python - 有人可以用 python 和 google sheets api 帮助我解决这个问题吗？

Question

问题

我正在测试谷歌工作表并尝试制作一个删除所有代表的过滤器，只在工作表上留下参议员。我正在使用此 sheet 中的信息:

代码

import gspread
from oauth2client.service_account import ServiceAccountCredentials
from pprint import pprint

scope = ["https://spreadsheets.google.com/feeds",'https://www.googleapis.com/auth/spreadsheets',"https://www.googleapis.com/auth/drive.file","https://www.googleapis.com/auth/drive"]

creds = ServiceAccountCredentials.from_json_keyfile_name("creds.json", scope)

client = gspread.authorize(creds)

sheet = client.open("Congress").sheet1  # Open the spreadhseet

data = sheet.get_all_records()  # Get a list of all records

rowCount = sheet.row_count

val = sheet.col_values(1)


i = 1
for value in val:
    if value == 'rep':
        print('Deleted:', sheet.cell(i,1).value, sheet.cell(i,5).value)
        sheet.delete_row(i)
    i = i +1

我得到:

Deleted: rep Young
Deleted: rep Roby
Deleted: rep Aderholt
Deleted: rep Palmer
Deleted: sen Jones
Deleted: rep Crawford
Deleted: rep Womack

它基本上只删除了我在下面加粗的那些:

它应该删除所有具有“rep”的行，但最终并没有删除所有行，它还删除了一些具有“sen”的行。 我该如何解决这个问题？

Answer 1

您在遍历行时正在删除行。剩余的行向上移动 - 这会扰乱你的索引 - 你跳过一些行并删除其他行:

例子:

line 0   rep     someone
line 1   rep     someone
line 2   sen     someone

你 for 循环遍历你的行: - 你测试第 0 行，你删除第 0 行，第 1 行变成第 0 行 - 你接下来测试第 1 行 - 太棒了，它是一个 sen - 你跳过了(原来是 1，现在是 0 行)

等等

改为从后面删除:

import gspread
from oauth2client.service_account import ServiceAccountCredentials
from pprint import pprint

scope = ["https://spreadsheets.google.com/feeds",
         'https://www.googleapis.com/auth/spreadsheets',
         "https://www.googleapis.com/auth/drive.file",
         "https://www.googleapis.com/auth/drive"]

creds = ServiceAccountCredentials.from_json_keyfile_name("creds.json", scope)

client = gspread.authorize(creds)

sheet = client.open("Congress").sheet1  # Open the spreadhseet

data = sheet.get_all_records()  # Get a list of all records

rowCount = sheet.row_count

val = sheet.col_values(1)

for idx,value in reversed(list(enumerate(val,1))):
    if value == 'rep':
        print('Deleted:', sheet.cell(idx,1).value, sheet.cell(idx,5).value)
        sheet.delete_row(idx)
