Python list in list with 2 strings

I have 2 lists of strings. I would like to combine them together to create list in lists like this one below. [['Hello','praet:sg:m1:perf'], ['world', 'subst:pl:acc:n']] How to do it? Somehow create instance of list in list or there is some "python magic"?

Thank you

zip (Python Docs) is what you are looking for. You can stitch together two lists in a list comprehension:

l1 = ['Hello', 'world']
l2 = ['praet:sg:m1:perf','subst:pl:acc:n']

zipped = [list(items) for items in zip(l1,l2)]

print(zipped)

Result:

[['Hello', 'praet:sg:m1:perf'], ['world', 'subst:pl:acc:n']]

There are many ways to do that.

ex-1: by using '+' 

list1=['Hello', 'world'] 
list2 = ['praet:sg:m1:perf','subst:pl:acc:n']

print([list1]+[list2])

ex-2: by using append()

res =[]
list1=['Hello', 'world'] 
list2 = ['praet:sg:m1:perf','subst:pl:acc:n']

res.append(list1)
res.append(list2)
print(res)

ex-3: by using zip()

list1=['Hello', 'world']
list2 = ['praet:sg:m1:perf','subst:pl:acc:n']

res = [[l1, l2] for l1,l2 in zip(list1, list2)]

print(res)

Use zip

list1=['Hello', 'world']
list2 = ['praet:sg:m1:perf','subst:pl:acc:n']

result = [[x, y] for x,y in zip(list1, list2)]

print(result)

Output:

[['Hello', 'praet:sg:m1:perf'], ['world', 'subst:pl:acc:n']]

Just add the two list you have to another list: 

list1 = ['Hello', 'praet:sg:m1:perf']
list2 = ['world', 'subst:pl:acc:n']

result = [list1, list2]

Another way:

result = []
list1 = ['Hello', 'praet:sg:m1:perf']
list2 = ['world', 'subst:pl:acc:n']

...

result.append(list1)
result.append(list2)

I hope this helps:

list1=['Hello', 'world']
list2 = ['praet:sg:m1:perf','subst:pl:acc:n']

newlist = []

for i in range(len(list1)):
   newlist.append([list1[i],list2[i]])
