Using "meta" with "assign"

Dask DataFrame
2

After thinking about it I don’t think my question makes sense- meta is only needed for applies and not all column assignments. So you could do this if you where using an apply inside assign:

df.assign(c=df.apply(
    lambda row: row["a"].astype(str) + row["b"],
    axis=1,
    meta=("c", str),
))
