Hi I am new to both Python and this forum.
My question:
I have two lists:
list_a = ['john','peter','paul']
list_b = [ 'walker','smith','anderson']
I succeeded in creating a list like this using zip:
list_c = zip(list_a, list_b)
print list_c
# [ 'john','walker','peter','smith','paul','anderson']
But the result I am looking for is a list like:
list_d = ['john walker','peter smith','paul anderson']
Whatever I tried I didn't succeed! How may I get this result?
You are getting zipped names from both the lists, simply join each pair, like this
print map(" ".join, zip(list_a, list_b))
# ['john walker', 'peter smith', 'paul anderson']
List_C = ['{} {}'.format(x,y) for x,y in zip(List_A,List_B)]
If list_a and list_b has same length always then try it:
list_c = [list_a[i]+' '+list_b[i] for i in xrange(0,len(list_a))]
On the other hand if list_a and list_b may have different lengths then:
list_c=[]
for i in xrange(0,len(list_a) if len(list_a)>len(list_b) else len(list_b)):
merged_item = (list_a[i] if i<len(list_a) else '')+\
(' ' if i<len(list_a) and i<len(list_b) else '')+\
(list_b[i] if i<len(list_b) else '')
list_c.append(merged_item)
One way to solve this problem is as below:
list_d = [] # desired output list
list_a = ['john', 'peter', 'paul']
list_b = ['walker', 'smith', 'anderson']
for i in range(len(list_a if len(list_a) < len(list_b) else list_b)):
f = " ".join([list_a[i], list_b[i]])
list_d.append(f)
print d
The output you will get on executing the above code is:
['john walker', 'peter smith', 'paul anderson']
