2. Python syntax and semantics - Wikipedia

   en.wikipedia.org/wiki/Python_syntax_and_semantics

   Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...

3. Python (programming language) - Wikipedia

   en.wikipedia.org/wiki/Python_(programming_language)

   Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [ 70] and metaobjects ). [ 71] Many other paradigms are supported via extensions, including design by ...

4. For loop - Wikipedia

   en.wikipedia.org/wiki/For_loop

   t. e. In computer science, a for-loop or for loop is a control flow statement for specifying iteration. Specifically, a for-loop functions by running a section of code repeatedly until a certain condition has been satisfied. For-loops have two parts: a header and a body. The header defines the iteration and the body is the code that is executed ...

5. Duck typing - Wikipedia

   en.wikipedia.org/wiki/Duck_typing

   Type systems. In computer programming, duck typing is an application of the duck test —"If it walks like a duck and it quacks like a duck, then it must be a duck"—to determine whether an object can be used for a particular purpose. With nominative typing, an object is of a given type if it is declared as such (or if a type's association ...

6. Syntax (programming languages) - Wikipedia

   en.wikipedia.org/wiki/Syntax_(programming_languages)

   Syntax definition. Parse tree of Python code with inset tokenization. The syntax of textual programming languages is usually defined using a combination of regular expressions (for lexical structure) and Backus–Naur form (a metalanguage for grammatical structure) to inductively specify syntactic categories ( nonterminal) and terminal symbols ...

7. Conditional (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Conditional_(computer...

   For example: If stock=0 Then message= order new stock Else message= there is stock End If In the example code above, the part represented by (Boolean condition) constitutes a conditional expression , having intrinsic value (e.g., it may be substituted by either of the values True or False ) but having no intrinsic meaning.

8. "Hello, World!" program - Wikipedia

   en.wikipedia.org/wiki/"Hello,_World!"_program

   For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!" In contrast, the equivalent code in C++ [ 7 ] requires the import of the input/output (I/O) software library , the manual declaration of an entry point , and the explicit instruction that the output string should be ...

9. Machine code - Wikipedia

   en.wikipedia.org/wiki/Machine_code

   In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers machine code is "the binary representation of a computer program which is actually read and interpreted by the computer.
