Summary
Computer programming has evolved from low-level machine languages to modern high-level languages such as Python. Tools for coding programs in these high-level languages often use visual elements such as parentheses, spacing, and highlighting to help people understand and create the hierarchical structures that underlie most modern programming languages. Programming environments also use visual cues, such as highlighting changes in the program’s data as it runs, to help programmers find and fix errors.
