The indexing is the specific position of the element from the list. The unequal elements of two lists refer to those indexes whose elements are not matched from both lists. In Python, we have some built-in functions like enumerate(), zip(), filter(), etc. that can be used to filter unequal elements of two lists corresponding same index. Let’s take an example of this Given list, lst_1 = [10, 20, 30, 40, 50] lst_2 = [1, 20, 3, 40, 50] Then the final result becomes [20, 40, 50] these elements from the list matches the corresponding same index. Syntax The following syntax ...

The name Numpy stands for Numerical Python. It helps to solve the mathematical operation on an array. In Python, we have some built-in functions such as nditor(), T(), array(), shape[], and apply_along_axis() that will be used to iterate over columns in Numpy. Syntax The following syntax is used in the examples- nditer() The NumPy module contains this built-in function for iterator objects. T() This function refers to transposing of the index in a column dataframe. array() This is a built-in function in Python that creates the array. An array is defined by collecting the items of ...

The reverse slice is defined by creating a slice that begins with the length of the string and ends with the 0th index. For reversing the list element it will use the negative value notation, where we can get a reversed order of the original list element. In Python, we have some built-in functions such as append(), len(), and, range() will be used to solve the K elements Reversed Slice. Syntax The following syntax is used in the examples- append() This built-in method in Python can be used to add the element at the end of the list. len() ...

Python refers to the high-level programming language that has various tools and built-in functions to analyze text data. This problem statement is a common task that uses some built-in functions- filter(), isdigit(), isalpha(), findall(), split(), and, append() to find the both alphabet and numbers using Python. Let’s see how to take the input of the program to get the result: Input my_text = "WELCOME TO CLUB100" Output CLUB100 Syntax The following syntax is used in the examples- filter() The filter() method is applied when it filter the items based on specific conditions. In simple terms, it allows ...

The tuple list defines the two different datatypes of Python that represent the static and dynamic characteristics respectively. In a dictionary, we can create keys using tuples whereas lists cannot be used as keys. In Python, we have some built-in functions like next(), items(), index(), lambda, and, min() will be used to Find the first element by the second in the tuple list. This type of circumstance occurs when the second element holds the important information as a key for identifying the desired tuple. Let’s take an example of this: The given tuple list, my_tup = [("India", 35), ("Indonesia", 12), ...

The dictionary is one of the most popular among four datatypes known for unordered collection of key-value pairs. The Python matrix will be used to represent the list of lists whereas an inner list represents the row-value of a matrix. A coordinate dictionary is defined as tuples to set the rows and columns by giving coordinates value. In Python, we have some built-in functions such as len(), range(), zip(), etc. that can be used to solve Convert Matrix to Coordinate dictionary. Syntax The following syntax is used in the examples- len() The len() is a built-in method in Python ...

The indices are the position of the elements present in the list whereas K defines the specific value to target the smallest element from the list. Sometimes, we are working in the field of web development and database these tasks generally occur to solve this problem statement. In Python, we have built-in functions like sorted(), range(), len(), etc. that will be used to find the indices for k Smallest elements. Syntax The following syntax is used in the examples- sorted() The sorted() is an in-built function in Python that helps to return the new sorted list while ...

The dictionary is one of the famous datatypes of Python that consist of keys with value pairs. The strings list is the set of elements that are represented either in a single or double quotation. In Python, we have some built-in functions such as keys(), set(), intersection, and append() will be used to find the dictionary keys present in strings List. Let’s take an example of this. There are two available sets:- The given dictionary, {'T': 1, 'M': 2, 'E': 3, 'C': 4} The given list, [T, A, B, P, E, L] Therefore, the final result becomes [T, E]. ...

The tuple is a popular datatype of Python that represents the collection of objects or elements separated by commas. The frequency of data type defines the total number of counts of a specific variable type. Python has four primitive variable types: integer, float, boolean, and string. In Python, we have some built-in functions such as type(), isinstance(), filter(), lambda, len(), and list() will be used to Find the frequency of a given Datatype in a Python tuple. Syntax The following syntax is used in the examples- type() The type() is an in-built function in Python that returns the type ...

The stream of strings is a sequential flow of given data where an individual element of the stream represents a string. The stream allows a large process of string data In C++, we have some STL(Standard template library) based functions such as count() and insert() to Check duplicate in a stream of strings. Using Standard Template Library The program uses C++ STL to set the header file unordered representing the unique key element and helps to solve the duplicates in a stream of strings. Syntax The following syntax is used in the examples- static unordered_set unq_string; The ...
