pythonimport json
def check_first_name(json_obj, target_char): try: first_name=json_obj['firstName'] return target_char in first_name except KeyError: return False
示例JSON字符串json_str='{firstName: John, lastName: Doe}'
目标字符target_char='o'
将JSON字符串转换为Python对象json_obj=json.loads(json_str)
调用函数并输出结果result=check_first_name(json_obj, target_char)print(result) # 输出：True
