Try this… It uses the pending filter to find the hash. . It is the ETH_HASH we needed to check…
This script will create a TX and then find it in the Pending TX’s list.

IT will print the following and as you can see thet blockHash , blockNumber and transactionIndex are returning None
blockHash : None
blockNumber : None
from : 0xF88b361E05a504D9ef34FFeE0E6A5137eba219ca
gas : 25000
gasPrice : 1000000000

input : 0x
nonce : 3405
r : 0x11c3bf4a05d04d49ebd8c4a804aedb15301395f72faba631c3d4e096fcaadddc

timestamp : 0x0
to : 0xfAFfb33B924C33381dee35D445013D3200249572
transactionIndex : None
v : 3333200036
value : 1
Waiting a little longer and we can query the Hash as normal
t = '0x6092b0291ef99ba28d7a039f2e0ef48dbf2244c656c510057a870ea2e8d70f02'
hash_info = w3.eth.getTransaction(t)
found = dict(hash_info)
for k, v in found.items():
try:
print(f'{k} : {v.hex()}')
except AttributeError:
print(f'{k} : {v}')
And we see the None fields are completed with Data now that the Transaction has gone through.

I hope this helps…
