A method of converting the specified string to uppercase in Python and getting a new string separated by a space every 2 characters

In the example, for the specified string:

Faa5fbb5fcc5fdd5010200000028000001900000000a002d00000000017d7840000003e800005fa55fb55fc55fd5

Three methods were used to convert them to uppercase letters and each 2 characters were separated with a space to get a new string, as follows:

FA A5 FB B5 FC C5 FD D5 E8 xx (xx) 0A xx 2D xx xx xx (7D)----5F A5 5F B5 5F C5 5F D5

In order to verify the efficiency of three methods, the original string is expanded to 100 times times the length, and then 10,000 processing, from its time-consuming results, the first method is the slowest, the second to third method is better.

Code:

The results of the operation are as follows:
