loop over a list and its sub-strings seperated by comma

Can someone help me with below. I have a list like below.

list = ['INDIA,CHINA,JAPAN','FRANCE,IRELAND,ENGLAND']

I am trying to convert above list into below.

newlist = ['INDIA','CHINA','JAPAN','FRANCE','IRELAND','ENGLAND']

I have tried split() which is not working.

newlist = list.split(',')

Thanks much for your help.

You can use a List Comprehension to achieve this easily

list = ['INDIA,CHINA,JAPAN','FRANCE,IRELAND,ENGLAND']
print([word for string in list for word in string.split(',')])

Output

['INDIA', 'CHINA', 'JAPAN', 'FRANCE', 'IRELAND', 'ENGLAND']

list = ['INDIA,CHINA,JAPAN','FRANCE,IRELAND,ENGLAND']
newlist = []
for item in list:
    newlist.extend(item.split(','))
print(newlist)

This will produce:

['INDIA', 'CHINA', 'JAPAN', 'FRANCE', 'IRELAND', 'ENGLAND']

It is never a good idea to name your variables same as python keywords or builtin methods. Try naming it something different. For this problem you do not need any explicit for loops, there are suitable list methods to do this for you:

list_ = ['INDIA,CHINA,JAPAN','FRANCE,IRELAND,ENGLAND']
newlist = ','.join(list_).split(',')

#Output:
['INDIA', 'CHINA', 'JAPAN', 'FRANCE', 'IRELAND', 'ENGLAND']

You should use split with the strings in the list, not the list:

L = ['INDIA,CHINA,JAPAN', 'FRANCE,IRELAND,ENGLAND']
new_L = [x for s in L for x in s.split(',')]
print(new_L)

Output:

['INDIA', 'CHINA', 'JAPAN', 'FRANCE', 'IRELAND', 'ENGLAND']

try this : 

list = ['INDIA,CHINA,JAPAN','FRANCE,IRELAND,ENGLAND']

result = []

for i in list : 
  s = i.split(",") 
  for j in s : 
      result.append(j)

print(result)

output : 

['INDIA', 'CHINA', 'JAPAN', 'FRANCE', 'IRELAND', 'ENGLAND']

Try this :

list_ = ['INDIA,CHINA,JAPAN','FRANCE,IRELAND,ENGLAND']
newlist = []
for i in list_:
   newlist += i.split(',')

Output :

['INDIA', 'CHINA', 'JAPAN', 'FRANCE', 'IRELAND', 'ENGLAND']
