示例程式碼 1.1

TempStr = input("Please input the temperature with the suffix C or F: "
 
)
if TempStr[-1] in ['F', 'f']:
    C = (eval(TempStr[0: -1]) - 32) / 1.8
    print("It is equal to {:.2f}C".format(C))
elif TempStr[-1] in ['C', 'c']:
    F = 1.8 * eval(TempStr[0: -1]) + 32
    print("It is equal to {:.2f}F".format(F))
else:
    print("Grammatical error!"
 
)

給一種和書上不完全一樣的方法

TempStr = 'Y'
while True:
    TempStr = input("Please input the temperature with the suffix C or F. (Enter N to exit)\nTemperature: ")
    if TempStr[-1] in ['N', 'n']:
        break
    if TempStr[-1] in ['F', 'f']:
        C = (eval(TempStr[0: -1]) - 32
 
) / 1.8
        print("It is equal to {:.2f}C".format(C))
    elif TempStr[-1] in ['C', 'c']:
        F = 1.8 * eval(TempStr[0: -1]) + 32
        print("It is equal to {:.2f}F".format(F))
    else:
        print("Grammatical error!")
