Python 如何修复IOError:[Errno 2]没有此类文件或目录错误？

我收到一个IOError:[Errno 2]没有这样的文件或目录错误，我似乎无法找出问题所在。我已经检查了目录，文件已经存在。 此外，我正试图通过许多文本文件运行这个程序，所以如果你能检查一下，看看是否有任何其他问题，这将是伟大的

下面是具体的错误：

Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line   325, in RunScript
exec codeObject in __main__.__dict__
File "H:\Python scripts\Script1.py", line 45, in <module>
CsvTrack = open(file_name2, "r")

回溯（最近一次呼叫最后一次）：
RunScript中的文件“C:\Python27\Lib\site packages\pythonwin\framework\scriptutils.py”，第325行
主目录中的exec codeObject__
文件“H:\Python scripts\Script1.py”，第45行，在
CsvTrack=打开（文件名2，“r”）

IOError:[Errno 2]没有这样的文件或目录：u'20060705t2.csv'

创建文件时，需要在每个文件的路径前加上前缀：

input = open(os.path.join(env.workspace, filename), 'r')

创建文件时，需要预先指定每个文件的路径：

input = open(os.path.join(env.workspace, filename), 'r')
