There's a dataframe X with "Year", "Month" and "Day" as integer below,
Year Month Day A B C ...0 2020 10 10 ...1 2021 1 1 ...2 2022 1 10 ...3 2023 10 1 ......
There's another dataframe Y with "Date" as string to be transformed from X, while other columns keep intact. The format is expected to be "YYYY-MM-DD".
Date A B C ...0 2020-10-10 ...1 2021-01-01 ...2 2022-01-10 ...3 2023-10-01 ......
What's the Pandasonic way to make it through, ideally in 1liner ?
