This course delves into advanced data structures in Python, focusing on the powerful capabilities of the NumPy and Pandas libraries. It introduces the ndarray, a multidimensional array object provided by NumPy, enabling efficient storage and manipulation of large datasets. Additionally, learners will explore the Series and DataFrame structures offered by Pandas, which facilitate data analysis and manipulation in a more user-friendly manner. Throughout the course, students will engage in practical exercises and case studies to reinforce their understanding of how these advanced data structures can be applied in real-world scenarios.
This module introduces the ndarray, the core data structure of the NumPy library that allows for efficient manipulation of large, multi-dimensional arrays. It begins with an overview of what an ndarray is and compares its capabilities to Python's built-in list data structure. The module then covers how to create ndarray objects, access and manipulate both 1D and 2D arrays, and perform various operations on these arrays. By the end of this module, learners will gain a solid understanding of how to effectively use ndarray for numerical and data analysis tasks.

This module introduces the DataFrame data structure in Pandas, which is a two-dimensional labeled data structure that can hold heterogeneous data types. The module begins by defining what a DataFrame is and its significance in data analysis and manipulation. Learners will explore various methods to create DataFrames from sources such as dictionaries, lists, and external files (e.g., CSV). The module covers how to access data within a DataFrame using labels and indices, manipulate rows and columns, and perform operations such as merging and concatenating multiple DataFrames. By the end of this module, students will be proficient in utilizing DataFrames for data manipulation tasks.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
