Python comment

Python comments are used to provide additional information about your code, and they are not executed by the Python interpreter. There are two types of comments in Python: single-line comments and multi-line comments.

Single-line comments begin with the hash symbol (#) and continue until the end of the line. They are often used to explain what a particular line of code does. For example:


```
# This line prints 'Hello, world!'
print("Hello, world!")
```

Multi-line comments, also known as block comments, are used to provide more detailed explanations of code. They start and end with three consecutive quotation marks (""") and can span multiple lines. For example:

```
"""
This is an example of a multi-line comment. It can be used to provide more detailed explanations of code or to temporarily disable a section of code.

print("This code is currently disabled.")
"""

print("Hello, world!")
```

It is important to use comments in your code to make it more understandable and easier to maintain. Well-written comments can help you and other developers understand the purpose and functionality of your code, making it easier to modify or update in the future.

There are different ways to comment multiple lines of code in Python depending on the text editor or IDE you are using. Here are some common methods:


1. Comment multiple lines shortcut on Mac:

On Mac, you can use the following shortcut to comment multiple lines in Python:
- Select the lines of code you want to comment
- Press the keys "Command" and "/" at the same time
This will add the hash symbol (#) to the beginning of each line, commenting them out.

2. Comment multiple lines in Python VSCode:

In Visual Studio Code, you can comment multiple lines of code in Python using the following steps:
- Select the lines of code you want to comment
- Press the keys "Command" and "K" followed by "Command" and "C" on Mac, or "Ctrl" and "K" followed by "Ctrl" and "C" on Windows/Linux
This will comment out the selected lines using the hash symbol (#).

3. Comment multiple lines shortcut in PyCharm:

In PyCharm, you can use the following shortcut to comment multiple lines of code in Python:
- Select the lines of code you want to comment
- Press the keys "Command" and "/" on Mac, or "Ctrl" and "/" on Windows/Linux
This will add the hash symbol (#) to the beginning of each line, commenting them out.

It's important to note that Python comments end at the end of the line, so any code after the comment on the same line will not be executed. Additionally, commenting out code can be useful for debugging or temporarily disabling sections of code, but it's generally not recommended to leave commented-out code in your program for long periods of time as it can clutter your code and make it harder to read.

Legal drinking age around the world

From hard liquor to hard seltzer, alcoholic beverages are an almost ubiquitous part of many modern cultures: wine with dinner, beer with friends on the weekend, celebratory champagne toasts, etc. However, because alcohol is a drug that can significantly affect a person's judgment and physical abilities, many countries age-restrict the consumption of alcoholic beverages. Effects of alcohol on the body In chemical terms, alcohol is an organic compound produced when grains, vegetables or fruits are allowed to ferment. Medically, alcohol is classified as a depressant (as opposed to stimulants like caffeine or hallucinogens like psilocybin) with a wide range of physiological effects. Most of these effects involve a reduction or inhibition of physical activity. For example, alcohol inhibits physical motor function and slows reaction time. Consequently, the more one drinks, the slower and more sluggish one becomes. Similarly, alcohol also inhibits the brain's communication pathways. T...

Python - Output Variables

Output variables in Python refers to the process of displaying or printing the value of a variable to the console or output stream. This is a crucial aspect of programming as it allows developers to test and debug their code and also helps users to interact with the program. In Python, we can output variables to the console using the print() function. The syntax for using the print() function is straightforward: ``` variable_name = "Hello, World!" print(variable_name) ``` In this example, we have created a variable called `variable_name` and assigned it the value "Hello, World!". We then use the print() function to output the value of `variable_name` to the console. We can also output multiple variables using the print() function by separating them with commas. For example: ``` name = "John" age = 25 print("My name is", name, "and I am", age, "years old.") ``` In this example, we have created two variables called `name` and `a...

Python - Global Variables

In Python, a global variable is a variable that is declared outside of any function and can be accessed by any function in the same module or file. Global variables can be useful for storing values that are needed by multiple functions within the same module or file. In Python, declaring a variable outside of any function is all that's needed to create a global variable: ``` # defining a global variable my_global_var = "Hello World" # Creating a function that utilizes the global variable: def print_global_var():     print(my_global_var) # calling the function print_global_var()  # output: "Hello World" ``` In the example above, `my_global_var` is a global variable that can be accessed by the function `print_global_var()` because it is defined outside of any function. It is also possible to modify the value of a global variable from within a function using the `global` keyword: ``` # defining a global variable my_global_var = "Hello World" # defining a ...
