我在寫一個應該刪除重複條目的腳本。數據中的一些人已經輸入了兩次他們的名字,因爲他們有兩個電話號碼,並且由於電話號碼字段不是數組,所以輸入多個時,他們輸入了多個條目。如何處理「Nonetype」錯誤?
我的腳本使用與列名相對應的鍵將條目更改爲詞典,然後遍歷每一行。有一個主循環遍歷每一行,然後是一個嵌套for循環,遍歷每個元素的所有元素,比較它們以檢測重複。當我點擊一個副本時,我的代碼應該比較手機,電子郵件和網站,然後將它們附加到某個區域(如果它們是唯一/不匹配的)。
這裏是我的代碼:
import csv
# This function takes a tab-delim csv and merges the ones with the same name but different phone/email/websites.
def merge_duplicates(sheet):
myjson = [] # myjson = list of dictionaries where each dictionary
with(open("ieca_first_col_fake_text.txt", "rU")) as f:
sheet = csv.DictReader(f,delimiter="\t")
for row in sheet:
myjson.append(row)
write_file = csv.DictWriter(open('duplicates_deleted.csv','w'), ['name','phone','email','website'], restval='', delimiter = '\t')
for row in myjson:
# convert phone, email, and web to lists so that extra can be appended
row['phone'] = row['phone'].split()
row['email'] = row['email'].split()
row['website'] = row['website'].split()
print row
for i in len(myjson):
# if the names match, check to see if phone, em, web match. If any match, append to first row.
try:
if myjson[i]['name'] == myjson[i+1]['name']:
if myjson[i]['phone'] != myjson[i+1]['phone']:
myjson[i]['phone'].append(myjson[i+1]['phone'])
# if row['email'] != myjson[rowvalue+1]['email']:
# row['email'].append(myjson[rowvalue+1]['email'])
# if row['website'] != myjson[rowvalue+1]['website']:
# row['website'].append(myjson[rowvalue+1]['website'])
except IndexError:
print("We're at the end now")
write_file.writerow(row)
merge_duplicates('ieca_first_col_fake_text.txt')
所以一切都會在我的代碼花花公子,然後它遇到第一個副本,我得到這個錯誤:
{'website': [], 'phone': [], 'name': 'Diane Grant Albrecht M.S.', 'email': []}
{'website': ['www.got.com'], 'phone': ['111-222-3333'], 'name': 'Lannister G. Cersei M.A.T., CEP', 'email': ['[email protected]']}
{'website': [], 'phone': [], 'name': 'Argle D. Bargle Ed.M.', 'email': []}
{'website': ['www.daManWithThePlan.com'], 'phone': ['000-000-1111'], 'name': 'Sam D. Man Ed.M.', 'email': ['[email protected]']}
Traceback (most recent call last):

感謝這麼多的幫助!

只是檢查以確保,但我不知道這是錯誤,因爲輸出顯示有條目沒有電話號碼。但錯誤不會發生。如果有幫助,我已經用數據更新了這篇文章。 – goldisfine
你的棧跟蹤清楚地顯示了'row''email'] = row ['email']。split()'這意味着'''''''''''''沒有' – karthikr
也沒有''''和'None'一樣。所以,空白電話號碼不一定意味着它是'沒有' – karthikr
