Question
Consider the following statements- Statement A : To “flatten” the dataframe, you can use the reset_index(). Statement B : Use the nunique() to get counts of unique values on a Pandas Series. Both statements are correct Both statements are false A is correct, B is false B is correct, A is false
Solution
Both statements are correct.
Statement A is correct because the reset_index() function in pandas is used to generate a new DataFrame or Series with the index reset. This is useful when the index needs to be treated as a column, or when the index is meaningless and needs to be reset to the default before another operation.
Statement B is also correct because the nunique() function in pandas is used to get a count of unique values. This can be very useful in understanding the distribution of values in a Series.
