This can result in: def mac_conv(mac, sep='-'):

Other than the above function, you don't need to use f.readlines() you can just use f. I'd then join the last three lines into one.Īs return and '.'.join are easy to understand in a single one-liner.

Perform a list comprehension to join the sliced segments together.

Slice segments into a three item list.

To do this I would base my algorithm around the use of a list comprehension. As you will find later, although they look cumbersome, they have many advantages at the development stage of software writing (especially when trying to locate errors in the code).The only thing I'd change is to reduce the amount of lines. Machine code and assembly code are examples of low-level languages and are used by software developers when producing, for example, computer games. Here is a simple example:Ī5E4 FFA4 (machine code using hexadecimal values)ġ010 0101 1110 0100 1111 1111 1010 0100 (machine code using binary) It is also very easy to mistype the digits in a ‘sea of 1s and 0s’. Using true machine code (which uses binary) is very cumbersome and it takes a long time to key in the values.

Using hexadecimal makes it much easier, faster and less error prone to write code compared to binary. This can have many advantages to program developers or when carrying out troubleshooting. Machine code and assembly code are covered in much more detail later on in the course, but they are essentially low-level languages that directly access the memory chips in the computer here we are simply interested in how hexadecimal fits into the picture. Computer memory can be referred to directly using machine code or assembly code.
