[英]sqlite saving text file and output as it is : python
我正在尝试使用python将文本文件保存在sqlite中,但是当我尝试检索该文件时,看到换行符和其他字符。 有什么办法可以像原始文件一样输出文件? 有没有解决的办法。
import sqlite3
conn=sqlite3.connect('example.db')
c=conn.cursor()
c.execute("create table code_tag1 (language text, code BLOB, tag text)")
#c.execute("select * from sqlite_master")
with open("bubblesort_java.txt","rb") as f:
ablob=f.read()
c.execute("insert into code_tag1 values('java',?,'bubblesort')",[buffer(ablob)])
conn.commit()
row=c.execute("select * from code_tag1").fetchone()
print (repr(str(row[1])))
conn.close()
输出为:
'import java.util.Scanner;\r\n \r\nclass BubbleSort {\r\n public static void main(String []args)
{\r\n int n, c, d, swap;\r\n Scanner in = new Scanner(System.in);\r\n \r\n
System.out.println("Input number of integers to sort");\r\n n = in.nextInt();\r\n \r\n int
array[] = new int[n];\r\n \r\n System.out.println("Enter " + n + " integers");\r\n \r\n for
(c = 0; c < n; c++) \r\n array[c] = in.nextInt();\r\n \r\n for (c = 0; c < ( n - 1 );
c++) {\r\n for (d = 0; d < n - c - 1; d++) {\r\n if (array[d] > array[d+1]) /* For
descending order use < */\r\n {\r\n swap = array[d];\r\n array[d]
= array[d+1];\r\n array[d+1] = swap;\r\n }\r\n }\r\n }\r\n \r\n
System.out.println("Sorted list of numbers");\r\n \r\n for (c = 0; c < n; c++) \r\n
System.out.println(array[c]);\r\n }\r\n}'
如何获取原始文件中的代码?
谢谢

输出没有问题。 您正在打印字符串的repr
,这就是为什么它显示\\r
, \\n
等的原因。
>>> data = """Hello
... World"""
>>>
>>> print data
Hello
World
>>> print repr(data)
'Hello\nWorld'
>>>
