regex - Python: hexadecimal regular expression question -


I want to parse the output of a serial monitoring program called doclight (I highly recommend this) This 'hexadecimal' string Does output: or a sequence (two capital hex points after a space) This is the regular expression: ([0- 9A-F] {2}) + For example: '05 03 dA 4 B3F '

< P> When the program detects specific sequences of characters, it gives comments in the 'hexadecimal' string. For example: 

  '05 03 04 01 A Header 03 08 B BD Air Force Payment 0 D Footer '

The format is '. + ' (one sequence of characters before a space and after one place)

I have to get rid of the comments. For example, the 'hexadecimal' string above the filter will be: 

  '05 03 04 01 A 03 08 B.BDFDDA '
< P> How do I do this with a regular expression?

You can try: 

  & gt; & Gt; & Gt; A = '05 03 04 01 A Header 03 08 B BD Air Force PAD 0A Powder '& gt; & Gt; & Gt; ('05', '03', '04', '01', '0A', '03' '' B [0- 9A-F] {2} In regular expressions,  \ b  one matches the "word boundary". 
 
 Of course, your input is unclear if the serial monitor is something  this BE THE HEADER .

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
