Get a list (without nested list) directly from a list comprehension [duplicate]
This question already has an answer here:
Interleave multiple lists of the same length in Python
7 answers
I want to return a list with the interleaved elements of two lists directly from the list comprehension - without use a next step to flaten the result. Is it possible?
alist1_temp=[1, 4,2]
alist2_temp=[3, 7,4]
t=[[x,y] for x,y in zip(alist1_temp, alist2_temp)]
Return [[1, 3], [4, 7],[2, 4]]
But how can I get directly from the list-comprehension [1, 3, 4, 7, 2, 4]?

Try this with just zip to get it in that order that you want:
[i for j in zip(alist1_temp, alist2_temp) for i in j]
if you don't mind the order just do:
alist1_temp + alist2_temp
or get it with itertools.chain thanks to @buran:
import itertools
list(itertools.chain(alist1_temp, alist2_temp))

with the chain - why not justlist(itertools.chain(alist1_temp, alist2_temp))? it's not comprehension, but I am not sure comprehension is strict requirement. And anyway the order of elements in the result is different.

print(t) #prints [1, 3, 4, 7, 2, 4]

np.vstack((alist1_temp,alist2_temp)).flatten('F')
or you can flatten your list comprehension as well

As you specified that you want get it from from the list-comprehension:
alist1_temp=[1,4,2]
alist2_temp=[3,7,4]
L = len(alist1_temp)+len(alist2_temp)
t = [alist2_temp[i//2] if i%2 else alist1_temp[i//2] for i in range(L)]
print(t) #prints [1, 3, 4, 7, 2, 4]
