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 –.

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
