练习1: Python基本语法元素 (第1周)

实例1: 温度转换

a= input()
if a[-1] in ['f','F']:
        b = (eval(a[0:-1])-32)/1.8
        print("{:.2f}C".format(b))
elif a[-1] in ['c','C']:
        b = eval(a[0:-1]) *1.8+32
        print("{:.2f}F".format(b))
else:
        print("输入格式错误")

数字形式转换 I

string = "零一二三四五六七八九"
a = input()
for i in a:
    print( string[eval(i)],end="")

温度转换 II

 a = input()
if a[0] in ['c','C']:
    b = eval(a[1:]) * 1.8 +32
    print("F{:.2f}".format(b))
elif a[0] in ['f','F']:
    b = (eval(a[1:]) - 32) /1.8
    print("C{:.2f}".format(b))

货币转换 I

a = input()
if a[0:3] == "RMB":
    b = eval(a[3:]) /6.78
    print("USD{:.2f}".format(b))
elif a[0:3] == "USD":
    b = eval(a[3:])  *6.78
    print("RMB{:.2f}".format(b))
