The `sklearn.preprocessing.Imputer` module in Python's scikit-learn library is used for imputing missing values in a dataset. It provides methods to fill the missing values with either the mean, median, mode, or a constant value, depending on the user's choice. This module is particularly useful in data preprocessing tasks before applying machine learning algorithms, as it helps in handling missing data by replacing them with appropriate values.
