Answer 1

您以错误的方式输入货币。替换为以下代码：

amount = int(input("Please enter an amount to convert"))

if con=='a':
    print(amount,'converts to ',amount*0.57)

此外，要添加更多货币类型，而不是输入所有内容，只需将它们以这种方式放入数组中：

currencies = [['CAD','GBP'],['CAD','USD'],['CAD','JPY'],['CAD','EUR']]
for i in range(len(currencies)):
    print(i+1,' ',currencies[i][0],' to' ,currencies[i][1])
    #change alphabet to integers
con = int(input("Please select the type of conversion"))
if con == 1:
    print(amount,' ',currencies[i-1][0], converts to ',currencies[i-1][1],amount*0.57)
