I've written the following code:
The output would be: Z1.371 Y-1.279 X-0.0003 U-0.0003
This works, but now I'm expanding on the idea and it seems like I'm doing double the work dealing with the negative numbers.
Is there a better way to deal with the negative? My new program will need to format the text, arranging the strings into arrays where the data types = float.
import re res_pos = r'(X)(\d+\.\d*)' res_neg = r'(X-)(\d+\.\d*)' def grab_pos(line, pattern=res_pos): result = re.search(pattern, line) num = result.group(2) if result else None return num def grab_neg(line, pattern=res_neg): result = re.search(pattern, line) num = result.group(2) if result else None return num with open ('GCODE.txt', 'rt') as infile, open('GCODE_OUT.txt', 'w') as outfile: for line in infile: result_pos = grab_pos(line) result_neg = grab_neg(line) if result_pos: subs = re.sub(r'(X)(\d+\.\d*)', 'X'+result_pos+' U'+result_pos, line) outfile.write(subs) elif result_neg: subs = re.sub(r'(X-)(\d+\.\d*)', 'X-'+result_neg+' U-'+result_neg, line) outfile.write(subs) else: outfile.write(line)An example of the input text might be: Z1.371 Y-1.279 X-0.0003
The output would be: Z1.371 Y-1.279 X-0.0003 U-0.0003
