使用sep=""即可

附上程式:

a,b,c=map(int,input().split())
if b**2-4*a*c>0:
    x1=int((-b+(b**2-4*a*c)**0.5)/2*a)
    x2=int((-b-(b**2-4*a*c)**0.5)/2*a)
    print("Two different roots x1=",x1," , x2=",x2,sep="")
elif b**2-4*a*c==0:
    x=int(-b/2*a)
    print("Two same roots x=",x,sep="")
elif b**2-4*a*c<0:
    print("No real root")
