为什么我的字符串比较在 Python 中不起作用？

Question

我根据调查数据用Python编写了一个简单的代码

`
 # Load CSV data 
 csv_file = 'women_survey.csv' 
 data_women = pd.read_csv(csv_file)

 # Convert object to String 
 data_women['physical_Assault'] = data_women['physical_Assault'].astype("string")
 w_marital_status = data_women['physical_Assault']

 # print sample data size and type
 print(w_marital_status.shape)
 print(w_marital_status.dtype)
 # person 1's data
 print(w_marital_status[0])    

 # Create a new List
 new_list = [""] * 62

 # Read each iteration of survey data and assign String to new List
 for count, content in enumerate(w_marital_status, start=0):
    new_test = content.split(":", 1)[1]
    new_list[count] = new_test
    print(new_test)
   if type(new_test) == str:
     if new_test == "Yes":
        print("This is a Yes")
     else:
        print("This is a No")
   else:
     print("This is not a string.")`

此代码提供以下结果（部分）。

(62,)
string
Have you ever been physically assaulted?: No

No

This is a No
No

This is a No
No

This is a No
No

This is a No
Yes

This is a No

如结果所示，对于每个人，每一行都包含整个问题“您是否曾受到身体攻击？”以及附加的答案“是”或“否”

我只想存储答案“是”或“否”，以便稍后使用 MatplotLib 并绘制数据图表。所以我编写了 For 循环来将答案分配给一个新列表。但正如您所看到的，字符串比较永远不会起作用。我不确定“new_test”是否实际上是一个字符串，事实证明它是一个字符串，但字符串比较仍然不起作用。我不太确定我做错了什么。另外，如果有比我的代码更简单的方法，请告诉我。谢谢。

试试这个：

new_list = list()

# Read each iteration of survey data and assign String to new List
 for content in w_marital_status:
    new_test = content.split(":", 1)[1]
    new_list.append(new_test)
    print(new_test)
   if type(new_test) is str:
     if new_test.strip().lower() == "yes":
        print("This is a Yes")
     else:
        print("This is a No")
   else:
     print("This is not a string.")`
