A code example can vary depending on the language and context. Here is an example of a basic “Hello World” program in Python:

python
 
 
Copy code
# This is a program that prints out Hello World
print("Hello World")

This example would print the string “Hello World” when run.

To resize images, there are several ways you can do this. One way is to use an online editor such as Fotor. You can upload images and resize them to the desired dimensions. You can also crop, rotate, adjust clarity, sharpen and adjust colors.

Alternatively, you can use software such as GIMP, an open source image editor. With GIMP, you can open an image and click on Image > Scale Image to resize your image.

You can also use a variety of programming libraries such as the Python Pillow library to resize images. This can be done with the code snippet below:

python
 
 
Copy code
from PIL import Image

image = Image.open('my_image.jpg') # Open image file
new_image = image.resize((200, 200)) # Resize to 200 x 200
new_image.save('resized_image.jpg') # Save the new image

Python is a high-level, interpreted general-purpose programming language. It is an open source language designed for easy readability and can be used for a wide variety of programming tasks, from web development to system administration and data analysis. Python is popular for its clean syntax and easy readability. It is a multi-paradigm language that supports object-oriented, procedural, and functional programming styles.

In Python, you can convert an integer to a string using the str() function. For example, if you have a = 5 and you want to convert it to a string, you simply use a = str(5).

python
 
 
Copy code
a = 5
a = str(5)
print(a)

This would output '5'. You can also do this by casting the integer as a string like a = '5'.

There are a variety of free image databases API's available.

One option is the Pixabay API. Pixabay offers hundreds of thousands of free stock photos, vectors, and art illustrations. It supports several programming languages including JavaScript, PHP, Python, Java, Ruby, Node.js, and C#.

Another option is the Flickr API. Flickr offers millions of free publicly available photos, with photos from users around the world. It also supports a variety of API's including REST API, JSON API, and XML API.

RFC3339 is a standard for formatting timestamps usually used in APIs. To read timestamps in this format, parse it as a string into a DateTime data structure using a language-specific library. In Python, using the datetime package, this can be done using the fromisoformat method:

python
 
 
Copy code
from datetime import datetime
timestamp = datetime.fromisoformat("YYYY-MM-DDTHH:MM:SS.sssssssss")

A function is a self-contained block of code that performs a specific task. In programming, functions allow you to easily reuse code instead of rewriting the same code multiple times.

For example, in Python a function could be defined like this:

python
 
 
Copy code
def my_function():
    print("Hello World")

my_function()

When my_function() is called, it will print "Hello World" to the terminal. Functions make programming more efficient as they can be reused as needed and make code easier to reason about and debug. More info here.

An array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. Arrays are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched. In most programming languages, the elements in an array are usually of the same data type, although in some languages they may be of different data types. Depending on the language, array types can overlap (such as a variable length array and a static array). More information can be found here.

python
 
 
Copy code
city = 'Toulouse'
country = 'France'
print("I am from %s, in %s" %(city, country))

In many programming languages (such as C, C++, and Python), you can add a unit parameter to a function by including an argument in the function definition. For example, the following Python function definition includes an argument called unit, which can be used to pass a unit to the function.

python
 
 
Copy code
def convert_temp(temperature, unit):
    # Logic to convert temperature from Fahrenheit to Celsius
    return converted_temp

Once the function is defined, you can call the function with a valid unit argument, such as convert_temp(32, 'F').

Functional programming is a programming paradigm which emphasizes the use of functions, and treats computation as the evaluation of mathematical expressions. Functional programming often avoids changing-state and mutable data and focuses on expressions, hence “functions” and “functionals” are interchanged. Imperative programming utilizes assignments to change and update the states. Functional programming avoids this by not changing things and having no side effects.

Some languages that implement functional programming are Python, Clojure, Erlang, Haskell, Lisp, and more.

Functional programming is a programming paradigm which emphasizes the use of functions that produce and transform data. It is focused on describing how a program operates and is made up of expressions. Object-oriented programming is a programming paradigm that is focused on objects with their own identity and properties that interact with each other through methods. It is focused on how a program is structured rather than what it does and is made up of objects that contain both data and functions.
