秋梨膏，看看这个python代码怎么改

将判断语句重新调整一下，代码可以这样写：

print('choice area 1.east,2.south,3.north')
area=int(input('area number:'))
weight=int(input('goods weight:'))
f1_0=13;f2_0=12;f3_0=14

if weight>3:
    if area==1:
        f=f1_0+(weight-3)*3
    elif area==2:
        f = f2_0+(weight-3)*2
    else:
        f = f3_0+(weight-3)*4
else:
    f=f1_0 if area==1 else f2_0 if area==2 else f3_0
print(f)

把源码贴出来

print("请选择地区：-华东地区（编号1）-华南地区（编号2）-华北地区（编号3）")

area = int(input("请输入地区编号："))
weight = int(input("物品重量（kg）："))
a0 = 0
b0 = 0
c0 = 0
a1 = ('华东地区')
a2 = ('华南地区')
a3 = ('华北地区')
b1 = 13
b2 = 12
b3 = 14
c1 = 13+(weight-3)*3
c2 = 12+(weight-3)*2
c3 = 14+(weight-3)*4
if area == 1:
    a0 = a1
elif area == 2:
    a0 = a2
elif a0 == 3:
    a0 = a3

if area == 1:
    b0 = b1
elif area == 2:
    b0 = b2
elif area == 3:
    b0 = b3

if area == 1:
    c0 = c1
elif area == 2:
    c0 = c2
elif area == 3:
    c0 = c3

if weight<=3 and weight>0:
    print("快递至[%s]"%a0)
    print("费用为[%d]"%b0,"元")
else:
    print("快递至[%s]" % a0)
    print("费用为[%d]" %c0, "元")
