KeyError："筛选器"(从数据帧接收特定数据)

Question

所以，顺序是"要求用户输入他/她希望接收数据的对象的名称和过滤器的名称;需要的数据(可以引入多个过滤器)。">

这是我的数据:

我运行了下面的代码，一切都为我工作

import pandas as pd
def searchByFilter():
filter = input('Enter filter to show data n')
df = pd.DataFrame({"Dummy":[1,2,3,4,5],
"Filter":["A","B","C","D","E"]})
print(df.loc[df['Filter'] == filter,:])

print('Enter 1 to search by object name')
print('Enter 2 to search by filter')
src = (input('Enter here: '))
if src == '1':
None
elif src == '2':
searchByFilter()
else:
print('Sorry, invalid input')
-----------------------------------
Enter 1 to search by object name
Enter 2 to search by filter
Enter here: 2
Enter filter to show data 
B
Dummy Filter
1      2      B

关键错误表明您的'Python_2ndLab.csv'文件头可能没有完全按照预期格式化。再次检查文件，确保没有任何可能导致这种情况的前导或尾随空格。在文本编辑器中打开CSV而不是excel，可以更容易地发现这些。
