We are going to explore different methods of calendar module in this tutorial. Let's see one by one.calendar.monthrange(year, month)The method calendar.monthrange(year, month) returns starting weekday number and number of days of the given month. It returns two values in a tuple. Let's see one example.Example Live Demo# importing the calendar module import calendar # initializing year and month year = 2019 month = 1 # getting the tuple of weekday and no. of days weekday, no_of_days = calendar.monthrange(year, month) print(f'Weekday number: {weekday}') print(f'No. of days: {no_of_days}')OutputIf you run the above code, you will get the following results.Weekday number: 1 No. of ...

According to computational complexity theory, the potential method is defined as a method implemented to analyze the amortized time and space complexity of a data structure, a measure of its performance over sequences of operations that eliminates the cost of infrequent but expensive operations.In the potential method, a function Φ is selected that converts states of the data structure to non-negative numbers. If S is treated as state of the data structure, Φ(S) denotes work that has been accounted in the amortized analysis but not yet performed. Thus, Φ(S) may be imagined as calculating the amount of potential energy stored ... Read More
The print and echo are both language constructs to display strings. The echo has a void return type, whereas print has a return value of 1 so it can be used in expressions. The print_r is used to display human-readable information about a variable.ExampleLet us now see an example that displays output using echo, print, and print_r: Live DemoOutputThis will produce the following output−Array... Value = John Value = Jacob Value = Tom Value = Tim Displaying Array Values using print... Value = John Value = Jacob Value = Tom Value = Tim Displaying Array Values using print_r... Array ( [0] => John [1] => Jacob [2] => Tom [3] => Tim )
Function Overloading in PHPFunction overloading is a feature that permits making creating several methods with a similar name that works differently from one another in the type of the input parameters it accepts as arguments.ExampleLet us now see an example to implement function overloading− Live DemoOutputThis will produce the following output−9.42648Function Overriding in PHPIn function overriding, the parent and child classes have the same function name with and number of argumentsExampleLet us now see an example to implement function overriding− Live DemoOutputThis will produce the following output−Base class function! Base class function declared final! Derived class function! Base class function declared final!Read More
The randomized meldable heap(also called as Meldable Priority Queue) supports a number of common operations. These are known as insertion, deletion, and a searching operation, findMin. The insertion and deletion operations are implemented in terms of an additional operation specific to the meldable heap, Meld(A1, A2).MeldThe basic target of the meld (also called as merge) operation is to take two heaps (by taking each heaps root nodes), A1 and A2, and merges them, returning a single heap node as a result. This heap node is the root node of a heap containing all elements from the two subtrees rooted at ... Read More
What is Assembly Tolerance Stack up Analysis?In short, assembly tolerance stacks up analysis is defined as the tolerance value of the whole assembly or a specific gap of the assembly when we are aware about the tolerance values of all its components.Assembly tolerance chain stack up analysis can be accomplished in different ways. The simplest procedure is termed as the worst case method, which we discuss here.Discussion about Worst Case Method of Assembly Tolerance Stack UpLet, we have an assembly of four thick sheets like below −The thickness and tolerance of the four sheets are displayed in the above figure. ...

In this tutorial, we are going to discuss the string method str.casefold(). It doesn't take any arguments. The return value of the method is a string that is suitable for the caseless comparisons.What are caseless comparisons? For example, the german lower case letter ß is equivalent to ss. The str.casefold() method returns the ß as ss. It converts all the letters to lower case.Example Live Demo# initialising the string string = "TUTORIALSPOINT" # printing the casefold() version of the string print(string.casefold())OutputIf run the above program, you will get the following result.tutorialspointLet's see the example where caseless comparison works. If you directly compare ... Read More
Definition and importance of Tolerance AnalysisTolerance analysis is the term given to a number of processes used to calculate the overall variation and effect of variation on products stemming (i.e. arisen) from imperfections in manufactured parts.Tolerance analysis is performed by product design engineers as they prepare to components for manufacturing. This is done to ensure according to end users’ demand as well as guarantee so that all manufactured components are fitted together within an assembly.The Definition of Tolerance AnalysisTolerance analysis is defined as the general term for activities related to the subject of potential collected variation in mechanical parts and assemblies. ...

A global variable can be accessed in any part of the program. However, in order to be modified, a global variable must be explicitly declared to be global in the function in which it is to be modified. This is accomplished, conveniently enough, by placing the keyword GLOBAL in front of the variable that should be recognized as global.ExampleThe code is as follows wherein we can see how to declare a global variable in PHP− Live DemoOutputThis will produce the following output−Value = 2ExampleLet us now see another example− Live DemoOutputThis will produce the following output−5
We have a method called astype(data_type) to change the data type of a numpy array. If we have a numpy array of type float64, then we can change it to int32 by giving the data type to the astype() method of numpy array.We can check the type of numpy array using the dtype class. Let's check the data type of sample numpy array.Example# importing numpy library import numpy as np # creating numpy array array = np.array([1, 2, 3, 4, 5]) # printing the data type of the numpy array print(array.dtype)OutputIf you run the above code, you will get the ...
