Python version 3.10 introduced theTypeAliasdeclaration to make type aliases more explicit and distinct from regular variables. Here’s how you can use it: Python fromtypingimportTypeAliasEmailComponents:TypeAlias=tuple[str,str]|None You need to importTypeAliasfrom thetypingmodule before you can use...
In general, a function takes arguments (if any), performs some operations, and returns a value (or object). The value that a function returns to the caller is generally known as the function’s return value. All Python functions have a return value, either explicit or implicit. You’ll ...
Python functions can return values, which allows you to retrieve information or the result of a computation from the function. Sometimes, you may wantyour function to return a key-value pair, a common data structure used in Python dictionaries. Key-value pairs help link pieces of related inform...

We have discussed ways to handle variables and the best practices for naming variables in Python. We have noticed a number of searches on the site for how
Normal declaration of variables causes the memory to be allocated at the compile time.void *malloc(size_t size); The malloc() function returns a generic void pointer. To assign values of a certain data type in the allocated memory, it must be typecast to the required type. For example, ...
This is fine, and we can get the values in this way thanks to array destructuring:const [age, name] = getDetails()Now we have the age and name variables that contain those values.Note that the order we define those in const [age, name] = getDetails() matters....

In our case, the reference variable was the array from the createArray function, while the original variable was the testArray from the useArray function. We used the nameref to indirectly manipulate variables without using complex workarounds. You can find more details here. Using Global Varia...
It takes anarrayas an argument which can be a 1-D or 2-D array containing multiple variables and observations. Each row of the array represents a variable, and each column is a single observation of all those variables. If we pass 3 different 1-dimensional arrays in this method simultaneou...
