Knitting socks with needle size 100 would be extremely challenging, as this needle size is much larger than what is typically used for sock knitting. The resulting fabric would be very loose and open, and the socks would likely be too large and not fit properly. It would be best to use a much smaller needle size, such as US 1 (2.25mm) or US 2 (2.75mm), to achieve the tight gauge and small stitches needed for a well-fitting and durable pair of socks. **

In Python, numbers from 0001 to 9999 can be represented using the built-in `str.zfill()` method. This method pads the string representation of a number with zeros to a specified width. For example, to represent the number 1 as "0001", you can use `str(1).zfill(4)`. Similarly, to represent the number 9999 as "9999", you can use `str(9999).zfill(4)`. This method ensures that the numbers are represented with leading zeros to maintain a consistent width. **
