错误蟒蛇IO错误：没有这样的文件或目录

Question

当我尝试运行模块在Python打开文件用下面的代码：

from sys import argv 

script,filename = argv 

txt = open(filename) 

print "Here's your file %r:" % (filename) 
print txt.read() 

print "Type the filename again:" 
file_again = raw_input(">") 

txt_again =open(file_again) 

print txt_again.read() 

使我有以下错误：

IOError: [Errno 2] No such file or directory: 'ex15_sample.txt' 

Answer 1

可能文件ex15_sample.txt不在当前执行目录中吗？您是否尝试在raw_input步骤编写文件的完整路径，即/tmp/ex15_sample.txt？
