Comprehensive tutorial on how to send and the catch SIGTERM signal in Bash and Python to terminate the running process softly using practical examples.
IndexError List Assignment Index Out of Range Solved
When a new value is assigned to an index that does not exist in the list, Python raises the “list assignment index out of range” error.
What is R String in Python?
A “Raw String” provides a convenient way to work with strings containing special characters in Python. It is created by prefixing the string literals with “r”.
Seaborn Violin Plot
In Python, to display the distribution of quantitative data across different levels of one or multiple categorical variables, “seaborn.violin()” method is used.
Python U Before String Meaning
Python “2.x” used the symbol “u” before the string notation in order to handle Unicode strings, but Python “3.x” uses Unicode by default.
Scipy Nquad
The “scipy.integrate.nquad()” function of the “Scipy” library is used to determine the numerical integration of functions of any dimension.
Converting Python String to Date
The “datetime.strptime()” method, the “dateutil” module, or the “pandas.to_datetime()” method is used to convert a Python string to a datetime object.
How to Transpose Matrix Python
The “numpy.transpose()” method, nested “for” loop, nested “List Comprehension”, and “zip()” function is used to transpose the input matrix in Python.
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.
Python Combine Single String into a List of String
Python’s built-in methods, such as the “eval()” method and “ast()” method are used to convert the string into a list of strings.
Python Append to string
The “+=” operator, “join()” method, “f-String” method, “string.format()” method, and “Concatenation Operator +” are used to append one string to another.
Matplotlib Invert Y-Axis
To revert the graph’s y-axis in Python, the “invert_yaxis()” method, “plt.ylim()” method, and the “plt.axis()” method are used.
How to Check If a List Is Empty in Python
The “if/else”, “bool()” and “len()” functions, “not” operators, “NumPy” module, or comparison with an empty list is used to check if a list is empty in Python.
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 “isascii()” method in Python is a pre-built string method that checks whether all the characters in a string are ASCII characters or not.
