Study Notes
Libraries in Python
- Libraries are collections of pre-written code that can be reused in various programs, facilitating software development.
- They allow programmers to leverage functionalities developed by others, enhancing productivity and efficiency.
Purpose of the datetime Library
- The datetime library provides classes for manipulating dates and times, making it easier to work with temporal data.
- Key functionalities include creating, formatting, parsing, and performing arithmetic on date and time objects.
Third-Party Libraries
- Third-party libraries are external libraries created by the community or independent developers, not included in the standard Python library.
- These libraries can be installed via package managers like pip and expand Python's capabilities, often covering specialized areas such as data analysis, web development, or machine learning.
Library Types
- Common library types include standard libraries, third-party libraries, and custom libraries.
- Custom libraries are developed by users for specific applications and are tailored to meet particular needs.
'Someone Else Did the Hard Work'
- This phrase emphasizes the advantage of using libraries, as they encapsulate complex code and algorithms that save developers time and effort.
- By utilizing libraries, programmers can build upon established solutions rather than starting from scratch, leading to faster development cycles.
