I have a list containing some tuples as well as normal strings like below : 

a = ['sore', ('PHENOMENA', 'sore'), 'throat', ('ANATOMY', 'throat'), 'and',   'leg', ('ANATOMY', 'leg')]

I want to write it in a space separated text file in a format like:

sore ('PHENOMENA', 'sore') throat ('ANATOMY', 'throat') and leg ('ANATOMY', 'leg')

Something like this?

>>> ' '.join(map(str, a))
"sore ('PHENOMENA', 'sore') throat ('ANATOMY', 'throat') and leg ('ANATOMY', 'leg')"

map(str, a) convert all elements in a to string object, then ' '.join() join them by space and returns a string object.

You can also use a list comprehension instead of map():

>>> ' '.join(str(i) for i in a)
"sore ('PHENOMENA', 'sore') throat ('ANATOMY', 'throat') and leg ('ANATOMY', 'leg')"

Try this

a = ['sore', ('PHENOMENA', 'sore'), 'throat', ('ANATOMY', 'throat'), 'and',   'leg', ('ANATOMY', 'leg')]
s = ' '.join(str(part) for part in a)    
with open('outfile.txt', 'w') as outfile:
    outfile.write(s)

In the directory where you run this code you will get a file named 'outfile.txt' containing this:

sore ('PHENOMENA', 'sore') throat ('ANATOMY', 'throat') and leg ('ANATOMY', 'leg')

You can join each element of the list by a space via ' '.join(). The caveat is you need to convert everything to string, including the tuples, which you can do using map.

One possible way of coding is as simple as:

with open('file.txt', 'w') as f:
    f.write(' '.join(map(str, a)))
