How about a version that uses Python 3.0 string formatting:
field_widths = [14, 6, 18, 21, 21, 4, 6]
out = open(r"c:\temp\output.csv", 'w')
for line in open(r"c:\temp\input.csv", "r"):
fields = line.rstrip().split('|')
outline = ""
for pair in zip(fields, field_widths):
outline += "{0:{1}}".format(*pair)
out.write(outline + "\n")
out.close()
Or, if you hate NLs (and, perhaps, like obfuscation):
field_widths = [14, 6, 18, 21, 21, 4, 6]
out = open(r"c:\temp\output.csv", 'w')
for line in open(r"c:\temp\input.csv", "r"):
fields = line.rstrip().split('|')
out.write("".join(["{0:{1}}".format(*pair) for pair in \
zip(fields, field_widths)]) + "\n")
out.close()
