Method of Outputting Multiple Formatting Parameters with print of in python

No nonsense, just post the code:

disroot = math.sqrt(deta)
root1 = (-b + disroot)/(2*a)
root2 = (-b - disroot)/(2*a)
print(" There are two different solutions : %.2f,%.2f"%root1,%root2) 

This is the original print () code, but the runtime always prompts TypeError

Later, I searched a lot of information on the Internet and found that the format was not like this at all, which I took for granted

   disroot = math.sqrt(deta)
root1 = (-b + disroot)/(2*a)
root2 = (-b - disroot)/(2*a)
print(" There are two different solutions : %.2f,%.2f"%(root1,root2))
