Duplicate lines are identical or near-identical text entries that appear more than once in a dataset. These can occur due to data entry errors, system glitches, multiple submissions, or merging datasets from different sources. Identifying and removing duplicates is crucial for maintaining data quality and integrity.
Case sensitivity determines whether "Apple" and "apple" are considered the same entry. Case-sensitive processing treats them as different, while case-insensitive processing recognizes them as duplicates. The choice depends on your specific use case and data requirements.
Data cleaning is the process of identifying and correcting errors, inconsistencies, and inaccuracies in datasets. Removing duplicate lines is a fundamental step in data cleaning that improves data quality, reduces storage requirements, and enhances analysis accuracy.
