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，但是我总是得到一个非UTF-8错误。我从来没有见过这个错误，任何帮助/澄清都是很好的！谢谢。

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
