convert list to string using python reduce()

Question

I am trying to convert the list of input words ['hdjk', 'salsap', 'sherpa'] to output: 'hdjk salsap sherpa' using the reduce()

Here is the code I am trying to work on:

from functools import reduce
input_list =  ['hdjk', 'salsap', 'sherpa']
list(reduce(lambda x,y: x+" "+y, input_list)) # This gives irrelevant output

I have also tried this:

xinpl = [x.split() for x in input_list]
list(reduce(lambda x,y: x+" "+y, xinpl))

This code joins all the elements in the input_list and it works for me

print(" ".join(input_list))

I looked at other similar threads and been trying this a lot: Make List to String Python

I am still a learner. Gurus can your please help?

@coldspeed, Since I am still a learner I was exploring and trying other ways of achieving the same output through different ways. — IndPythCoder

The reduce part of the code is working just fine. The only problem is that it is returning a string, which is then converted to a list. Simply remove the list in list(reduce(...)) and it works as expected.

>>> from functools import reduce
>>> input_list =  ['hdjk', 'salsap', 'sherpa']
>>> reduce(lambda x,y: x+" "+y, input_list)
'hdjk salsap sherpa'

input_list = ['All','you','have','to','fear','is','fear','itself']

from functools import reduce

string1 = str(reduce(lambda x,y: x + " " +y, input_list))

print(string1)
