To get the size of a Python object, you can use the getsizeof() function from the sys module. This function returns the size of an object in bytes. For example, let’s print the size of a list and the size of an integer: Output: ⚠️ Keep in mind that sys.getsizeof() function only returns the size […]

You can place an if…else statement into a list comprehension in Python. For example: Notice that the if…else statement in the above expression is not traditional if…else statement, though. Instead, it’s a ternary conditional operator, also known as the one-line if-else statement in Python. Example Given a list of numbers, let’s construct a list of

In Python, a dictionary is a collection of key-value pairs. Both dictionary.get(‘key’) and dictionary[‘key’] are used to retrieve the value associated with a given key in a dictionary. However, there is a clear difference between the two: To put it short, dictionary.get(‘key’) is the safer way to get value from a dictionary. You shouldn’t use

In Python, you can use sys.maxsize from the sys module to get the maximum and minimum integer values. The sys.maxsize gives you the maximum integer value and its negative version -sys.maxsize – 1 gives you the minimum integer value. Notice that Python 3.0+ doesn’t limit the int data type and there’s no maximum/minimum value. But

To find all files with a particular extension in Python, you can use the os.walk function to traverse the directory structure, and check if each file has the desired extension using the file.endswith() method. For example, let’s find all the .txt files: This will print the full path of all files with the .txt extension
