I got this error on sentence=input("Enter the sentence"):

Traceback (most recent call last):

Are you using Python 2 or 3? If you're using Python 2, you should use `raw_input()` — Barmar, Mar 05 '18 at 21:05
@Barmar: Given the `print` at the end has parentheses, I'm guessing it's intended to be Python 3. Can't be certain, though. — Fred Larson, Mar 05 '18 at 21:06
codio@domino-basic:~/workspace$ python Lab3.py Enter the sentence: have a nice day Traceback (most recent call last): File "Lab3.py", line 3, in sentence = input("Enter the sentence: ") File "", line 1 have a nice day ^ SyntaxError: invalid syntax — ruby, Mar 05 '18 at 21:13
You should have used [edit] to add it into the question. Now someone else tried – and it's a different error! — Jongware, Mar 05 '18 at 21:15
we're using Cordio on the class so what i need to do to correct this program on cordio? — ruby, Mar 06 '18 at 00:52

This error is caused by executing Python 3 code with Python 2.

If you want to use Python 3

Your program works fine for me when executed with Python 3. Just use the python3 command to run it:

python3 you_code.py

If you want to use Python 2

Remove print()'s parenthesis: if sentence == "have a nice day":
Replace input() by raw_input(): sentence = raw_input("Enter the sentence: ")

Which gives this Python 2 program:

import random

sentence = raw_input("Enter the sentence: ")
sentence=sentence.lower()
languages=[['hello','goodbye','thank you',"you\'re welcome",'have','a','nice','day','how','are','you'],
               ['ola','Tehau','obrigado','seja bem-vindo','ter','uma','bom','dia','como','esta','voce'],
               ['hello','faida','Asante','karibu','kuwa na','a','nzuri','siku','vipi','ni','wewe'],
               ['hallo','Vaarwel','dank je','graag gedaan','habben','een','leuk','dag','hoe','ziin','u'],
               ['hola','adios','gracias','De nada','tener','un','bonito','dia','como','son','tu']]
t=''

if sentence == "have a nice day":
    words=sentence.split()
    for word in words:
        i=languages[0].index(word)
        r=random.randint(1,4)
        t+=languages[r][i]+' '
elif sentence == "goodbye":
    i=languages[0].index(sentence)  
    r=random.randint(1,4)   
    t+=languages[r][i]
elif sentence == "hello":
    i=languages[0].index(sentence)
    r=random.randint(1,4)  
    t+=languages[r][i]
elif sentence == "you're welcome":
    i=languages[0].index(sentence) 
    r=random.randint(1,4)
    t+=languages[r][i]
elif sentence== "thank you":
    i=languages[0].index(sentence)
    r=random.randint(1,4)
    t+=languages[r][i]
elif sentence== "how are you":
    words=sentence.split()
    for word in words:
        i=languages[0].index(word)
        r=random.randint(1,4)
        t+=languages[r][i]+' '

print "The translated sentence is", t
