Python with Pandas and SciPy
Python is a high-level, interpreted programming language that has gained immense popularity in various fields, particularly in data science, machine learning, and scientific computing. Two of the most crucial libraries that enhance Python’s capabilities in these areas are Pandas and SciPy.
History of Python
Python was created by Guido van Rossum and first released in 1991. The language was designed with an emphasis on code readability and simplicity, making it an excellent choice for beginners while also powerful enough for experts. Over the years, Python has evolved significantly, with major versions released, including Python 2 in 2000 and Python 3 in 2008. The transition from Python 2 to Python 3 marked a significant change in the language, with Python 3 focusing on improving the language’s performance and consistency.
Pandas was developed by Wes McKinney in 2008 and has since become the go-to library for data manipulation and analysis in Python. SciPy, which builds on NumPy, was developed in 2001 and provides additional functionality for scientific and technical computing.
