[issue41289] '%' character in help= for argparse causes ValueError: incomplete format

[Neil Godber]

New submission from Neil Godber :

'%' character in help= for argparse causes ValueError: incomplete format. I am 
attempting to use the percentage character in my help string but get the above 
error. Presumably argparse assumes % denotes formatting when this is not the 
case. I have tried f-strings, escape and raw strings, none of which rectify the 
issue. The only solution is that dev's cannot use % character in argpase help 
strings which is something of an oddity.

Hi, yes I did just then and indeed this worked. Wasn't aware of this. Further, 
curiously I am no longer able recreate this issue so I will close this for now. 
Sorry for the bother.
