How I can repair this error: ### attempt 4 from sqlalchemy import create_engine user = '*****' pasw = '*****' host = 'TD'

# connect
td_engine = create_engine('teradata://' + user + ':' + pasw + '@' + host + ':22/')

from sqlalchemy import create_engine

engine = create_engine('sqlite:///:memory:', echo=True) user = '****' pasw = '****' host = 'TD'

connect td_engine = create_engine('teradata://' + user + ':' + pasw + '@' + host + ':22/') Traceback (most recent call last):

File "", line 8, in td_engine = create_engine('teradata://' + user + ':' + pasw + '@' + host + ':22/')

This is a lot of code in a format that isn't easy to replicate. Try making a minimal reproducible example. In particular it needs to be minimal: cut out code until the error almost disappears. And replace the use of an excel file with lists directly in the code. – Alex Hall
