How to convert the "±" into "+-" or vice versa in a python string?
For example I have this string 18.1±0.3% hemolysis at 50µM and only want to split ± in this string +-.
This is not splitting. You call it so, because, graphically, it looks that way. But there is not other relation (other than appearance in your fonts) between '±' and '+' and '-'.
So what you are looking for, is just good, old, pattern search and replace.
mystring.replace('±', '+-')
