I am a bike seller and I use serial numbers for my bikes. Occasionally people raise a support ticket with issues and I need them to include their bike serial number. However, they mostly, with the hyphens in the wrong place, some letters lowercase etc. I need a quick script to format my serial numbers correctly.
def format_serial_number(serial, l): ... The serial numbers need to be grouped into sections of length l separated by dashes -, except for the first section that may be shorter if the string cannot be split into equal parts of length l. It must also all be in upper case.
For example, running the function should return the values as below:
IN : format_serial_number('7Hnwad9Jk', length=4) OUT: "7-HNWA-D9Jk"
IN : format_serial_number('6F2k-1d-0-z', length=4) OUT: "6F2K-1D0Z"
IN : format_serial_number('14k-9-b', length=2) OUT: "1-4K-9B"
