Introduction to Pandas and Time Series Analysis [PyCon DE]Alexander Hendorf
Most data is allocated to a period or to some point in time. We can gain a lot of insight by analyzing what happened when. The better the quality and accuracy of our data, the better our predictions can become.
Unfortunately the data we have to deal with is often aggregated for example on a monthly basis, but not all months are the same, they may have 28 days, 31 days, have four or five weekends,…. It’s made fit to our calendar that was made fit to deal with the earth surrounding the sun, not to please Data Scientists.
Dealing with periodical data can be a challenge. This talk will show to how you can deal with it with Pandas.
Abstract: This PDSG workshop introduces the basics of Python libraries used in machine learning. Libraries covered are Numpy, Pandas and MathlibPlot.
Level: Fundamental
Requirements: One should have some knowledge of programming and some statistics.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Data Analysis
Data Analysis, also known as analysis of data or data analytics, is a
process of
Inspecting,
Cleansing,
Transforming, and
Modelling data with the goal of discovering useful information,
suggesting conclusions, and supporting decision-making.
3. Python as Data Science Tool?
Easy to learn
Scalability
Growing Data Analytics Libraries
Python community
4. Python Packages for Data Analysis
• Numpy and Scipy – fundamental scientific computing.
• Pandas – data manipulation and analysis.
• Matplotlib – plotting and visualization.
• Scikit-learn– machine learning and data mining.
• StatsModels – statistical modeling, testing, and analysis.
5. NumPY
The NumPy (Numeric Python) package required for high performance
computing and data analysis.
Low level library written in C (and FORTRAN) for high level
mathematical functions.
Overcomes the problem of running slower algorithms on Python by
using multidimensional arrays and functions that operate on arrays.
Allows concise and quick computations by VECTORIZATION.
To use NumPy module, we need to import it using:
6. Python in combination with NumPy,
Scipy and Matplotlib can be used as a
replacement for MATLAB.
Matplotlib module provides MATLAB-
like plotting functionality.
NumPy – A Replacement for MatLab
7. Operations Using NumPy
Fast vectorized array operations for data munging and cleaning, subsetting and
filtering, transformation, and any other kinds of computations
Common array algorithms like sorting, unique, and set operations
Efficient descriptive statistics and aggregating/summarizing data
Data alignment and relational data manipulations for merging and joining
together heterogeneous data sets
Expressing conditional logic as array expressions instead of loops with if-elif-
else branches
Group-wise data manipulations (aggregation, transformation, function
8. Core Python Vs NumPy
"Core Python", means Python without any special modules, i.e. especially without
NumPy.
Advantages of Core Python:
high-level number objects: integers, floating point
containers: lists with cheap insertion and append methods, dictionaries with fast
lookup
Advantages of using NumPy with Python:
array oriented computing
efficiently implemented multi-dimensional arrays
9. Advantages of using NumPy with Python
Array oriented computing
Efficiently implemented multi-dimensional arrays
Designed for scientific computation
Standard mathematical functions for fast operations on entire arrays of data without
having to write loops
Tools for reading / writing array data to disk and working with memory-mapped files
Linear algebra, random number generation, and Fourier transform capabilities.
10. NumPy(Array)
NumPy array is a grid of values.
Similar to lists, except that every element of an array must be the same type.
Alias for NumPy library is np.
np.array() is used to convert a list into a NumPy array.
11. NumPy(Array)
SHAPE
Shape function gives a tuple of array dimensions and can be used to change the
dimensions of an array.
Using shape to get array dimensions
Using shape to change array dimensions
12. NumPy(Array)
RESHAPE
Gives a new shape to an array without changing its data.
Creates a new array and does not modify the original array itself.
15. NumPy(Array)
CONCATENATE
Two or more arrays can be concatenated together using the concatenate function with a
tuple of the arrays to be joined:
If an array has more than one dimension, it is possible to specify the axis along which
multiple arrays are concatenated. By default, it is along the first dimension.
16. NumPy(Array)
ZEROS
The zeros tool returns a new array with a given shape and type filled with 0's.
ONES
The ones tool returns a new array with a given shape and type filled with 1's.
17. NumPy(Array)
IDENTITY
Returns an identity array.
An identity array is a square matrix with all the main diagonal elements as 1 and the rest
as 0 . The default type of elements is float.
18. NumPy(Array)
EYE
Returns a 2-D array with 1's as the diagonal and 0's elsewhere.
The diagonal can be main, upper or lower depending on the optional parameter .
Positive k is for the upper diagonal, a negative k is for the lower, and a 0k (default) is for the
main diagonal.
19. NumPy(Linear Algebra)
The NumPy module also comes with a number of built-in routines for linear algebra
calculations.
These can be found in the sub-module linalg.
Some of the built in routines are:
linalg.det
linalg.eiv
linalg.inv
20. NUMPY(LINEAR ALGEBRA)
linalg.det: Computes the determinant of an array.
linalg.eig: Computes the eigen values and right eigen vectors of a square array.
21. Operations On NumPy
We can perform operations on
numpy such as addition,
subtraction , multiplication and
even dot product of two or more
matrices
22. Operations On NumPy
To transpose a matrix, use
matrix_name.T operation .
To find what shape is of
transposed matrix is use
matrix_name.T.shape to find it.
TRANPOSE
23. Operations On NumPy
We can find the sum of matrices by
sum() operation.
We can find the maximum number in
the matrix by using max() operation.
We can find the position of the
element in the matrix where the
maximum or minimum value is in
place.
We can find the mean of a matrix
using mean() operation.
