seqfile 0.0.1

Usage

If you want to create sequential files to write output to (say from different threads or from consecutive runs of the same program), then you can use this module.

# Assume files "./a.0.txt" and "./a.3.txt" exist.
>> import seqfile

# Providing prefix and suffix finds the next file in the sequence
# ignoring any gaps
>> seqfile.findNextFile('.', prefix='a.', suffix='.txt')
'./a.4.txt'

# Providing a file name generator as fnameGen produces the first file
# which it was successful in creating.
>> seqfile.findNextFile('.', fnameGen=lambda x: 'a.' + str(x) + '.txt')
'./a.1.txt'

The returned file will exist, be empty, and can be opened for writing.
