我在敲《笨办法学python》这本书时遇到的问题，习题16。
我的代码如下：
1
445from sys import argv
script, filename = argv
print "We're going to rease %r." % filename
print "If you don't want that, hit CTRL-C (^C)."
print "If you do want that, hit RETURN."
raw_input("?")
print "Opening the file..."
target = open(filename, 'w+')
print "Trincating the file. Goodbye!"
target.truncate()
print "Now I'm going to ask you for three lines."
line1 = raw_input("line 1: ")
line2 = raw_input("line 2: ")
line3 = raw_input("line 3: ")
print "I'm going to write these to the file."
target.write(line1)
target.write("\n")
target.write(line2)
target.write("\n")
target.write(line3)
target.write("\n")
print "Here's your file %r:" % filename
print target.read()
print "And finally, we close it."
target.close()
结果如下：
我就想在写完文件后，再看下文件的内容。
但是并没有读取新文件，还出现了奇怪的东西。
请问我的代码问题出现在哪了？
