
t = Transaction.import_raw(raw_tx)
t.sign(private)

In this example the private key is in hex format, but bytes, key objects or WIF encoded strings are accepted as well.
