[英]FileNotFoundError: [Errno 2] No such file or directory with ABSOLUTE file path
[英]“FileNotFoundError:[Errno 2] No such file or directory in windows” on constructed path
我的文件路徑是
C:/Users/Ratul/Downloads/Machine_Learning_Data/reddit_data/reddit_data/
該目錄中有許多文件夾。 我需要瀏覽這些目錄並打開以“ RC_”開頭的文件
這是我的代碼:
import sqlite3
import json
import os
from datetime import datetime
timeframe = '2015-05'
sql_transaction = []
connection = sqlite3.connect('{}.db'.format(timeframe))
c = connection.cursor()
def create_table():
c.execute("CREATE TABLE IF NOT EXISTS parent_reply(parent_id TEXT PRIMARY KEY, comment_id TEXT UNIQUE, parent TEXT, comment TEXT, subreddit TEXT, unix INT, score INT)")
def format_data(data):
data = data.replace('\n',' newlinechar ').replace('\r',' newlinechar ').replace('"',"'")
return data
def find_parent(pid):
try:
sql = "SELECT comment FROM parent_reply WHERE comment_id = '{}' LIMIT 1".format(pid)
c.execute(sql)
result = c.fetchone()
if result != None:
return result[0]
else: return False
except Exception as e:
#print(str(e))
return False
if __name__ == '__main__':
create_table()
row_counter = 0
paired_rows = 0
with open('C:/Users/Ratul/Downloads/Machine_Learning_Data/reddit_data/reddit_data/{}/RC_{}'.format(timeframe.split('-')[0],timeframe), buffering=1000) as f:
for row in f:
row_counter += 1
row = json.loads(row)
parent_id = row['parent_id']
body = format_data(row['body'])
created_utc = row['created_utc']
score = row['score']
comment_id = row['name']
subreddit = row['subreddit']
parent_data = find_parent(parent_id)
# maybe check for a child, if child, is our new score superior? If so, replace. If not...
if score >= 2:
existing_comment_score = find_existing_score(parent_id)
但似乎這條道路上有一些錯誤。 我得到一個錯誤
追溯(最近一次通話最近):文件“ C:/Users/Ratul/AppData/Local/Programs/Python/Python37/test02.py”,第36行,其中open('C:/ Users / Ratul / Downloads / Machine_Learning_Data /reddit_data/reddit_data/{}/RC_{}'.format(timeframe.split('-')[0],timeframe),buffering = 1000)as f:FileNotFoundError:[Errno 2] No such file or directory:' C:/用戶/ Ratul /下載/ Machine_Learning_Data / reddit_data / reddit_data / 2015 / RC_2015-05'
我不確定在那做錯什么。 請幫忙。
使用如何調試小程序(#1)和
print('C:/Users/Ratul/Downloads/Machine_Learning_Data/reddit_data/reddit_data/{}/RC_{}'.format(
timeframe.split('-')[0],timeframe))
而不是open
。 檢查是否全部存在-因為對於您的某些值而言, 它不存在 。 因此,錯誤。
如果大多數文件都存在,則處理錯誤本身要容易得多:
myname = 'C:/Users/Ratul/Downloads/Machine_Learning_Data/reddit_data/reddit_data/{}/RC_{}'.format(timeframe.split('-')[0],timeframe)
try:
with open(myname, buffering=1000) as f:
for row in f:
row_counter += 1
row = json.loads(row)
parent_id = row['parent_id']
body = format_data(row['body'])
created_utc = row['created_utc']
score = row['score']
comment_id = row['name']
subreddit = row['subreddit']
parent_data = find_parent(parent_id)
# maybe check for a child, if child, is our new score superior? If so, replace. If not...
if score >= 2:
existing_comment_score = find_existing_score(parent_id)
except FileNotFoundError as fnfError:
print(myname)
print(fnfError)
open()
命令並不關心您使用\\
或/
-如果使用\\
則應轉義它或使用原始字符串(aka: r'C:\\some\\dir\\file.txt'
)-您的語法可以正常使用'c:/somedir/file.txt'
()將在Windows下使用適當的目錄分隔符,即使您將其指定為'c:/somedir/file.txt'
