Question

I am using Python and regex to try and search for text. Given the string within a text file:

line = (<layerThickness> 0.58 </layerThickness>)

I am trying to assign 0.58 to variable L, however the output is consistently, “<_s” rather than the decimal value. This is what I have been trying:

L = re.search(r"([-+]?[0-9]*\.?[0-9]+)", line)

Any help is appreciated!

Answer 1

Perhaps you just need to call the .group() method:

import re
line = '(<layerThickness> 0.58 </layerThickness>)'
L = re.search(r"([-+]?[0-9]*\.?[0-9]+)", line).group(0)
print(L)

yields

0.58
