如何修復此錯誤：TypeError: unsupported operand type(s) for *: 'float' and 'function' in python

如何解決此 TypeError

TypeError: unsupported operand type(s) for *: 'float' and 'function'

這是我的代碼：

#calculate overtime pay
def overtime_pay(weekly_pay, regular_rate, overtime_hrs ):
  overtime_p = weekly_pay + ((regular_rate*1.5)*overtime_hrs)
  print('Overtime pay for ' + total_hrs_per_wk + 'hours worked' + 'is: \t', overtime_pay)
  return overtime_p

Answer 1

您的意思是這里的最后一個變量是overtime_p嗎？

print('Overtime pay for ' + total_hrs_per_wk + 'hours worked' + 'is: \t', overtime_pay)

Answer 2

您的代碼片段缺少一些重要信息，例如“total_hrs_per_wk”以及調用此 function 的支持代碼。 所以，我使用了一些藝術許可來填補缺失的部分。 以下是利用您的加班 function 以及一些修訂的代碼片段。

#calculate overtime pay
def overtime_pay(weekly_pay, regular_rate, overtime_hrs ):
    total_hrs_per_wk = float(weekly_pay / regular_rate + overtime_hrs) # This variable was missing - added it
    overtime_p = weekly_pay + ((regular_rate*1.5)*overtime_hrs)
    print('Total pay with overtime for ', total_hrs_per_wk, 'hours worked is: \t', overtime_p)  # Made the last variable "overtime_p" instead of the function name
    return overtime_p

# Created the following code to execute the function with floating point variables
    
weekly_pay = float(input("Enter weekly pay: "))
regular_rate = float(input("Enter worker rate: "))
overtime_hrs = float(input("Enter overtime hours: "))

overtime_pay(weekly_pay, regular_rate, overtime_hrs)

以下是從代碼片段中刪除的一些內容。

• 由於沒有“total_hrs_per_wk”的定義，因此添加了一個計算，通過將工人的正常工作時間與加班時間相加來得出一周的總小時數。
• 由於變量“total_hrs_per_wk”包含一個數值而不是一個字符串，因此 print 語句被更改為將值打印為數字而不是您最初指定的字符串。
• 打印語句中的最后一個變量“overtime_pay”被更正為“overtime_p”。 “overtime_pay”是您的 function 的名稱，打印該值只會打印出 function 定義詳細信息，而不是您所追求的加班費。

試試看。

補充說明。

為了回應關於“total_hrs_per_week”是一個返回值而不是變量的 function 的評論，下面是一個修改后的代碼片段，它等效於上述代碼片段，但調用名為“total_hrs_per_wk”的 function 並使用返回的值.

# Have total weekly hours as a function instead of a variable
def total_hrs_per_wk(pay, reg_rate, total_hrs):
    return float(total_hrs - pay / reg_rate)

#calculate overtime pay
def overtime_pay(weekly_pay, regular_rate, overtime_hrs ):
    total_hr = float(weekly_pay / regular_rate + overtime_hrs)
    overtime_p = weekly_pay + ((regular_rate*1.5)*overtime_hrs)
    print('Total pay with overtime for ', total_hr, 'hours worked is: \t', overtime_p)  # Made the last variable "overtime_p" instead of the function name
    return overtime_p

# Created the following code to execute the function with floating point variables
    
weekly_pay = float(input("Enter weekly pay: "))
regular_rate = float(input("Enter worker rate: "))
overtime_hrs = float(input("Enter overtime hours: "))

overtime_pay(weekly_pay, regular_rate, total_hrs_per_wk(weekly_pay, regular_rate, (40 + overtime_hrs))) # Last parameter will be the result of a function call

測試導致終端上顯示相同的值。 如前所述，這只是獲得相同結果的眾多方法之一。
