The term 'POPULAR PROGRAMMING LANGUAGE' can be solved by the 6-letter word 'PYTHON'. PYTHON is a high-level, general-purpose programming language that was created in 1991 by Guido van Rossum. It is an interpreted language, meaning that it does not need to be compiled before it is run. PYTHON is widely used for web development, data science, scripting, and automation. It is also popular among beginners due to its simple syntax and readability.
