python-2.7 - python IOError中的错误：没有这样的文件或目录

Question

当我尝试使用以下代码运行模块以在 python 中打开文件时：

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()

给我以下错误：

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

Answer 1

可能该文件ex15_sample.txt不在当前执行目录中？您是否尝试在raw_input步骤中写入文件的完整路径，即/tmp/ex15_sample.txt？
