    replied to How to delete lines between two words from text file?
    in Python
    i figured it out. the following code, does what i need to do.

    Code:
    orig_file = open (input(), "r")
lines = orig_file.readlines()
 
start = False
saved_list = []
for rec in lines:
    if "count" in rec:
        start = True
    if "Volume" in rec:
        start= False
    if not start:
        saved_list.append(rec) 
 
new_text_file
    ...

        How to delete lines between two words from text file?

        Hi,

        i need a script, that deletes all the lines between two certain words in a text file. the two words appear several times in the text file.

        i have a code, that works so far. the problem is, once it looped for the first time through the text file, the end_word appears before the new start_word. so i have to tell the program, to start searching for the end_word, after the start_word.

        here is the code....

            in Python
            well, i do have the full list.
            i want to loop through the list.

            i make up an example. i want to do something with all the green fruits in there:

            Code:
            fruit_list = ['greenapples', 'blueapples', 'greenpears', 'bluepears', 'greenoranges', 'blueoranges']

for green* in fruit_list:
            but it does not work, because i need to loop for the full value like greenapples.
            and i am looking for a way to...

              well i can not traverse the list, because i just know parts of the value. in order to traverse, you need to have the exact list element value, right?

              so i need a different way. any suggestions?

                okay thanks bvdet. my problem is, that i just know parts of my list element, for which i am looping.

                so i tried to work my way around it, with this code:
                Code:
                orig_file = open ("*Strata1CombinedAll.txt", "r")
lines = orig_file.readlines()




import fnmatch
def find(seq, pattern):
    pattern = pattern.lower()
    for i, n in enumerate(seq):
        if fnmatch.fnmatch(n.lower(),
                ...

                  hi,

                  i am trying to get this to work. it works fine so far. only when i try to loop through the list, i get an error.
