Question

有很多类似的问题。这里有两个：

Python Error: AttributeError: 'NoneType' object has no attribute 'to_excel'

AttributeError: 'Object has no attribute'

我想用excel文件列标题中的空格替换下划线，然后保存。代码如下：

import pandas as pd

ws = r'c:/users/jpilbeam/Reverse911_1a_English_.xlsx'

# data frame from excel file 
df3 = pd.read_excel(ws, header=0) 
#remove underscores
df2 = df3.columns.str.replace("_", " ")
## save to file
df2.to_excel(df2)

这是完整的错误：

Traceback (most recent call last):
  File "\\pathto\Python Scripts\C19VaccinationTable.py", line 18, in <module>
    df2.to_excel(df2)
AttributeError: 'Index' object has no attribute 'to_excel'

在调试时，我注意到脚本将成功打印 columns.str.replace() 函数。但是，它不会写入excel文件。

Answer 1

$domain = 'test.ru'; $values = [ 'WMONID' => 'nRiQPgfdbrq', 'EUOBGSPNSESSIONID'=>'pc1PrDd8VGeeVvONfQSptl7fIOxBla_tcfvJ6GqViXWeLBGojsP\u00211681227827\u00211177731283' ]; $cookieJar = \GuzzleHttp\Cookie\CookieJar::fromArray($values, $domain); $client = new \GuzzleHttp\Client([ 'base_uri' => 'https://test.ru', ]); $response = $client->get('/endpoint',[ 'cookies' => $cookieJar ] 是一个索引对象 (pandas.Index)，因此当您替换 df3.columns 时，它返回一个索引对象。而是这样做：

要查看它是如何工作的，您可以跟踪每个步骤：

import pandas as pd

ws = r'c:/users/jpilbeam/Reverse911_1a_English_.xlsx'

# data frame from excel file 
df3 = pd.read_excel(ws, header=0) 
#remove underscores
df3.columns = df3.columns.str.replace("_", " ")
## save to file
df3.to_excel(filename)   # filename being the file name you want to save it in.

AttributeError: 'Index' 对象没有属性 'to_excel'
