Introduction: As businesses increasingly move towards cloud-based solutions, Azure has emerged as a prominent choice for hosting various services and applications. Python, one of the most popular programming languages, offers a plethora of libraries and tools to interact with Azure services. However, before accessing Azure resources programmatically, it’s crucial to understand the authentication mechanisms provided by Azure Active Directory (Azure AD). In this article, we’ll explore different methods to authenticate Azure services using Python. 1. Understanding Azure Authentication: Azure Auth ..read more

a. Concat String with ‘+’ Operator In Python concatenating strings are easy. For example, let’s say you have two strings to merge then you put the plus (‘+’) operator to merge two strings. str1 = "Hello" str2 = "World" str = str1 + ' ' + str2 print(str) The output will be “Hello World“. If you have more strings then just add more operators to merge the strings. b. Concat string with Join function Another way to merge the string is by using the Join() function of the string. For example, str1 = "Hello" str2 = "Python" str3 = "World" str = ' '.join([str1,str2,str3]) print(str) The output ..read more

create a dictionary in Python A dictionary in Python is a key-value pair of objects. Key-value pairs can be different data types. To create an empty dictionary, below is the syntax. dict_example = {} Let’s create a dictionary with some data. car_models = { "Creta": 2024, "Venue" : 2023, "Nexon":2022 } Print this dictionary. Let’s check the datatype of the dictionary. print("\nCheck Datatype") print(type(car_models)) Data type ‘dict’ as you see refers to the class dictionary. To print the specific value. print(f"Creta Model : {car_models['Creta']}") print(f"Venue Model : {car ..read more

Error: response from daemon: Bad response from Docker engine When you run docker commands you may have encountered the error “ERROR: Error response from daemon: Bad response from Docker engine” sometimes on Windows and Linux OS when running the docker desktop. For example, Workaround Check if the docker desktop is running. If the docker desktop is running, check if the docker desktop service is running. for Windows OS, you can check the docker-desktop service using, Get-Service "Docker Desktop Service" To start the docker desktop service on the windows run the below command. Start-Serv ..read more

You can set environment variables in Azure Pipeline so they can be used in the scripts and application code. This variable is process level means it is available during that pipeline run only. To set environment variables in Azure Pipeline, the env variable is used in the steps subtasks. Below are the steps subtasks. steps: [ task | script | powershell | pwsh | bash | checkout | download | downloadBuild | getPackage | publish | template | reviewApp ] Let’s take some examples to understand the same. Using the env variable at the task level trigger: - none pool: vmImage: windows-latest jo ..read more

There are two types of arrays in PowerShell. Fixed array Dynamic Array Fixed Array Fixed arrays are the ones whose values cannot be removed or added. Their sizes are fixed. For example, below is the fixed-size array. $array1 = @("Cat","Dog","Cow") If you try to add/remove elements, it will fail. $array1.add("Tiger") Some programs you write may need the array dynamically allocated so the elements can be added or removed when needed. ArrayList This dynamic array is called the arraylist in PowerShell. There are two ways to create dynamic arrays (ArrayList). $array2 =New-Object -TypeNam ..read more

In the previous articles, we mentioned setting up environment variables using PowerShell and Python in Windows OS. In this article, we will set up environment variables with GoLang. Set up environment variables with GoLang. a. Process Level Setting up environment variables at the process level is easy with GoLang. Below is an example of that. package main import ( "fmt" "os" ) func main(){ env_key := "azSub" env_value := "TestSub1" err := os.Setenv(env_key,env_value) if err != nil { fmt.Println("Error Setting up process level ..read more

In the previous article, we have seen how to set the environment variables with GUI, PowerShell, and CMD. In this section, let’s continue to set the environment variable programmatically using Python Set Environment Variable using Python a. Process Level Setting up environment variables at the process level is easy with Python. We need to import the OS module and use the environment function to set the value. For Example, import os os.environ["azSub"] = "TestSub1" print(os.environ["azSub"]) Setting up environment variables at the machine or user levels isn’t straightforward in Python like ..read more

What is an environment variable in Windows? In Windows, an environment variable is a map/hash kind of variable with a Key-Value pair that stores the values of the variable inside the operating system so that the applications or processes can use it. There are three types of environment variables. Machine Level (Permanent) User Level (Permanent) Process Level (Temporary) Process level has the highest preference while the User level is the second and third is the machine level. So if the same variable is set across the three levels with different values then the Process level will be given th ..read more

Why do we need an Azure DevOps (ADO) extension in Azure CLI? Well, you know how to manage Azure DevOps services (Pipeline, workItems, Repo, Artifacts, etc) from the portal. If you are a DevOps engineer or Automation guy then you would love to manage the ADO services with the command line (Azure CLI). Managing ADO services with the command line is very easy and makes your work faster like managing pipelines, work items, artifacts, etc. Pre-Requisites: Azure CLI Tool installed (must be above 2.10.1). Azure DevOps Account Once you have Azure CLI installed, you are eligible to install the exten ..read more
