What is the pandas python library

The world of the Python libraries

Two-day advanced Python course to provide an overview of important Python libraries.
Can be carried out as company training.

introduction

Python is one of the most popular programming languages ‚Äč‚Äčamong beginners and advanced programmers today. There are many reasons for this.

An important reason here is certainly the extensive standard library, which provides powerful functionalities for everyday programming, such as comfortable character string operations, magic about regular expressions or the possibility of times and periods of time represent and convert. Sure, Python offers such great modules! But who takes the time to get a systematic overview here? We! As part of the course.

In order to equip Python programs with a graphical user interface (GUI), the course also provides an introduction to the powerful and very popular Qt library.

The three libraries Pandas, NumPy and Matplotlib have blossomed into the most important libraries alongside the standard libraries in the processing of numerical data (e.g. numerical data in the form of tables) as a team of three. On the second day of this course, we will therefore take a closer look at these libraries, starting with an introduction to the respective library, showing how data can be read in, represented and processed using NumPy and pandas, and how to use Matplotlib beautifully Ne can generate visualizations of the data / views of the data.

The course content is conveyed directly using clear, small examples that the course participants enter themselves in the form of so-called `` Jupyter Notebbooks ''. The course participants are activated for both days and all content was typed in immediately.

Course objectives

After completing this course, participants will have a solid knowledge of the most important libraries for Python. With this knowledge, the participants can then solve specific problems in Python in their everyday work much faster. The time invested in the basics will therefore pay off for you in the medium term.

Course content

Day 1:

Introduction to important standard libraries
  • Helpful string operations from the string module
  • Mastering regular expressions with the re module
  • Represent times and spans with datetime
  • Calculate statistics with the statistic module
  • Perform directory operations with the os.path module
Graphical user interfaces with Qt
  • Introduction to Qt
  • Surface programming with Python & Qt

Day 2:

Pandas, NumPy, Matplotlib
  • Introduction to the basic data structures of pandas: Series and DataFrame
  • Important operations on Series and DataFrames
  • Introduction to the representation of numerical data using NumPy
  • Create and parameterize visualizations with Matplotlib
  • Work on a specific case study from kaggle.com with Pandas, NumPy and Matplotlib

target group

The target group for this course is anyone who either already knows a little Python or has at least some previous programming experience in a procedural or script programming language and who would like a systematic introduction to the world of Python libraries.

The course is therefore also suitable for programming beginners with little previous programming experience and you do not have to master Python beforehand. Python can also be learned through `` learning by doing '' as part of the course.
