Interview Coding Questions & Answers — Python

In IT industry, almost every technical interview has few programming or scripting questions depending on the role(ex: DevOps engineer, SRE) you apply. Python is a popular language among software developers and system engineers because it is relatively easy to learn. Python is used to write scripts to automate repetitive or manual tasks of engineers. So that, I wrote some simple yet most commonly asked python questions in DevOps or SRE interviews.
