Your answer can be solved via a HTTP request from Python.

You need to send some sort of metadata for the worksheet via HTTP.
For example, get the ID of the worksheet using Python, and send the following info:
<entry>
<id>
https://spreadsheets.google.com/feeds/worksheets/key/private/full/worksheetId
</id>
<updated>2007-07-30T18:51:30.666Z</updated>
<category scheme="http://schemas.google.com/spreadsheets/2006"
term="http://schemas.google.com/spreadsheets/2006#worksheet"/>
<title type="text">Income</title>
<content type="text">Expenses</content>
<link rel="http://schemas.google.com/spreadsheets/2006#listfeed"
type="application/atom+xml" href="https://spreadsheets.google.com/feeds/list/key/worksheetId/private/full"/>
<link rel="http://schemas.google.com/spreadsheets/2006#cellsfeed"
type="application/atom+xml" href="https://spreadsheets.google.com/feeds/cells/key/worksheetId/private/full"/>
<link rel="self" type="application/atom+xml"
href="https://spreadsheets.google.com/feeds/worksheets/key/private/full/worksheetId"/>
<link rel="edit" type="application/atom+xml"
href="https://spreadsheets.google.com/feeds/worksheets/key/private/full/worksheetId/version"/>
<gs:rowCount>45</gs:rowCount>
<gs:colCount>15</gs:colCount>
</entry>
The website has a Java and .NET solution as well. (This is for the legacy version 3)
For the newer version, you can use a batch update via a POST http request from Python as well.
link is here
The data for the request is
{
"requests": [{
"updateSpreadsheetProperties": {
"properties": {"title": "My New Title"},
"fields": "title"
}
}]
}
to be sent via POST to https://sheets.googleapis.com/v4/spreadsheets/spreadsheetId:batchUpdate
In both requests, replace the spreadsheetId in the URL with the ID of the Google Sheet you are editing.
Notice the change from v3 to v4 in the URLs.
If you are using a version 3 application and want to migrate, the link to that is here
EDIT
A commentor noted that the second request does not change name of a worksheet. The link I added shows the way to change intricate properties of a worksheet, I will be updating my answer soon.
