I want to convert a list into range.

a = ['Eth1/1', 'Eth1/2', 'Eth1/3', 'Eth1/4', 'Eth1/5', 'Eth1/6', 'Eth1/7', 'Eth1/8', 'Eth1/9', 'Eth1/10','Eth2/1', 'Eth2/2', 'Eth2/3', 'Eth2/4', 'Eth2/5', 'Eth2/6','Eth3/1', 'Eth3/2', 'Eth3/3', 'Eth3/4', 'Eth3/5', 'Eth3/6','Eth4/1', 'Eth4/2', 'Eth4/3', 'Eth4/4', 'Eth4/5', 'Eth4/6']

what i am trying :

fp = open('mode.txt' , 'w+')
for i in a: 
 fp.write('confi ' + i + 'n mode n')

what i am looking for :

confi Eth1/1-5
 mode
confi Eth1/6-10
 mode
confi Eth2/1-6
 mode
confi Eth3/1-6
 mode
confi Eth4/1-6
 mode

Any idea how to do this ?

You could create a loop that checks the current element as the start. If it starts with Eth1 then get the 4th element after as the end. Otherwise, keep the starting Eth_, iterate through the list until you get the last Eth_ element or until the list end. Assign the last element as the end.

a = ['Eth1/1', 'Eth1/2', 'Eth1/3', 'Eth1/4', 'Eth1/5', 'Eth1/6', 'Eth1/7', 'Eth1/8', 'Eth1/9', 'Eth1/10','Eth2/1', 'Eth2/2', 'Eth2/3', 'Eth2/4', 'Eth2/5', 'Eth2/6','Eth3/1', 'Eth3/2', 'Eth3/3', 'Eth3/4', 'Eth3/5', 'Eth3/6','Eth4/1', 'Eth4/2', 'Eth4/3', 'Eth4/4', 'Eth4/5', 'Eth4/6']
i = 0

while i < len(a):
 start = a[i].split('/')
 if (start[0] == 'Eth1'):
 i += 5
 else:
 key = start[0]
 i += 1
 while i < len(a) and a[i].split('/')[0] == key:
 i += 1
 end = a[i-1].split('/')
 print('confi ' + start[0] + '/' + start[1] + '-' + end[1] + 'n moden')
