I want to insert vacation and holiday dates to my pandas dataframe but can't figure out how... Something doesn't work out with the dates of my dataframe and the dates from the ferien-api and the holidays library. Here is my code:

For Hedera NFTs, if a user wants to have the ability to clawback an NFT (wipe and mint a new one) are you able to perform that operation on a Serial Number basis or is it only at the Token ID level?

E.g. if User A owns two NFTs of the same token ID can you only wipe all tokens or can you specify NFT X?

For Hedera File Service (HFS), I read that the file size limit is 1MB but each transaction is only limited to 6Kb.

The documentation says that we can use FileAppend to add the additional contents so - Does this mean that if I do want to upload a 1MB file, I’d have to do it in increments of 6Kb size transactions?

Right now I'm getting a TRANSACTION_OVERSIZE error

Does the Hedera Hashgraph Network support smart contracts, and is it possible to migrate smart contracts to Hedera?

One public key usually corresponds to one or a specific number of addresses in other cryptocurrencies based on some algorithm.

Is there an API whose params are a public key and who returns all the account Ids corresponding to the public key?

I've got a node server setup which accepts pdf uploads and uploads them to a hedera blockchain testnet.

I have a dataset that i wish to align and make a tree with. I have a data frame with two columns, species and nucleotides. Where species level hasn't been found it is filled with the next available taxonomic level up (i.e. genus, family, order, etc.). This, however, means that there is a single name representing multiple species and sequences. There is also replicated species level rows. I would like to put a number (or something to make it a unique name) after the replicated genus/family/order name and to remove the duplicated species names.

I have a dataset with oppurtunistic species-observations per square kilometer per year (ranging from 1900 to 2019).

There are 139 different sites (square kilomters) in my dataset. I want to make a dataset where for each species for every year for every site, its presence or absence is stated with 1 or 0.

I think this is the appropriate format for including the length of the species-list per year per site in a GLM, to try and account for repeated visits to sites within years (See Szabo et al. 2010 sci-hub.tw/10.1890/09-0877.1 for application of this method).

Data now looks like:
