The “if-else” statement executes a block of code based on the specified condition. If the specified condition is true, then the if block will execute

To reverse the list element, the “reverse()” method is used in Python. The “reversed()” function also accepts the list and returns the reversed iterable object.

To sort the elements of a list in ascending or descending order, the “sort()” method and “sorted()” function is used in Python.

The “replace()” method in Python replaces the old substring value with a new substring value. By default, it will replace all the occurrences of a substring.

“while” loop executes the block of code until the condition remains “True”. It iterates infinite times if the increment/decrement value is not defined.

To sort a list of strings, the“sort()” and “sorted()” functions are used in Python. The sorting of data also varies using the key and reverse parameters

In Python, the “math.log10()” function of the “math” module is used to calculate the logarithm of a given positive number to base 10.

In Python, the hexadecimal to decimal conversion is carried out using the inbuilt “int()” function, “literal_eval()”, “while” loop, and “dictionary”.

In Python, an inbuilt “input()” function is used to take the user input value and returns it in the form of a string by default.

To clear all the items of the dictionary, the “dict.clear()” function is used in Python. “del” keyword deletes the dictionary rather than just the items in it.

To convert float to int, the inbuilt functions such as “int()”, “math.floor()”, “math.ceil()”, “round()”, and “math.trunc()” are used in Python.

To convert integers into a string, the inbuilt “str()” function, “.format()” function, “f-string” method and “%s” operator are used in Python.

In Python, an inbuilt “len()” function, the “for loop”, and the “length_hint()” function is used to find the length of the list.

In Python, “string slicing”, “re.sub()”, “replace()”, and “List Data Structure” methods replace characters at a specific position of the string.

In Python, the “for” loop iterates on the range() function and operates on each element. The “range()” function must have a “stop” argument value

To create a new file in python, the open() function is used. It accepts two parameters: the complete path and the “x” character.

The “dict.keys()”, “List Comprehension”, “for loop with append()”, “Unpacking with *” and “itemgetter()“are used to convert dictionary keys to lists.

The “str()” function is used to return any input data type as a string. Data types, such as list, dict, etc., can be converted into a string using this function.

In Python, the index number is used to access the items of a Python tuple. The items of tuples are accessed individually and in the form of ranges.

In Python, the “len()” function, “not” operator, “not with strip()” and “not with isspace()” methods are used to check if the string is empty

In Python, the “len()” function, the “for loop with isinstance() function”, and the recursive function are used to calculate the dictionary’s length.

The “OR” operator in Python “if statement” is used to combine multiple conditions and filter out the information based on the specified conditions.

In Python, the “math.log2()” function of the “math” module returns the logarithm of the number to base 2. The input number must be greater than zero.

In Python, the “rand()”, “randint()”, and “np.empty()” functions create “1-D”, “2-D”, and “3-D” arrays with different random values.

In Python, the “np.dot()” function of the “Numpy” package is used to calculate the dot product of scalar, vectors, 1-D, and 2-D arrays.

In Python, the “cv2.imread()” function is used to read the image from the specified file. The image is displayed using another function, “cv2.imshow()”.

In Python, the “re.findall()” function of the “regex” module returns the non-overlapping pattern of the given string in the form of a list of strings.

Python provides a built-in function named “set.add()” that adds a new element to a set. The set.add() function accepts exactly one argument.

The “math.atan()” function takes a numeric value and returns the inverse tangent of the given number in radians (within the range of “-Pi/2” to “Pi/2”).

The “Fibonacci series” is created using the “for loop” iteration of any user-defined range. The Fibonacci series is generated by adding the previous two numbers.

In Python, the pillow module is used for multiples operation on digital images like cropping, filtering, drawing and enhancing, etc

In Python, the “math.ceil()” function takes positive or negative numeric values as arguments and rounds off the given numbers to the nearest integer.

To get the length of a Python string, a built-in function named “len()” or a user-defined function with “for loop” or “if-else” statements is used.

To create a Python list of dictionaries, place all the dictionaries within the square bracket using the comma-separated syntax

In Python, the “append()” function, “DataFrame.loc” and “pandas.concat()” functions are used to add or insert rows to pandas DataFrame.

The “DataFrame.reset_index()” resets any pandas DataFrame. The index of DataFrame is arranged according to the default index or the user-defined index

The “sort_values()” functions with “default parameter”, “descending order”, and “multiple columns” are used to Sort DataFrame by Column in Pandas

The “json.dumps()” function of the json module converts the value of the dictionary into JSON. The value is stored in “keys” and then converted into JSON.

In Python, the pandas “iterrows()” function iterates over the DataFrame rows and performs user-defined operations on them.
