你这玩意都输出 0 了（

@continue_and_break 把int去掉能拿80分，还有一个re

你int会让他直接去尾

@continue_and_break 然后re，我不会用Python

@无敌的蒟蒻 3_2_1!

x1,y1=map(float,input().split())
x2,y2=map(float,input().split())
x3,y3=map(float,input().split())
d1=((x1-x2)**2+(y1-y2)**2)**0.5
d2=((x1-x3)**2+(y1-y3)**2)**0.5
d3=((x3-x2)**2+(y3-y2)**2)**0.5
print("%.2f"%(d1+d2+d3))

放弃用自定义

print("{:.2f}".format((int(dis(x1,x2,y1,y2)+dis(x1,x3,y1,y3)+dis(x2,x3,y2,y3)))))

这个int是哪里的要求？

@continue_and_break 输入输出的时候都要用浮点数类型
