Sequences.
A core concept in Biopython is the biological sequence, and this is represented by the Seq class. A Biopython Seq object is similar to a Python string in many respects: it supports the Python slice notation, can be concatenated with other sequences and is immutable.
Sequence annotation.
The SeqRecord class describes sequences along with information such as name description and features in the form of SeqFeature objects. Each SeqFeature object specifies the type of the feature and its location.

- History:
Began in 1999 and it was first released in July 2000. It was developed during a similar time frame and with analogous goals to other projects that added bioinformatics capabilities to their respective programming languages, including BioPerl, BioRuby and BioJava.
- Design:
Follows the conventions used by the Python programming language to make it easier for users familiar with Python. For example, Seq and SeqRecord objects can be manipulated via slicing, in a manner similar to Python's strings and lists. #DataVisualization

A beginner's guide to interpreting Box plot.

A thread ๐Ÿงต

#pythonkachilla2 #pythonkachilla #pakdatasci #DataScience #MachineLearning #DataVisualization #Statistics
Box plot is also called box and whiskers plot.

It gives us information about different things which help us get insights of the data, these include median (Q2), first quartile (Q1), third quartile (Q3), minimum value, maximum value, outliers, and interquartile range (IQR). Image
1. The line in the middle of the box is the median value.
50% of the data is on one side of the median, and 50% of the data is on the other side of the median.

2. The first quartile (Q1) is the middle value between the median and minimum value in the data set. (See figure)

Numpy is used for numerical computations including matrix calculations and multidimensional array operations. Performing numerical computation in Python is time-consuming so we use NumPy for fast computation.

In Data Science, when you get the data you have to preprocess it to make it suitable for analysis. Pandas library provides us the tools to manipulate the data and make sense of the data. It is used for data cleaning/wrangling
