Kateri Python modul se uporablja za generiranje naključnih števil?

random

Kako v Pythonu definiramo funkcijo znotraj razreda?

class MyClass: def add_numbers(self, x, y): return x + y

Katera visokonivojska funkcija v Pythonu aplicira dano funkcijo na vsak element v iterabilni strukturi?

map()

Kaj omogočajo moduli v Pythonu?

Sestavljajo skupino funkcij, razredov in konstant, ki olajšajo organizacijo in vzdrževanje programov.

Kako v Pythonu vključimo zunanji modul v naš program?

S pomočjo import module_name.

Kaj je potrebno storiti pred uporabo funkcije iz modula v Pythonu?

Modul mora biti uvožen s import in funkcija poklicana z imenom modula ter imenom funkcije ločenima s piko.

Podatkovni tip bool predstavlja celi številski podatkovni tip v Pythonu.

False

V Pythonu, nizovi so predstavljeni s podatkovnim tipom list.

False

Podatkovni tip tuple v Pythonu omogoča spreminjanje elementov po inicializaciji.

False

V Pythonu, za enovrstične komentarje uporabljamo simbol //.

False

Kontrolna struktura for v Pythonu se uporablja za iteracijo čez elemente v podatkovni strukturi.

True

Python podpira različne kontrolne strukture, med njimi tudi goto izjava.

False

Funkcija v Pythonu se vedno konča z besedo end.

False

elif je krajšava za else if v Pythonu.

True

Moduli v Pythonu so lahko le standardni moduli kot npr. math.

False

for zanka v Pythonu se uporablja samo za iteracijo po seznamih.

False

Python Programming: A Deep Dive into Syntax, Data Types, Functions, and Modules

Python programming, widely renowned for its simplicity and versatility, has become a popular choice in data science, web development, and AI applications. In this article, we'll explore the basics of Python, focusing on syntax, data types, functions, and modules.

Syntax Python has a clean and readable syntax, making it easy for beginners to grasp. The language follows a standard set of rules that define how code should be written. For example, Python uses indentation to define code blocks such as loops and conditionals, unlike many other programming languages that use curly braces for this purpose.

Data Types Python provides various data types to store and manipulate data. Some of the most common data types are:

  • Integer (int)
  • Float (float)
  • String (str)
  • List (list)
  • Tuple (tuple)
  • Dictionary (dict)
  • Set (set)

Functions Functions are reusable blocks of code that help with code organization and avoiding redundant code. Python functions can take arguments, return values, and be defined both inside and outside of classes.

Module System Python's module system makes it easy to reuse code in a modular way. A module can be seen as a collection of functions, classes, and constants that can be imported and used in your code. Some popular Python modules include:

  • os: For interacting with the operating system
  • sys: For system-specific parameters and functionality
  • math: For mathematical functions
  • random: For generating random numbers

Control Structures Python supports various control structures, including:

  • if/else statements
  • for loops
  • while loops
  • break and continue statements
  • Switch statement (although more versatile, Python uses match instead)

Functions Python's functions are essential for code organization and reuse. Functions can be defined in the following ways:

  • Defining functions outside of classes:

    def calculate_sum(x, y):
        return x + y
    
  • Defining functions inside classes:

    class MyClass:
        def add_numbers(self, x, y):
            return x + y
    

Higher-Order Functions Python's higher-order functions are a powerful feature that allows functions to accept other functions as arguments or return functions as results. Some examples of higher-order functions are:

  • map(): Applies a function to each item in an iterable
  • filter(): Filters items from an iterable based on a condition
  • reduce(): Applies a function cumulatively to the items of an iterable

Decorators Python's decorators are a way to add functionality to existing functions. Decorators are defined using the @ symbol, and they can be applied to transform the behavior of a function, add logging, or even create new functions.

Summary Python is a powerful and versatile language with an emphasis on readability and simplicity. Its syntax, data types, functions, and modules make it a great choice for data science, web development, and many other applications. By mastering these basics, you'll be well on your way to becoming a proficient Python programmer.

Explore the fundamental aspects of Python programming, covering syntax, data types, functions, and modules. Learn about Python's clean and readable syntax with emphasis on indentation for code blocks, various data types like integers, strings, and dictionaries, the importance of functions for code organization, and the module system for code reusability.
