SyntaxError: Non-UTF-8 code starting with '\x91'
提问by GrapeSoda3
I am trying to write a binary search program for a class, and I am pretty sure that my logic is right, but I keep getting a non-UTF-8 error. I have never seen this error and any help/clarification would be great! Thanks a bunch.
我正在尝试为一个类编写一个二进制搜索程序，我很确定我的逻辑是正确的，但我不断收到非 UTF-8 错误。我从未见过这个错误，任何帮助/澄清都会很棒！谢谢一堆。
Here's the code.
这是代码。
def main():
str names = [‘Ava Fischer', ‘Bob White', ‘Chris Rich', ‘Danielle Porter', ‘Gordon Pike', ‘Hannah Beauregard', ‘Matt Hoyle', ‘Ross Harrison', ‘Sasha Ricci', ‘Xavier Adams']
binarySearch(names, input(str("Please Enter a Name.")))
print("That name is at position "+position)
def binarySearch(array, searchedValue):
begin = 0
end = len(array) - 1
position = -1
found = False
while !=found & begin<=end:
middle=(begin+end)/2
if array[middle]== searchedValue:
found=True
position = middle
elif array[middle] >value:
end=middle-1
else:
first =middle+1
return position

Your editor replaced '(ASCII 39) with U+2018 LEFT SINGLE QUOTATION MARKcharacters, usually a sign you used Word or a similar wordprocessor instead of a plain text editor; a word processor tries to make your text 'prettier' and auto-replaces things like simple quotes with fancy ones. This was then saved in the Windows 1252 codepage encoding, where the fancy quotes were saved as hex 91 characters.
您的编辑器将'(ASCII 39)替换为U+2018 LEFT SINGLE QUOTATION MARK字符，通常是您使用 Word 或类似文字处理器而不是纯文本编辑器的标志；文字处理器试图使您的文本“更漂亮”，并自动用花哨的引号替换简单的引号之类的内容。然后将其保存在Windows 1252 代码页编码中，其中花哨的引号保存为 16 进制 91 字符。
Python is having none of it. It wants source code saved in UTF-8 and using 'or "for quotation marks. Use notepad, or better still, IDLE to edit your Python code instead.
Python 一无所有。它希望以 UTF-8 格式保存源代码并使用'或"作为引号。使用记事本或更好的 IDLE 来编辑您的 Python 代码。
You have numerous other errors in your code; you cannot use spaces in your variable names, for example, and Python uses and, not &as the boolean AND operator. !=is an operator requiring 2 operands (it means 'not equal', the opposite of ==), the boolean NOT operator is called not.
您的代码中还有许多其他错误；例如，您不能在变量名中使用空格，并且 Python 使用and, 而不是&作为布尔 AND 运算符。!=是一个需要 2 个操作数的运算符（它的意思是“不等于”，与 的相反==），布尔非运算符被称为not。

Add this line at the top of you code. It may work.
在代码顶部添加此行。它可能会起作用。
# coding=utf8

The character you are beginning your constant strings with is not the right string delimiter.You are using
您开始常量字符串的字符不是正确的字符串分隔符。您正在使用
‘Ava Fischer' # ‘ and ' as string delimiters
when it should have been either
当它应该是
'Ava Fischer' # Ascii 39 as string delimiter
or maybe
或者可能
"Ava Fischer" # Ascii 34 as string delimiter

If you're using Notepad++, click Encodingat the top and choose Encode in UTF-8.
如果您使用的是 Notepad++，请单击Encoding顶部的 并选择Encode in UTF-8。
