Python CMD 语法错误

Question

在用 Python 编写代码时，我在 CMD 中遇到了这个错误

Project11.py", line 5
    if Select == 1
                 ^
SyntaxError: invalid syntax

这是我的完整程序

print("Canadian to USD")

Select = input("Press 1 for Canadian to USD or 2 for USD to Canadian ")

if Select == 1
    Canadian1 = input("Canadian ")

    USD1 = int(Canadian1) * 0.63674
    print("{0}$ = ${1}".format(Canadian1, USD1))

if Select == 2
    USD2 = input("USD ")

    Canadian2 = int(USD2) * 1.5704
    print("${0}={1}$".format(USD2, Canadian2))

有人可以纠正错误或帮助我吗？谢谢:)

Answer 1

您需要在 if Select == "1" 和 if Select == "2" 之后加上引号和冒号。

所以你的代码应该是这样的:

print("Canadian to USD")

Select = input("Press 1 for Canadian to USD or 2 for USD to Canadian ")

if Select == "1":
    Canadian1 = input("Canadian ")

    USD1 = int(Canadian1) * 0.63674
    print("{0}$ = ${1}".format(Canadian1, USD1))

if Select == "2":
    USD2 = input("USD ")

    Canadian2 = int(USD2) * 1.5704
    print("${0}={1}$".format(USD2, Canadian2))
