python - Confusion about string find? -


I have a list of data that I want to find.

Name, address the age of the family members of the Doubt etc.

I want to search through the lines of data so that I can stop searching, 'but after the name to customize the search appears. I believe I want to use this command: 

  str.find (sub [, start [, end]])

I'm having trouble writing the code in this structure though. What tips do you make for string to work?

Here are some sample data: 

  Bennett, John, 17054099 "," 5 "," 156323558 "," - "," 0 ", 714 // Menendez "Juan, 7730126", "5", "158662525" 11844 // Brown, Jamal, "9", "2296, 92", "+", "0", "4432 //  / Pre> 
 The idea is that I want to search my program only for "," and do not want to search through the remaining big lines. 
 
 Edit. So this is my code . 
 
 I just want to find the lines from the first comma in PurataSatet. It is confused about how to implement the existing code. 
 For the line in the full set, 
  counter = 1: print counter counter + = 1 for matching t: If line in t : Smalldataset.write (line)

If I understand your glasses correctly For fasting in the list: firstcomma = thestring.find (',') Havename = thestring.fin D (name, 0, first column) if havename> = 0: print "Found name:", dostring [: first conma] Edit : Edit the OP Q, this will be something like this: 

  Counter = 1 for line in full set : Print Counter Counter + = 1 firstcomma = thestring.find (',') havename = thestring.find (T, 0, the first conma) if the hayendam & gt; = 0: smalldataset.write (line)

Of course, using the counter is unpredictably low-level, and will be a better eqv

< For pre-> counter, line in enumerate (fullsets): print counter + 1 first comma = thestring.find (',') havename = thestring.find (T, 0, first column) if havename & gt; = 0: smalldataset.write (line)

But this does not affect the question as asked.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
