《Python核心编程》部分错误纠正(勘误表)(持续更新)

Chapter 3：

例3-1 makeTextFile.py

#!/usr/bin/env python
 
'makeTextFile.py'
import os
ls = os.linesep
 
#get File name
 
while True:
    fname = raw_input("Enter file name: ")
    if os.path.exists(fname):
        print "ERROR: '%s' already exists" % fname
    else:
        break
 
#get file contents lines
 
all = []
print "\nEnter lines('.' by itself to quit).\n"
 
#loop until user terminate input
 
while True:
    entry = raw_input('> ')
    if entry == '.':
        break
    else:
        all.append(entry)
 
#write lines to file with proper line-ending
fobj = open(fname,'w')
fobj.writelines(['%s%s' % (x,ls) for x in all])
#fobj.write('\n',join(all))
fobj.close()
print "DONE"

例3-2 readTextFile.py

#!/usr/bin/env python
 
'readTextFile.py'
#get filename
fname = raw_input('Enter filename: ')
print
 
#attempt to open file for reading
try:
    fobj = open(fname,'r')
except IOError, e:
    print "*** file open error:", e
else:
    #display contents to the screen
    for eachLine in fobj:
        print eachLine,
 
fobj.close()
