Print a string which has the reverse order

Question

Assignment:

Print a string which has the reverse order
'Python love We. Science Data love We'

I tried this:

strg = We love Data Science. We love Python
words = strg.split(" ") 
words.reverse()
new_strg = " ".join(words)
print(new_strg)

>>> Python love We Science. Data love We

But the answer isn't as expected because the . after Science is not at the proper place.

How to get the expected result?

Answer 1

Is this the output you need?

Python love We. Science Data love We

Then the code is

strg = 'We love Data Science. We love Python'
pos = len(strg) - strg.index('.') - 2
words = [e.strip('.') for e in strg.split()]
words.reverse()
new_strg = ' '.join(words)
print(new_strg[:pos] + '.' + new_strg[pos:])

Or another way to do it:

strg = 'We love Data Science. We love Python'
new_strg = [s.split()[::-1] for s in strg.split('.')][::-1]
print(' '.join(new_strg[0]) + '. ' + ' '.join(new_strg[1]))
#or
print('{}. {}'.format(' '.join(new_strg[0]), ' '.join(new_strg[1])))

Or to raise the bar:

strg = 'We love Data Science. We love Python'
print('. '.join([' '.join(new_strg.split()[::-1]) for new_strg in strg.split('.')[::-1]]))
