How to Check if a Number is Odd or Even using Python?
In this article, we will show you how to check if a number is odd or even in python. Below are the methods to accomplish this task − Using modulo (%) operator Using Recursion Using the Binary AND (&) operator Using modulo (%) operator Python's modulo (%) operator (also called the remainder operator) is useful to determine if a number is odd or even. We obtain the remainder of the division of a number by 2. If it is 0, it is even otherwise it is odd Even Number − A number that can be divided by 2, ...
Read MoreHow to Convert Celsius To Fahrenheit using Python?
In this article, we will show you how to convert Celsius To Fahrenheit using Python. Celsius Celsius is a temperature measurement unit that is also known as centigrade. It is an SIderived unit that is used by the majority of countries throughout the world. It is named after the Swedish astronomer Anders Celsius. Fahrenheit Fahrenheit is a temperature scale named after the Polish-born German physicist Daniel Gabriel Fahrenheit, and it uses degrees Fahrenheit as a temperature unit. To obtain Fahrenheit equivalent of celsius, multiply by 1.8 and add 32 - f=c*1.8+32 Or we can use another formula − ...
Read MoreHow can I fill out a Python string with spaces?
A string is a collection of characters that can represent a single word or a whole sentence. Unlike other technologies there is no need to be declared strings in Python explicitly we can define a string with or without the datatype specifier. A string in Python is an object of the String class, which contains multiple methods using which you can manipulate and access strings. In this article we are going to discuss fill out a Python string with spaces. Let’s see various solutions one by one. Using the ljust(), rjust() and center() methods To pad the string with desired ...
Read MoreHow does concatenation operator work on list in Python?
In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. Concatenation of lists is an operation that adds the elements of one list to the end of another. We're discussing list data structures here, therefore we'll join the elements of one list to the end of another. In this article, we will show you how to concatenate lists in python. The following are the different methods to accomplish this task − Using Concatenation(+) Operator Using For Loop(Naive Method) ...
Read MoreHow to convert pandas offset to Python date?
In this article, we convert the pandas offset to date in python. When you subtract the pandas from a date object, you get a pandas Timestamp object. You can convert this object to a String format date or Date object(Standard Python date). Or you can use the timedelta object from the datetime library. Example 1 In the following example code, we remove the offset of 10 days using to_offset(“10D”) from the pandas pd.to_datetime(‘2018-01-04’). from pandas.tseries.frequencies import to_offset import pandas as pd dt = pd.to_datetime('2018-01-04') - to_offset("10D") print(type(dt)) print(dt) Output The output of the above code is as follows. ...
Read MoreHow do we compare Python Dates?
In this article, we will understand how to compare python dates. They are different methods to identify which date is greater or lesser and these methods will be explored in detail. Using the timedelta() method and operator In this method, we use the datetime module and operator to compare two dates. To alter date and time, the datatime module provides timedelta() method. The timedelta() method takes the number of days as an input and returns the date. This method is used to perform arithmetic manipulations. Syntax The syntax of the timedelta() method from the datetime module in python ...
Read MoreThree way partitioning of an array around a given range using Python
Given an array and the range of the array [startval, endval]. Array is divided by three parts. All elements smaller than startval come first. All elements in range startval to endval come next. All elements greater than endval appear in the end. Let’s say we have the following input − A = [1, 14, 51, 12, 4, 2, 54, 20, 87, 98, 3, 1, 32] startval = 14, endval = 54 The output should be − A = [1, 12, 4, 2, 3, 1, 14, 51, 20, 32, 54, 87, 98] Three-way partitioning of an array around ...
Read MorePython Truth Value Testing
What is Truth Value We can use any object to test the truth value. By providing the condition in the if or while statement, the checking can be done. Until a class method __bool__() returns False or __len__() method returns 0, we can consider the truth value of that object is True. The value of a constant is False, when it is False, or None. When a variable contains different values like 0, 0.0, Fraction(0, 1), Decimal(0), 0j, then it signifies the False Value. The empty sequence ‘‘, [], (), {}, set(0), range(0), Truth value of these elements are ...
Read MoreQuine in Python
The Quine is a program, which takes no input, but it produces output. It will show its own source code. Additionally, Quine has some conditions. We cannot open the source code file inside the program. Example 1 Here a simple string formatting is working. We are defining a variable ‘a’, and inside a, we are storing ‘a=%r;print (a%%a)’ Then we are printing the value of a, and also replacing %r with the value of a. Thus the quine is working − a='a=%r;print (a%%a)';print (a%a) Output a='a=%r;print (a%%a)';print (a%a) Example 2 We defined a variable _ and assigned ‘_=%r;print ...
Read MoreTimer objects in Python
In Python, Timer is a subclass of Thread class. Calling the start() method, the timer starts. Timer objects are used to create some actions which are bounded by the time period. Using timer object create some threads that carries out some actions. The Timer is stopped using the cancel() method. How to create a Timer object Following is how you can create a Timer object in Python − threading.Timer(interval, function, args = None, kwargs = None) Starting a Timer The timer.start() is used for start the timer. Here’s an example − Example import threading # All the text displays ...
