Question

请告诉我它有什么问题。因为当我运行它时它会告诉错误。在线＆＃34;如果小时＆gt; 40＆＃34;并说它的语法错误！

while true:
    hrs = input ("Enter no.of hrs worked: ")
    rate = input ("Enter the rate per hour: ")
    try:
        hrs = int(hrs)
        rate = int(rate)
        raise ValueError("Non numeric value")
    except enter code hereValueError as e:
        print (e)
        continue
if hrs > 40
    # anything over 40 hrs earns the overtime rate
    overtimeRate = 1.5 * rate
    overtime = (hrs-40) * overtimeRate
    # the remaining 40 hrs will earn the regular rate
    hrs = 40
    regular=hrs*rate
    total_pay=regular+overtime
    print(total_pay)
    else:
        # if you didn't work over 40 hrs, there is no overtime
        overtime = 0
        total_pay=hrs*rate
        print(total_pay)
  quit()

Answer 1

您的代码包含一些语法和语义错误：

布尔值true应以大写字母True开头。
编写代码的方式非常重要，并且应该以正确的方式进行格式化，每条指令之前的空间都是敏感的，即同一块中的代码前面应该有相同的空格数。
通过在raise块中使用try，您创建了一个始终执行的自定义异常，并且永远不会到达if块。
在except关键字后，您有两个选项：
- 要么设置例外名称，例如：
except ValueError: print("Non-numeric data found in the file.")
- 或者不指定例外并将其留空

您输入代码的正确方法是：

while True:
    hrs = input ("Enter no.of hrs worked: ")
    rate = input ("Enter the rate per hour: ")
    try:
        hrs = int(hrs)
        rate = int(rate)
        #raise ValueError("Non numeric value")
    except :
        print ('Non numeric data found.')
        continue    
    if hrs > 40:
        # anything over 40 hrs earns the overtime rate
        overtimeRate = 1.5 * rate
        overtime = (hrs-40) * overtimeRate
        # the remaining 40 hrs will earn the regular rate
        hrs = 40
        regular=hrs*rate
        total_pay=regular+overtime
        print(total_pay)
    else:
        # if you didn't work over 40 hrs, there is no overtime
        overtime = 0
        total_pay=hrs*rate
        print(total_pay)
    quit()

希望它有所帮助！

一些错误......

你在if statement的末尾错过了一个冒号。此外，else不应该是indented。最后，我纠正了您的try except声明，因为您无缘无故地提升ValueError :)。现在，如果输入无法成功转换为ints，则ValueError将被引发，loop将继续（如果没有错误，则代码将继续并{{1}离开循环）。

所以最终的代码是：

break

我认为这就是你要找的东西：

do_action( 'woocommerce_before_single_product_summary' );

Answer 4

你不应该使用加注但只是尝试除了+使用正确的缩进（如果一个else）将永远不会在你的情况下使用（仅在循环时）。试试版本：

while True:
hrs = input ("Enter no.of hrs worked: ")
rate = input ("Enter the rate per hour: ")
try:
    hrs = int(hrs)
    rate = int(rate)

except ValueError as e:
    print (e)
    print("Non numeric value")
    continue
if hrs > 40:
    # anything over 40 hrs earns the overtime rate
    overtimeRate = 1.5 * rate
    overtime = (hrs-40) * overtimeRate
    # the remaining 40 hrs will earn the regular rate
    hrs = 40
    regular=hrs*rate
    total_pay=regular+overtime
    print(total_pay)
else:
    # if you didn't work over 40 hrs, there is no overtime
    overtime = 0
    total_pay=hrs*rate
    print(total_pay)
