使用google-apis for google sheets，如何根据条件更新特定单元格

from google.oauth2 import service_account
from googleapiclient.discovery import build

# 读取私钥文件并进行身份验证
credentials = service_account.Credentials.from_service_account_file(
    'path/to/service_account_key.json',
    scopes=['https://www.googleapis.com/auth/spreadsheets']
)

# 创建服务客户端
service = build('sheets', 'v4', credentials=credentials)

spreadsheet_id = 'your_spreadsheet_id'
sheet_name = 'your_sheet_name'

# 更新特定单元格的值
request = service.spreadsheets().values().update(
    spreadsheetId=spreadsheet_id,
    range=sheet_name + '!A1',
    valueInputOption='RAW',
    body={'values': [['New Value']]}
)
response = request.execute()

# 获取特定单元格的当前值
request = service.spreadsheets().values().get(
    spreadsheetId=spreadsheet_id,
    range=sheet_name + '!A1'
)
response = request.execute()
current_value = response['values'][0][0]

# 根据条件更新特定单元格的值
if current_value == 'Old Value':
    request = service.spreadsheets().values().update(
        spreadsheetId=spreadsheet_id,
        range=sheet_name + '!A1',
        valueInputOption='RAW',
        body={'values': [['New Value']]}
    )
    response = request.execute()
