Rearranging elements in Python

[Nirmal]

Hey , i tried below

p = ['Eth1/1', 'Eth1/48','Eth2/1', 'Eth2/4','Eth101/1/1', 'Eth101/1/16', 'Eth101/1/3','Eth102/1/1', 'Eth102/1/2', 'Eth102/1/3','Eth103/1/1', 'Eth103/1/2', 'Eth103/1/3','Eth103/1/4','Eth104/1/1', 'Eth104/1/2', 'Eth104/1/3','Eth104/1/4']
with open("abc1.txt", "w+") as fw1, open("abc2.txt", "w+") as fw2:
    for element in p:
        if len(element.strip('Eth').split('/')[0]) == 1:    # if you have one digit before the first /
            fw1.write('int ' + i + '\n  mode\n')
           # write to abc1.txt
        else: # if you a sure that the input is correct else should work if you have three digits before /
            # write to abc2.txt   
            fw2.write('int ' + i + '\n  mode\n')

both the file abc1.txt and abc2.txt contains

int Eth104/1/4
  mode
int Eth104/1/4
  mode
int Eth104/1/4
  mode
int Eth104/1/4
  mode
