Ref #14427
The DataFrame constructor had no
strict
parameter, while the Series constructor does. Non-strict construction is useful when the input data is not guaranteed to be clean.In this example, the result is similar to a non-strict cast of the data to the desired data type.
This will also allow handling mixed ints/floats cleanly in the future.
The default behavior is unchanged, as previously DataFrame construction was always strict, corresponding to
strict=True
.
