ok so, I want to have the bottom code to search that txt file find the line that contains the search criteria and then delete the line that contains the search criteria.



Ideas?


Code: 
if action2=='2':
		fob=open('/Users/NSutton/Simple Adress/bookdata.txt','r')
		searchdelete=raw_input("Enter the name of the contact you'd like to delete: ")
		for line in fob:
			if searchdelete in line:
    				print line

Instead of printing any line containing the search criteria, copy (append) any line that does not contain the search criteria to a destination file, or to memory. Essentially, you want to copy your source file line by line to a destination file, but skip any line where you find a match. If you want it to replace your source file, make the destination file a temp file, and when done, delete the source file and rename the temp file to the source file's name.

I understand in concept but am lost in actually putting that to code....
