Deepti Chopra is an author in the fields of computing and artificial intelligence, whose book Mastering Natural Language Processing with Python is included in the Chinese book database. Publicly available information about her nationality, dates of birth and death, educational background, and professional career is limited, making it difficult to reconstruct a complete personal biography. Judging from the available work, her writing focuses on natural language processing, using the Python programming language as a tool for readers who wish to apply artificial intelligence methods to practical text-processing tasks. Books of this kind typically combine conceptual explanation with hands-on coding, helping readers understand basic steps such as tokenization, language modeling, and text classification before moving on to more complete applications. For Chinese readers, such translated and introduced works help connect international technical practice with local learning needs, and are suitable for readers with some programming background who wish to enter the field of natural language processing.
