• Seaborn Kdeplot() Method

  The “kdeplot()” method in Python is used to create “KDE” plots that show the distribution of continuous variables in one or more dimensions.

• Python Find Last Occurrence in String

  To find the last occurrence in the string the “rfind()” method, “rindex()” method, “str.rpartition()” method, and “for” loop are used in Python.

• Seaborn Legend

  A legend is automatically added to seaborn graphs by default. However, to add it manually, “plt.legend()” function of “matplotlib” library is used in Python.

• SciPy Bessel Functions

  Learn how to apply two different techniques to solve the SciPy Bessel Functions, a type of second-order differential equation, with some sample problems.

• SciPy Signal Processing

  “scipy.signal” module of “scipy” library provides various functions in Python used to apply different operations on the signal i.e., convolution of two arrays.

• SciPy Odeint

  In Python, the “odeint()” function of the “scipy.integrate” module is utilized to solve a system of ordinary differential equations by integrating them.

• Python Multiline String

  To create a multiline string various methods such as “using triple quotes”, “using escape characters” and “using the join()” are used in Python.

• Python String isascii() Method

  The "string.isascii()" method in Python checks whether a string contains an "ASCII" (American Standard Code for Information Interchange) character or not.

• Python String rindex() Method

  In Python, the “string.rindex()” method is utilized to determine the last occurrence of a particular character in a given string.

• Use of Matplotlib Tight_Layout in Python

  The “tight_layout()” function of the “matplotlib.pyplot” module is utilized to adjust the spacing and padding of the plots.

• Python Replace Characters in a String

  To replace characters or strings in the string the “string.replace()” method, “re.sub()” method, “String Slicing” technique, or “for“ Loop is used in Python.

• Python switch statement syntax

  The series of “if-else” statements, the “Dictionary” and a newly introduced method “match-case” is used to implement the “Switch Statement” in Python.

• Ord function in Python

  The built-in “ord()” function in Python is employed to convert a specific character into its corresponding Unicode code.

• The Python AttributeError

  The “AttributeError” is caused due to various reasons such as “misspelled attribute name”, “incorrect namespace or scope” and “incorrect object type”, etc.

• Python Count Unique Values in the List

  To count unique values in the Python list the “set()” function, the “collections” module, the “for” loop, and the “Numpy” library are used in Python.

• Matplotlib Spectrogram

  Python's “Matplotlib” library provides the “matplotlib.pyplot.specgram()” function that is used to draw a spectrogram in Python.

• Python List -1 Index

  In Python, the “-1” special list index shows the usage of negative indexing, which means the last object of the specified list.
