Don't worry. Not everyone knows it...

In this article, I’ll show you how can you create a basic chat bot which utilizes the data provided by you. Here we will be using GPT-Index, OpenAI and Pytho n. Let’s get started by installing the required Python module. Install modules/packages We need to install, two packages named gpt_index and langchain and this can be done using below lines: pip install gpt_index pip install langchain Importing packages Next, we need to import those packages so that we can use them: from gpt_index import SimpleDirectoryReader , GPTListIndex , GPTSimpleVectorIndex , LLMPredictor , PromptHelper from langchain import OpenAI import sys import os Please note that, here, we don’t need an GPU because we are not doing anything local. All we are doing is using OpenAI server. Grab OpenAI Key To grab the OpenAI key, you need to go to https://openai.com/, login and then grab the keys using highlighted way: Once you got the key, set that inside an environment variable(I’m using Windows). If you do not

Can you imagine a life of a programmer using an editor having no intellisense support? In today’s era where most of us are working in many programming languages at the same time, it is very difficult to remember the syntax of all the programming languages? The one thing which is most important is the underlying concept of any programming language and if you are good in those fundamentals, there are various ways to get help in writing code. It could be by using a search engine, by going through some book, by lending fellow coder’s hand, by using editor’s or IDEs capabilities, etc. My personal favorite way is by taking the help of IDE. I prefer the IDE which provides very good support for syntax and coding guidelines. In today’s article, I’m focusing on Jupyter notebook inside VS Code, which is a very common IDE these days when you are coding in Python . By default, syntax support or say intellisense support is not enabled in Jupyter Notebook in VS Code and hence we need to enable it us

Using conditionals or say IF-ELSE statement is quite common when developing any application and based on the programming language, the syntax to handle such conditionals varies but the underline concept remains the same. In this article, I’ll show you how to write an IF statement in Python to check if a given item is present in the collection or not. Have a look at the traditional way to achieve the same: fruits = [‘apple’,’orange’,’banana’,’mango’] fruit = ‘mango’ if (fruit==’apple’ or fruit==’orange’ or fruit==’banana’ or fruit==’mango’): print (‘Found the fruit’) In the above snippet, we have a collection holding multiple fruits and a variable holding one fruit. The idea here is to check whether the given fruit exists in the collection or not.  There is no problem with the above code but we do have a way to optimize it and by optimizing the code, we can achieve the below benefits: less number of lines of code less error prone no need to change code, if more items are added

Python is nowadays a very common language to use, especially when you want to automate something. Hence, we will go with Python to automate our today’s flow wherein we will generate a pivot table using Python and then we will save it back to Microsoft Excel. Input Data I’m considering CSV file as an input, which holds multiple columns as shown in the below sample: Scenario Let’s consider a scenario, wherein we want to generate a pivot table which depicts the interest of students based on the residence. For example, say you want to know how many students are falling under Uncertain category from Rural, then pivot table should be able to provide us with this data. Generating Pivot Table The very first thing we need to do is to grab the CSV data and bring it into the memory, so that we can perform operations on it. Yes, you guessed it right. We can go for a pandas data frame. Once data is available in a data frame, we can filter out the required columns and start our pivoting process.  He

Whenever we think about automating something, there are many questions which come to our mind. Like, How will we schedule it? How many times we want to execute it? Is it possible to automate this scheduling part? Well, in this article I’m going to walk you through all those various steps which are required to schedule a Python script on Windows. Step 1: Prepare The Python script Automation begins with the piece of code which will automate something. So, the first step here is to get ready with a Python script which must be in working condition. There is no constraint on how big or small a script has to be, but we need to make sure that the script is doing what it is intended to do. Step 2: Create An Executable Once the script is verified, we need to create an executable or EXE file as this executable file we are going to schedule in our next step. In order to create an executable in Python, we need to install a package named pyinstaller using pip: pip install pyinstaller Once the packa

In this article, I’ll show you those two lines of Python code, using which you can print calendar of any year. Required Package The pre-requisite to generate calendar is to import the required package named calendar as shown below: from calendar import * Generate Calendar Now to generate a calendar, we need to call constructor and pass in four parameters as shown below: print(calendar(2018,2,1,4)) Here, 2018 is the year for which calendar will be printed 2 signifies width of each character 1 signifies number of lines per week 4 signifies column separation value You can adjust the last three parameters for better spacing in between the text. Output This is how the calendar looks like: I hope you enjoyed generating a calendar of your choice. Make sure to check out my recording explaining each and every parameter discussed in this article:

It is quite common to sort a Python dictionary based on key. But what if you want to perform sorting on the value? In this article, I’m going to show you multiple ways to sort dictionary value and then return the resultant dictionary. Method 1: Using operator The very first method to sort dictionary value is by using sorted(…) function along with operator. So, let’s go ahead and do it as shown below: import operator students = {‘Shweta’:25,’Andy’:30,’Maddy’:3} students = sorted(students.items(), key=operator.itemgetter(1)) print (students) Method 2: Using lambda The second method to sort dictionary value is by using sorted(…) function along with lambda and the code looks as shown below: : import operator students = {‘Shweta’:25,’Andy’:30,’Maddy’:3} students = sorted(students.items(), key=lambda stud:stud[1]) print (students) Output On execution of above two methods, you will get exactly same output. I hope you enjoyed sorting your dictionary values in Python. If you have reached t
