8.16 python基础

不同进制的数相加

num1,num2 = input().split()
num1 = int(num1,16)
num2 = int(num2,8)
print(num1 + num2)

 // ——整除

 移位运算符

计算2的num次方

---

num = int(input())
print(2 << num-1)

 f"{:}"

print(f"{highest:.2f} {lowest:.2f} {average:.2f}")

 已知三边，计算三角形面积

a,b,c = input().split()
a = int(a)
b = int(b)
c = int(c)
cir = (a+b+c)/2
#海伦公式
area = (cir*(cir-a)*(cir-b)*(cir-c))**0.5
#算式中不可以包含中括号
print(f"circumference={cir*2:.2f} area={area:.2f}")
