Question

代码中有3个错误，请您帮助我找到它们，我只是一个初学者。我需要将Var中的字母附加（连接）到名称列表，这是一个列表变量。但是由于我是一个字符串，所以似乎存在问题。

namelist = []

var1 = input( "Enter the name you want to validate ").upper()

namelist.append(var1[0])

for i in var1[1:]:
  for j in (namelist):
     if(j>=i):
       namelist.insert(i,namelist.index(j))
       break
     else:
       i.append(namelist)

print(namelist)

预期结果：快速运行代码以重新排列名称中的字母

Answer 1

首先，请为变量使用明确的名称。您到底想使用代码实现什么？

您可以使用以下代码获取字母列表：

Bitmap bmp = BitmapFactory.DecodeFile(f);
Mat img = new Mat();
img = BitmapConverter.ToMat(bmp);

并使用以下命令将变量设置为相反：

NameList = []
Input = input("Enter the name you want to validate:\n").upper()
for Character in Input:
    NameList.append(Character)
print(NameList)

Answer 2

您似乎想反转字符串

有几种方法，这里有一些基本的for循环

main.js:49 Uncaught TypeError: speechEvents.off is not a function
    at Object.stopped_speaking (main.js:49)
    at harker.emit (hark.js:16)
    at hark.js:109

输出：

namelist = []
var1 = input( "Enter the name you want to validate ").upper()
for i in range(1, len(var1) + 1):
    namelist.append(var1[len(var1) - i])
print (namelist)
print ("".join(namelist))

。

Enter the name you want to validate Hello
['O', 'L', 'L', 'E', 'H']
OLLEH

输出：

namelist = ''
var1 = input( "Enter the name you want to validate ").upper()
for i in range(1, len(var1) + 1):
    namelist = namelist + var1[len(var1) - i]
print (namelist)

。

Enter the name you want to validate hello
OLLEH

输出：

def reverse(text):
    rev_text = ""
    for char in text:
        rev_text = char + rev_text
    return rev_text

print (reverse("hello"))
