Is Python a

What Python AddsThe one new syntax component in Python is the colon character (:). All Python compoundstatements (i.e., statements that have statements nested inside them) followthe same general pattern of a header line terminated in a colon followed by a nestedblock of code usually indented underneath the header line, like this:Header line:Nested statement blockThe colon is required, and omitting it is probably the most common coding mistakeamong new Python programmers—it’s certainly one I’ve witnessed thousands oftimes in Python training classes. In fact, if you are new to Python, you’ll almost certainlyforget the colon character very soon. Most Python-friendly editors make thismistake easy to spot, and including it eventually becomes an unconscious habit (somuch so that you may start typing colons into your C++ code, too, generating manyentertaining error messages from your C++ compiler!).What Python RemovesAlthough Python requires the extra colon character, there are three things programmersin C-like languages must include that you don’t generally have to in Python.Parentheses are optionalThe first of these is the set of parentheses around the tests at the top of the statement:if (x < y)The parentheses here are required by the syntax of many C-like languages. InPython, they are not—we simply omit the parentheses, and the statement works thesame way:if x < yTechnically speaking, because every expression can be enclosed in parentheses,including them will not hurt in this Python code, and they are not treated as an errorif present. But don’t do that: you’ll be wearing out your keyboard needlessly, andbroadcasting to the world that you’re an ex-C programmer still learning Python (Iwas once, too). The Python way is to simply omit the parentheses in these kinds ofstatements altogether.End of line is end of statementThe second and more significant syntax component you won’t find in Python code isthe semicolon. You don’t need to terminate statements with semicolons in Pythonthe way you do in C-like languages:x = 1;204 | Chapter 10: Introducing Python Statements
