My code is not very good but this is a really interesting problem. When looking for a forward slash in a string all are found except for if the forward slash is in the last word in the file. Here is my code.
#!/usr/bin/python
import sys
if len(sys.argv)!=2:
print "usage: %s filename\n" % (sys.argv[0]);
exit(0);
f = open(sys.argv[1]);
lines = [i for i in f.readlines()]
finals = [];
for line in lines:
words = line.split(",");
for word in words:
if word.find("/") != -1:
datefixes = word.split("/")
if datefixes[2].__len__() == 4:
temp = datefixes[2]
word = datefixes[0] + "-" + datefixes[1] + "-" + temp[-2:]
finals += "," + word;
tempstring = ''.join(finals)
finallist = tempstring.split("\r\n")
finalstring = ""
for tmpstrpart in finallist:
if tmpstrpart != "" or tmpstrpart !="\r\n":
finalstring += tmpstrpart[1:] + "\r\n"
print finalstring
and here is a sample input
ACPVBF,1930-729,Z729,12/16/2014,6/10/2008,1/5/2003,44-48-46,39-43-41,35-39-37,29-33-31

in the code these lines are split by commas. if the word at the end contains a / the forward slash is not found. but only if it is at the end. the rest work fine.
edit: The output I am currently getting on these lines is:
ACPVBF,1930-729,Z729,12-16-14,6-10-08,1-5-03,44-48-46,39-43-41,35-39-37,29-33-31

the output that I am trying to get from these lines is:
ACPVBF,1930-729,Z729,12-16-14,6-10-08,1-5-03,44-48-46,39-43-41,35-39-37,29-33-31

I want the one with the brackets around it to change also.
final working code based on BrenBarn’s answer:
#!/usr/bin/python
import sys
import re
if len(sys.argv)!=2:
print "usage: %s filename\n" % (sys.argv[0]);
exit(0);
f = open(sys.argv[1]);
x = f.read()
f.close()
filename = sys.argv[1]
filename = filename[:-4] + " finished.csv"
f = open(filename, 'w')
f.write(re.sub(r'(\d{1,2})/(\d{1,2})/\d{2}(\d{2})', r'\1-\2-\3', x))
f.close()
Thanks for all the help. Sorry I can’t upvote yet.
I’m not sure what the problem is, but I think what you’re trying to do can be accomplished way more easily by just using a regular expression.
