python [Errno 2] No such file or directory:

Question

I learn python on Ubuntu system. There were errors shen I tried to read a file .

fw = open(outfile,"a") 
outfile = 'sougou/Reduced/C000008_pre.txt'
IOError: [Errno 2] No such file or directory: 'sougou/Reduced/C000008_pre.txt'

• anthony sottile: Either "sougou" does not exist or "sougou/Reduced" does not exist
• Andrew Guy: Where are you calling Python script from? Or is this in an interactive terminal?

Answer 1

Without any additional information, I can see two possibilities here.

1. The file you are trying to access doesn't exist.

2. The path to the file is not correct relative to the location you are calling your Python script from.

Try providing the absolute path to the file, and see if that fixes your issue:

outfile = '/some/path/here/sougou/Reduced/C000008_pre.txt'

Answer 2

1. Maybe file sougou/Reduced/C000008_pre.txt does not exist
2. The script does not be put in directory which contains sougou directory
3. You should close file after open: fw.close() or using with open(outfile,"a") as fw: is better
