    <p>I'm sorry if this question is a bit basic, or if I've missed an answer elsewhere, but please take pity on a lost and confused beginner and give me a hand if you can. I've got a load of long files consisting of lines of 'date time id number random crap' and I'm trying to count the amount of times certain numbers occur alongside certain ids. As far as I can tell, everything is right except I only get one number returned, rather than hundreds. I've really cut this down to just the bits that might be going wrong. There are probably hundreds of quicker and easier ways to do what I'm trying to do, but I don't know them yet. Please do let me know! I have a list of the data from the file, called data, and a list of the ids present in the file. </p> <pre><code>#get date(data[i][0]), time(data[i][1]), number(data[i][3]), id(data[i][4]) from original data if a certain id (found in listofids) is present, and write into new list data0=[] data1=[] etc values=[data[i][0], data[i][1], data[i][3], data[i][4]] for line in data: if listofids[0] in line: data0.append(values) if listofids[1] in line: data1.append(values) etc #put number into list h if it occurs in list data0 h=[] r=range (0, len(data0)) for i in r: number=data0[i][3] if number not in h: h.append(number) print (len(h)) print (h) #count the time each element in list h occurs in list data0 print (data0.count(h[0]), data0.count(h[1]), data0.count(h[2])) </code></pre> <p>I'm sorry if this is a bit messy and confusing, and I'm especially sorry if I'm missing something really easy.</p> <p>Thank you for helping!</p>

    1. COAnd how would such a line look like? Do they have a fixed format, such as no spaces in the IDs?

    3. COThey're all '07/11/2008 09:00:06 word #0F 0006E7895B word word' in the original file, although I've cut out the words to leave just '07/11/2008 9:00:06 #0F 0006E7895B'. Obviously the dates, times, ids and numbers vary on each line

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
