How do I get the scriptPubKey from a bitcoin taproot (segwit v1 / bech32m) address?

I have this function that converts a Bitcoin private key as an integer to a public key and an address.

 def get_seg_v1_from_pkey(imported_key): imported_key_toint = int(imported_key) privKeytoHex = imported_key_toint.to_bytes(32, 'big').hex() prv = HDKey(privKeytoHex) prv_tnet = TNetHDKey(privKeytoHex) pubkey = prv.public_hex pub_tnet = prv_tnet.public_hex version = 0x01 address = program_to_witness(version, pubkey[2:], main=True) address_testnet = pubkeyhash_to_addr_bech32(pubkeyhash=pub_tnet[2:], prefix='tb', witver=1, separator='1', checksum_xor=0x2bc830a3) return pubkey, address, address_testnet 

​

HDKey imports the integer into a proper private key object like what is used in https://github.com/bitcoinops/taproot-workshop. TNetHDKey is a custom function I wrote that does the same thing as HDKey but it stores the private key in a way that makes it easily convertible to a testnet address.

​

I want to get the scriptPubKey from an address like in this function in https://github.com/bitcoinops/taproot-workshop:

 def create_spending_transaction(self, txid, version=1, nSequence=0): """Construct a CTransaction object that spends the first ouput from txid.""" # Construct transaction spending_tx = CTransaction() # Populate the transaction version spending_tx.nVersion = version # Populate the locktime spending_tx.nLockTime = 0 # Populate the transaction inputs outpoint = COutPoint(int(txid, 16), 0) spending_tx_in = CTxIn(outpoint=outpoint, nSequence=nSequence) spending_tx.vin = [spending_tx_in] # Generate new Bitcoin Core wallet address dest_addr = self.nodes[0].getnewaddress(address_type="bech32") scriptpubkey = bytes.fromhex(self.nodes[0].getaddressinfo(dest_addr)['scriptPubKey']) # Complete output which returns 0.5 BTC to Bitcoin Core wallet amount_sat = int(0.5 * 100_000_000) dest_output = CTxOut(nValue=amount_sat, scriptPubKey=scriptpubkey) spending_tx.vout = [dest_output] return spending_tx 

​

Notice these lines in the above function:

 # Generate new Bitcoin Core wallet address dest_addr = self.nodes[0].getnewaddress(address_type="bech32") scriptpubkey = bytes.fromhex(self.nodes[0].getaddressinfo(dest_addr)['scriptPubKey']) 

​

`self.nodes[0]` refers to a running instance of bitcoind on your computer. I want to replicate this function without requiring a running instance of bitcoind. In my version of this function I plan on passing in `dest_addr` because I won't have a bitcoind instance to generate it. Is there a way to get a scriptPubKey from a raw segwit v1 address?
