Question

好的，所以这段代码适用于在线课程，我觉得这个问题是由Notepad ++引起的，但我无法证明什么。

实际错误是： [Anaconda2] C:\Users\ia566\Desktop\Python>python countorgdb.py File "countorgdb.py", line 20 print pieces ^ IndentationError: unexpected indent

这是Notepad ++的图片：

注意文件树的更改方式。对代码的任何添加都会导致文件树中出现额外的分支，从而导致Indention Error。

完整代码：

import sqlite3

conn = sqlite3.connect('jbemaildb.sqlite')
cur = conn.cursor()

cur.execute('''
DROP TABLE IF EXISTS Counts''')

cur.execute('''
CREATE TABLE Counts (org TEXT, count INTEGER)''')

fname = raw_input('Enter file name: ')
if ( len(fname) < 1 ) : fname = 'mbox-short.txt'
fh = open(fname)
for line in fh:
    if not line.startswith('From: ') : continue
    pieces = line.split()
    org = pieces[1]
    print org
    # Here is were I a am trying to add a print statement and more code.
    cur.execute('SELECT count FROM Counts WHERE org = ? ', (org, ))
    row = cur.fetchone()
    if row is None:
        cur.execute('''INSERT INTO Counts (org, count) 
            VALUES ( ?, 1 )''', (org, ) )
    else : 
        cur.execute('UPDATE Counts SET count=count+1 WHERE org = ?', 
            (org, ))
    # This statement commits outstanding changes to disk each 
    # time through the loop - the program can be made faster 
    # by moving the commit so it runs only after the loop completes
    conn.commit()

# https://www.sqlite.org/lang_select.html
sqlstr = 'SELECT org, count FROM Counts ORDER BY count DESC LIMIT 10'

print
print "Counts:"
for row in cur.execute(sqlstr) :
    print str(row[0]), row[1]

cur.close()

我无法弄清楚我在做什么让Notepad ++如此愤怒。我只是希望能够添加到我的代码中。

如果未正确使用空格或制表符，则会出现缩进错误。您应该用四个空格缩进代码。试一试，看看它是否有帮助。
