The following code demonstrates the use of variables in Python regex.The variable cannot contain any special or meta characters or regular expression. We just use string concatenation to create a string.Example import re s = 'I love books' var_name = 'love' result = re.search('(.+)'+var_name+'(.+)',s) print result var_name = 'hate' s2 = 'I hate books' result = re.search('(.+)'+var_name+'(.+)',s2) print resultOutputThis gives the output
It is very easy to do date and time maths in Python using timedelta objects. Whenever you want to add or subtract to a date/time, use a datetime.datetime(), then add or subtract datetime.timedelta() instances. A timedelta object represents a duration, the difference between two dates or times. The timedelta constructor has the following function signature −datetime.timedelta([days[, seconds[, microseconds[, milliseconds[, minutes[, hours[, weeks]]]]]]])Note: All arguments are optional and default to 0. Arguments may be ints, longs, or floats, and may be positive or negative. You can read more about it here − https://docs.python.org/2/library/datetime.html#timedelta-objectsExampleAn example of using the timedelta objects and dates ... Read More
In this article, we will show you how to set the first day of each week to a weekday using Python. Now we see 2 methods to accomplish this task− Using setfirstweekday() function Using setfirstweekday() function to set a given weekday Number Method 1: Using setfirstweekday() function to set given weekDay Algorithm (Steps) Following are the Algorithm/steps to be followed to perform the desired task − Use the import keyword, to import the calendar module. Use the prmonth() function (It is used to print the calendar for a month) of the calendar module to print the calendar ... Read More
In this article, we will show you how to sort a Python date string list. Now we see 3 methods to accomplish this task− Now we see 2 methods to accomplish this task− Using sort() and lambda functions Using sort() function Using sorted function Method 1: Using sort() and lambda functions Algorithm (Steps) Following are the Algorithm/steps to be followed to perform the desired task − Use the import keyword, to import the datetime from datetime module (To work with dates and times, Python has a module called datetime). Create a variable to store the input list ... Read More
There is no standard JSON format for dates. Although JavaScript does have a standard date format that is human readable, sorts correctly, includes fractional seconds(which can help re-establish chronology) and conforms to ISO 8601. You can convert a Python date to the JS date format using the strftime function and deserialize it using the client that needs this date. To get an ISO 8601 date in string format in Python 3, you can simply use the isoformat function. It returns the date in the ISO 8601 format. For example, if you give it the date 31/12/2017, it'll give you the ... Read More
The WebSocket is a protocol which provides a way of creating web applications that supports real-time bi-directional communication between both clients and servers. WebSocket makes it much easier to develop these types of applications. Most modern browsers support WebSocket including Firefox, Internet Explorer, Chrome, Safari, and Opera, and more and more server application frameworks are now supporting WebSocket as well.For a production environment, where multiple WebSocket servers are needed for getting a good performance and high availability of the website or application, a load balancing layer which understands the WebSocket protocol is required, NGINX supports the use of WebSocket from ...

In electronic circuits, we use an electronic device called operational amplifier (Op-Amp). The operational amplifier is a high-gain multistage differential amplifier. It has two inputs and one output, where the input terminals are named as inverting terminal and non-inverting terminal. The inverting terminal of the Op-Amp is marked with positive (+) polarity, whereas the noninverting represents the negative (-) polarity terminal. Depending on the circuit configuration, the operational amplifier is classified into two types namely, Inverting Amplifier Non-Inverting Amplifier This article is meant for explaining the differences between an inverting amplifier and a noninverting amplifier. But before that, ... Read More
