How to detect whether a Python variable is a function?
In this article, we will learn how to detect whether a Python variable is a function. Sometimes, it is essential to figure out whether or not a Python variable is a function. When the code is a thousand lines long and you are not the creator of the code, this may appear to be of little value, and you may find yourself questioning if a variable is a function or not. Methods Used The following are the methods to check whether a python variable is a function − Using the built-in callable() function Using the isfunction() of the ...
Read MoreHow to create a dictionary of sets in Python?
In this article, we will learn how to create a dictionary of sets in Python. Methods Used The following are the various methods used to accomplish this task − Using the Naive Method Using defaultdict() Method Using setdefault() Method Method 1: Using the Naive Method In this method, we create a dictionary of sets by passing sets as values to the keys. Syntax { ‘Key’: Set 1, ‘Key’:Set 2, ………….., ’Key’: Set n} Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − Create a variable to store the dictionary containing ...
Read MoreHow to Align Text Strings using Python?
In this article, we will learn how to align text strings using Python. We will be using f-strings for this aligning text strings in python. Python's Text Alignment feature is helpful for printing output that is well and cleanly formatted. Sometimes the length of the data to be printed varies, making it appear untidy when printed. By specifying the alignment as left, right, or center and the space (width) to reserve for the string, the output string can be aligned using String Alignment. The text will be formatted using the f-strings. The output string's alignment is defined by the symbols ...
Read MoreFind the maximum element of each row in a matrix using Python
In this article, we will learn a python program to find the maximum element of each row in a matrix. Assume we have taken an NxN input matrix. We will now find the maximum element of each row in an input matrix using the below methods. Methos Used The following are the various methods to accomplish this task − Using Nested For Loops Using max() function Using map(), lambda functions Method 1: Using Nested For Loops Algorithm (Steps) Following are the Algorithm/steps to be followed to perform the desired task. − Create a function maximumRowElement() to print ...
Read MoreFind the least frequent element in an array using Python
In this article, we will learn the python program for getting the least frequent element in an array. Methods Used The following are the various methods to accomplish this task − Using sort() function(Naive Approach) Using Hashing Using Counter() Function Method 1: Using sort() function(Naive Approach) Running two loops is a simple fix. The outer loop selects each element one by one. The inner loop calculates the frequency of the selected element and compares it to the least value reached thus far. This solution's time complexity is O(n^2) Sorting is a better solution. The array is sorted first, ...
Read MoreDecoding and encoding hexadecimal digitals using Python
In this article, we will learn how to decode and encode hexadecimal digits using python. Methods Used Using binascii module Using the base64 module Method 1: Using Binascii Module There are several methods to convert between binary and different ASCII-encoded binary representations in the binascii module. Use the binascii module if all you need to do is encode or decode a raw string of hex digits. Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − Use the import keyword to import the binascii module. Create a variable to store the ...
Read MoreDecimal Equivalents of 1/2, 1/3, . . . ,1/10 in Python
In this article, we will learn a python program that prints out the decimal equivalents of 1/2, 1/3, 1/4, . . . ,1/10. Methods Used The following are the various methods to accomplish this task − Printing Decimal Equivalent of 1/2 Using the range() function Using the decimal module Method 1: Printing Decimal Equivalent of 1/2 We can easily use this code to find the decimal equivalents of 1/2. In this code, we just display the output after storing the result of 1/2 in a variable, inputNumber. Example The following program returns the decimal equivalents of 1/2 − ...
Read MoreCheck if the matrix is lower triangular using Python
In this article, we will learn a python program to check if a matrix is lower triangular. Assume we have taken an input matrix. We will now check whether the input matrix is lower triangular using the below methods. Methos Used The following are the various methods to accomplish this task − Using nested for loop What is a Lower Triangular Matrix? If all the entries above the main/principal diagonal are zero, a square matrix is said to be lower triangular. Example 1 0 0 0 2 3 0 0 1 3 7 0 0 ...
Read MoreCalculating profit or loss using Python
In this article, we will learn a Python Program to calculate Profit Or Loss. The following are the different methods to accomplish this task − Using If Conditional Statements Using the abs() function. What are the selling price, cost price, and Profit and Loss? The price a consumer pays to purchase a product or a commodity is known as the selling price. It is a price that is higher than the cost price and also includes a portion of the profit. Cost price is the cost at which the seller buys the product or the commodity. He ...
Read MoreBreaking a Set into a list of sets using Python
In this article, we will learn how to break a Set into a list of sets in Python. Assume we have taken an input set. We will now break this input set into a list of sets element-wise using the below-mentioned methods. Methods Used The following are the various methods used to accomplish this task − Using For Loop and append(), add() functions Using Python map() & lambda functions Using List Comprehension Method 1: Using For Loop and append(), add() Functions Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − Create ...
