面对'TypeError: can only concatenate str (not

This error message is occurring because you’re trying to concatenate a non-string object with a string. In Python, strings are concatenated using the + operator.

Here’s an example causing this error:

  1. num = 5
  2. str_to_concat = "Hello,"
  3. # Concatenating a non-string with a string
  4. result = num + str_to_concat
  5. print(result)

In this code, num is not a string, so trying to concatenate it with the string str_to_concat raises a TypeError.
