How to make a language dictionary in python?

[hoolaboola]

I want the user to be able to insert a word in english and have it returned in spanish.
This is what I have:

# Two arrays, one for english words, the other for their spanish hit.
english = [ ]
spanish = [ ]

# The words and definitions are in a file. English word first then tab and then Spanish definition on one line. Then add the words in their respective arrays.

file=open("eng-span.txt", "r")

while True :
# Read one line

    line = file.readline()

    # Check, if it's the last line

    if line == "" :
        break

    word_pair = line.split ("\t")
    english.append (word_pair[0])
    spanish.append (word_pair[1])

print " Enter the English word for which you want the Spanish definition to: "
word = raw_input()

# Tricky part for me: a for-cycle that checks whether the inserted word exists in the array 'english' and then prints the corresponding Spanish definition from array 'spanish'. I have the cycle all wrong...

for i in english:
    if word in english :
        print spanish[ i ]
    else :
        print "No definition"

Please at least test your code before posting. The "while True" is infinite because this line will never test as True

    # Check, if it's the last line
    if line == "" :     ## still contains newline so is "\n"
        break 
#
#     instead, use this
for rec in open("eng-span.txt", "r"):

To find something in a list, you can use index

el_number = english.index(word)

Why not use the built in dictionary structure for this?

Something like this:

d=dict()
#create language dictionary
for line in open('eng-span.txt'):
    temp=line.split('\t')
    d[temp[0]]=temp[1].strip()

e=raw_input("Enter english word for translation: ")
try:
    print "Spanish is: ", d[e]
except:
    Print "No translation found"
