This method does not exclude missing values.
#HOW TO FILTER ROWS IN TRANSCAD SERIES#
The unique methods find the unique values in a series and return the unique values as an Array. df1=df.drop_duplicates(subset=,keep="first")df1
The subset parameter accepts a list of column names as string values in which we can check for duplicates. Len(df.drop_duplicates()) Output 290 SUBSET PARAMTER NOTE :- This method looks for the duplicates rows on all the columns of a DataFrame and drops them.
This method is pretty similar to the previous method, however this method can be on a DataFrame rather than on a single series. What this parameter is going to do is to mark the first two apples as duplicates and the last one as non-duplicate.
ARGUMENT-"LAST"īy default, this method is going to mark the first occurrence of the value as non-duplicate, we can change this behavior by passing the argument keep = last. df.shapeįrom the output above there are 310 rows with 79 duplicates which are extracted by using the. Now to extract the duplicates out (remember the first occurrence is not a duplicate rather the subsequence occurrence are duplicates and will be outputted by this method) we need to pass this method to a data frame. Name: Employee_Name, dtype: object Example df.duplicated().head(3) Output 0 False Confused? Let me try to explain one more time with an example, suppose there are 3 apples in a basket what this method does is mark the first apple as non-duplicate and the rest of the two apples as duplicates. This method does not mark a row as duplicate if it exists more than once, rather it marks each subsequent row after the first row as duplicate. The way duplicated() works by default is by keep parameter, This parameter is going to mark the very first occurrence of each value as a non-duplicate.
