I'm going to make some changes before merging

Looks like a lot of hardcoded filesystem paths and lines that are much longer than 79 characters to me... fix is easy enough: instead of

def encodemacaroons(macaroonfile='/media/important/important/lnd/data/chain/bitcoin/mainnet/admin.macaroon', ...)

just do

MACAROON_FILE='/media/important/important/lnd/data/chain/bitcoin/mainnet/admin.macaroon'
def encode_macaroons(
    macaroonfile=MACAROON_FILE,
    ...
):

It's producing strings but I can't get it to connect to Zap.

I've checked connectivity, and Zap connects to lnd manually when given the files.

The specification is here
https://github.com/LN-Zap/lndconnect/blob/master/lnd_connect_uri.md

Perhaps the base64 encoding is not being adhered to properly?

is the hostname correct? Is the tls certificate valid for that hostname?

Done. Use noma lnd connectstring to get the url to your lnd wallet
