头歌python答案 实验6：Python函数

第1关：温度转换

# 请在此添加代码
########## Begin ##########
def convert(c):
    f=1.8*c+32
    return f

########## End ##########
C = eval(input( "input a number:" ))
F = convert( C )
print( "%.1f"%F )

第2关：求五边形的面积

# 请在此添加代码
from math import *
########## Begin ##########

# 计算三角形的面积
def ts(a,b,c):
    s = (a + b + c) / 2
    area = sqrt(s * (s - a) * (s - b) * (s - c))
    return area

# 主函数
def main():
    k1, k2, k3, k4, k5, k6, k7 = map(int, input().split(','))
    a1 = k1
    b1 = k2
    c1 = k6
    a2 = k3
    b2 = k7
    c2 = k6
    a3 = k5
    b3 = k4
    c3 = k7
    area = ts(a1, b1, c1) + ts(a2, b2, c2) + ts(a3, b3, c3)
    print("area=%.5f" % area)

########## End ##########
main()

第3关：匿名函数应用
