Remove Special Characters From String Python
To remove special characters from a string the “regular expressions”, “looping”, “join(), and filter()” methods, and the “replace()” method are used in Python.
Python Compile() Function
The “compile()” function in Python is a built-in function that is utilized to compile Python code into “bytecode” by accepting several parameters.
Matplotlib Pie Chart
To create a pie chart in Python, the “matplotlib” library’s “pie()” function can be used along with the multiple required parameters.
NumPy Inverse
The “numpy.linalg.inv()” function of the “numpy.linalg” module is utilized to compute the inverse of the given nonsingular matrix.
Python Next() Function
The Python “next()” function iterates over an iterable object and returns the next item from the iterable and stops with the exception when no items are left.
Python Sorted Reverse
The “sorted()” function is used to sort the strings, lists, tuples, etc. in ascending or descending order or based on single or multiple “key” parameter values.
Python Remove all Instances From List
The “List Comprehension”, the “filter()” function, and the “list.remove()” method is used to remove all instances from the Python list.
Python Finds the String in the File and Print
The “built-in file” operations, “regular expressions”, “read()” and “readlines()” methods are used to find a string in a file and print it in Python.
Python string comparison
To compare strings in Python, various methods such as the “Comparison Operators” or the “is” and “is not” operators are used.
Matplotlib Vertical Line
To create single or multiple vertical lines and spans on your plots various methods such as “axvline()”, “vlines()”, and “ax.axvspan()” are used in Python.
Pandas to records
The Pandas “to_records()” method converts a DataFrame to a NumPy record array, which can be exported to other applications.
List Files in a Directory Python
To list files in a directory in Python, apply the “os.listdir()”, “glob.glob()”, “os.walk()”, “scandir()” functions or the “pathlib.Path.glob()” method.
Python Dictionaries
Python “dictionaries” are a flexible data structure used in a broad range of applications and can be created via “curly braces {}” or “dict()” function.
Cumulative Percentage Pandas
The “cumsum()” and “sum()” functions of the “pandas” library are implemented in Python to find the cumulative percentages.
NumPy Gradient Method
To calculate the gradient of the function or Numpy “N-Dimensional” array the “numpy.gradient()” method is utilized in Python.
Pandas Rolling Groupby
The “pandas” offers multiple useful functions/methods for performing complex calculations on data and the “rolling()” function is one of them.
Python Reverse String
“String Slicing”, “reversed()” function, “for” loop, “join()” method, or “List Comprehension” can be used to reverse the string in Python.
Python Math Trunc
The “math.trunc()” method of the “math” module in Python is used to truncate the fractional or decimal part of the given floating-point number.
Python Pop Last Element from List
The “pop()” method, “slicing” method or the “del” statement is used in Python to remove/pop the last element or specific element from the given list.
