Data analysis with Excel

 To analyze data in Excel, you don't need to be an expert in Excel. You just need to know a few functions and tools to get the job done. Compare with financial analysts, they are very expert in excel and they create financial models and staff. They need to know all the shortcuts, functions, designs, layouts and many of them can work in Excel without touching the mouse. But you don't have to be that level of expert to analyze data with Excel. Before you start working with Excel, first see how many different versions of Excel are available. There are different versions of Excel but Excel 2007(Windows), 2008(MAC), 2010(Windows), 2011 (MAC), Excel 2016, Excel 2019, and Excel 365 are the most popular. Excel 365 is advanced but you can use any version. Let's start with Excel… Excel Layout:   First we need to understand Excel layout. At the very top of Excel, that section is called the "Quick Access Toolbar." By default, that section has three menus Save (Ctrl S), Undo (...

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 ...

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...
