我收到 SyntaxError: (unicode error) 'unicodeescape' codec

Question

您好，我正在编写一个即将到期的简单代码。我正在使用 Wing IDE 4.1.3-1，运行程序代码时不断收到此消息

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-4: truncated \UXXXXXXXX escape (, line 4)

这是我的程序：

#=====================================================================
# Program:      Calculating Sales
# Programmer:   Viet-Anh Tran
# Date:         2-14-2012
#               July 1, 2011 - Revised for Python 3
# Abstract:     This program processes highest sales, lowest sales,
#               and averages the total numnber of sales. Each
#               salesperson will be asked enter the amount they sold
#               and the price of each sale.
#=====================================================================

def main():
    #create variable to control loop
    keep_going = 'y'
    #process each salperson's sales
    while keep_going == 'y' or keep_going == 'Y':
        #use a function to process sales
        show_sales()
        keep_going = input("would you like to calculate another salesperson's" +
        "sales? (enter y or Y as yes to continue) ")
#define show_sales
def show_sales():
    #ask for name of salesperson
    name = input("What is the salesperson's name? ")
    #ask for first sales amount
    print('Enter', name, "'s first sale amount: ")
    first_sale = float(input())
    #when assigning a value for first sale make sure its bewtween 1-25000
    while first_sale < 1 or first_sale > 25000:
        #prompt error message if it does not meet within range
        print('ERROR: First sale amount must fall in the range of $1-$25,000.')
        #ask user again for CORRECT amount
        print('Please enter', name, "'s correct first sale amount:")
        first_sale = float(input())
    #assign all total highest and lowest sales to first sale
    total_sale = first_sale
    highest_sale = first_sale
    lowest_sale = first_sale

    print('Are there any more sales? If so, type in the total number of sales:')
    number_sales = int(input())
    #create a loop
    for sale in range(2, number_sales + 1):
        print('What is', name, "'s next sales amount?")
        sales_amount = float(input())
        #again make sure that it is within range and ask the correct amount again
        while sales_amount < 1 or first_sale > 25000:
            print('ERROR: Sale amount must fall in the range of $1-$25,000.')
        print('Please enter', name, "'s correct sale amount:")
        sales_amount = float(input())
        #accumulate the total sales
        total_sales += sales_amount
        #this assigns the lowest and highest value to the correct variable
        if sales_amount > highest_sale:
            highest_sale = sales_amount
        if sales_amount < lowest_sale:
            lowest_sale = sales_amount
    #calculate average and print highest, lowest, and average
    average_sales = total_sales / number_sales
    print(name, "'s highest sale: $", format(highest_sale, ',.2f'), sep='')
    print(name, "'s lowest sale: $", format(lowest_sale, ',.2f'), sep='')
    print(name, "'s sale on average: $", format(average_sale, ',.2f'), sep='')

Answer 1

File "<string>" 表明你的程序正在通过exec 运行，很可能是通过一个字节字符串传递到那里的。所以这可能是 IDE 中的一个疏忽。

错误的原因可能是您姓名中的特殊字符。 Python 3 无论如何都应该处理这个问题，但 Wing IDE 似乎试图让代码与 Python 2 兼容......但失败了。

当然，这主要是推测，但您应该考虑在命令行中运行您的脚本，而不需要任何 IDE。我做到了，并且成功了。

Answer 2

这是 Wing 4.1.3 中的一个错误，可以通过使用“帮助”菜单中的“检查更新”来修复。
