The syntax of Python is straightforward and resembles that of English. Python's syntax differs from various other programming languages in that it enables programmers to construct applications with fewer lines of code. Python operates on an interpreter system, allowing for the immediate execution of written code. As a result, prototyping can proceed quickly. Python is popular for Rapid Application Development and as a scripting or glue language to tie existing components together because of its high-level, built-in data structures, dynamic typing, and dynamic binding. Python  syntax is also used for server-side web development, software development, mathematics, and system scripting.
