To split a list into N chunks in Python, you can use iterators: Notice that it isn’t always possible to produce a list where the chunks are equal in length. This is because the list elements might not be evenly divisible to the N chunks. This is a comprehensive guide to splitting a list into […]

To check the size of a file in Python, use the os.path.getsize() method. This method takes the path of the file as an argument and returns the size of the file in bytes. The os module is part of the standard library. Thus, you do not need to install it. It is available out of

Python does not have traditional increment and decrement operators, like ++ or –. Instead, Python uses augmented assignment operators, which combine the assignment operator (=) with a mathematical operation, such as addition (+=) or subtraction (-=). For example, to increment a variable x by 1, you can use the augmented assignment operator x += 1

In Python, the dir() function returns a list of the attributes and methods that belong to an object. This can be useful for exploring and discovering the capabilities of an object, as well as for debugging and testing. For example, let’s list the attributes associated with a Python string: Output: The result is a complete

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
