You should really use lists instead of a long string making the IP_Addresses variable:

IP_Addresses = ["1.1.1.1","2.2.2.2","3.3.3.3"]

Then you won't need to split the input.

If you insist on using a long string, then use .split("\n") to split on new lines instead of .

Example:

for number, IP_Address in enumerate(IP_Addresses.split("\n")):
    print(number, IP_Address)

How do I remove extra lines `0` and `4` in the output? – Apr 20 '20 at 08:52
These are added by the first and final blank lines in you strings, please check my new answer for a guide on how to use a list instead. – Søren Eriksen Apr 20 '20 at 08:54

You don't need the split function when you're using a list. – Søren Eriksen Apr 20 '20 at 08:58

You could split the variable by newline, like so:

IP_Addresses = '''
... 1.1.1.1
... 2.2.2.2
... 3.3.3.3
... '''

i = 0
IP_Addresses = IP_Addresses.split('\n')
for line in IP_Addresses:
    if line and any(char.isdigit() for char in line):
        i += 1
        print(f'{i} - {line}')

Output:

1 - ... 1.1.1.1
2 - ... 2.2.2.2
3 - ... 3.3.3.3
