Question

Below is my code i am reading.txt file then making a list and then saving it to excel but in excel i am getting ('ip subnet/mask', ) but i want only (ip subnet/mask) in out put Below are my code blocks 1.I read routing Table output from Txt file and create a list 2.then from 10.0.0.0/8 address space i remove routing table sybnets 3.I save the available IP,s to Available.txt file 4.Create List from Available.txt file 5.then i create excel file and then i save the list out put to excel in specific 10.xxx/16 sheet

Answer 1

I have used re.sub function to remove characters from string

def ip_adresses1(): lst = [] for line in fstring_2: for word in line.split(): word = re.sub("IPSet", " ", word) word = re.sub(",", " ", word) word = re.sub("'", " ", word) word = re.sub("(", " ", word) word = re.sub(")", " ", word) word = re.sub("]", " ", word) word = re.sub("[", " ", word) result = pattern.search(word) if result: lst.append(word) return lst
