Lambda Function, often known as an 'Anonymous Function,' is the same as a normal Python function except that it can be defined without a name. The def keyword is used to define normal functions, while the lambda
The pandas API leverages these strengths of Python, providing robust capabilities for data manipulation and analysis. Functions such as str methods for string operations and support for custom lambda functions enable users to write expressive algorithms directly within their workflows. Python’s compatibil...
