根因分析

测试函数尝试将整数和字符串相加，未经显式转换不允许。

English

A test function tries to add an integer and a string, which is not allowed without explicit conversion.

generic

解决方案

  1. 95% 成功率 Convert string to int before addition 
    result = 5 + int('3')
  2. 90% 成功率 Ensure type consistency in test data 
    a = 5; b = 3; result = a + b

无效尝试

常见但无效的做法:

  1. Using str() on both operands 50% 失败

    Converts both to strings, resulting in concatenation instead of addition.

  2. Using int() on string without validation 60% 失败

    If string is not numeric, int() raises ValueError.
