(there is also a alternative if you tell the script to print out the numbers adding by 1 it will tell you 158729 then stop) script below↓↓↓
i = 1 while i < 9999999999: print(i) i += 1
if that is what you meant by biggest number even though this one just makes the script end at that but this may also be on the version or type of python program you run it on
