Thanks for the report. read_parquet
does preserve the numbers as strings, it's just that the in
operator checks for the items in the index rather than the Series data. You can instead use the in
operator on Series.values
to see if an item exists in the Series data, e.g.
"1" in df2.b.values # True
from pandas.
Ah, I see, sorry, I did not realize this was how Series worked.
Closing!
