str.replace doesn't change the original string, it returns a new one; strings are immutable in Python. Also, you don't actually change the original list of strings x, so you can't get the complete sentence. Try using enumerate:

for i, s in enumerate(x):
    if s.endswith("ئ") and len(s) == 3:
        x[i] = s.replace("ئ","ء")
    if s.endswith("ىء") and len(s) >= 5:
        x[i] = s.replace("ىء","ئ")

Now the whole sentence is in x:

print(' '.join(x))

This allows you to define multiple replacements that could apply to the same word, but lets you print the whole modified sentence at the end.

The information in this answer is true, but I don't think it actually explains the problem. – user2357112 Apr 18 '14 at 14:48

for s in x:
  if s.endswith("ئ") and len(s)==3 :
    print(s.replace("ئ","ء"))
  if s.endswith("ىء") and len(s)>=5:
    print(s.replace("ىء","ئ"))

It looks like you're splitting the string into words and performing replacements on each word based on specific criteria. However, if there isn't a replacement defined for a word, you never print it. You need a case for the words where you don't replace any characters:

for s in x:
  if s.endswith("ئ") and len(s)==3 :
    print(s.replace("ئ","ء"))
  elif s.endswith("ىء") and len(s)>=5:
    print(s.replace("ىء","ئ"))
  else:
    print(s)

If you want to put all the output on one line, you can build a list of processed words, re-join them with spaces, and print the result:

l = []
for s in x:
  if s.endswith("ئ") and len(s)==3 :
    l.append(s.replace("ئ","ء"))
  elif s.endswith("ىء") and len(s)>=5:
    l.append(s.replace("ىء","ئ"))
  else:
    l.append(s)
print(' '.join(l))
