如何解决 TypeError: can only concatenate str (not "int") to str [英] How to resolve TypeError: can only concatenate str (not "int") to str

问题描述

• 我决定使用 Unicode 制作某种密码以进行测试.
• 我已经通过向 Unicode 添加数字来做到这一点，所以这将是一种秘密.
• 我一直收到此错误，但我不知道如何解决.
  • 有什么解决办法吗?

  message = input("Enter a message you want to be revealed: ")
  secret_string = ""
  for char in message:
      secret_string += str(chr(char + 7429146))
  print("Revealed", secret_string)
  q = input("")
  

  原始错误

  ---------------------------------------------------------------------------
  TypeError                                 Traceback (most recent call last)
  <ipython-input-182-49ece294a581> in <module>
        2 secret_string = ""
        3 for char in message:
  ----> 4     secret_string += str(chr(char + 7429146))
        5 print("Revealed", secret_string)
        6 q = input("")
  
  TypeError: can only concatenate str (not "int") to str
  

  更新代码

  while True:
      try:
          message = int(input("Enter a message you want to be decrypt: "))
          break
      except ValueError:
          print("Error, it must be an integer")
  secret_string = ""
  for char in message:
      secret_string += chr(ord(char - str(742146)))
  print("Decrypted", secret_string)
  q = input("")
  

  推荐答案

  Python 与 JavaScript 的工作方式有点不同，例如，您连接的值需要是相同的类型，都是 int 或 str...

  Python working a bit differently to JavaScript for example, the value you are concatenating needs to be same type, both int or str...

  例如下面的代码抛出错误:

  print( "Alireza" + 1980)
  

  像这样:

  Traceback (most recent call last):
    File "<pyshell#12>", line 1, in <module>
      print( "Alireza" + 1980)
  TypeError: can only concatenate str (not "int") to str
  

  要解决此问题，只需将 str 添加到您的数字或值中，例如:

  To solve the issue, just add str to your number or value like:

  print( "Alireza" + str(1980))
  

  结果如下:

  Alireza1980
