用python编写一个简单的温度（华氏-摄氏/摄氏-华氏）转换程序。
代码如下：
#-*- charset:utf-8 -*-
#This program will follow users intention to convert F to C or the contray
typeNo = eval(input("Do you want to convert Fah to Cel or convert Cel to Fah,enter 1 for F to C,enter 2 for C to F:"))
if typeNo == 1:
data = eval(input("Please enter your data:"))
c = (data - 32) * 5 / 9
print(data,"Fahrenheit to Celsius is:",round(c,1)," C")
elif typeNo == 2:
data = eval(input("Please enter your data:"))
f = data * 9 / 5 + 32
print(data,"Celsius to Fahrenheit is:",round(f,1)," F")
elif (typeNo != 1) and (typeNo != 2):
print("Input error!")
