Translating language in python - Liquid_Ocelot - Apr-01-2017
Hey everyone.
I am struggling to get my head around nested if statements particularly with a program I am needing to write which requires me to use nested if-statements (not lists) in order to write a function that finds and prints the translation of either cat or dog from English into German, French or Spanish.
My code is looking like it is in the complete wrong direction
word = ''
french = ''
print ("What do you want to translate to")
word = input()
while input != french:
print ("Enter a word in french")
break
while input == french:
print ("Try again")
while word != 'dog':
print ('Invalid')
word = input()
while word == 'dog':
print("chien")
breakand the output What do you want to translate to french Enter a word in french Invalid dog chien Process finished with exit code 0

You do not need to initialize anything in you are just looking for a simple translation. And if all you want is IF-statements. This is a quick one:
language = raw_input("What do you want to translate to :")
words = raw_input("Please state the word :")
if language == "French":
if words == "chien":
print("English => Dog")
print("Dutch => hond")
elif words == "chat":
print("English => Cat")
print("Dutch => kat")
else:
print("I can not understand")
# KEEP ADDING ELIF FOR ALL THE OTHER WORDS
if language == "English":
if words == "dog":
print("French => chien")
print("Dutch => hond")
elif words == "cat":
print("French => chat")
print("Dutch => kat")
# KEEP ADDING ELIF FOR ALL THE OTHER WORDS
else:
print("I can not understand")If you want to go extreme you can add more if statements in case the user enters something wrong and/or enters a language that is not supported.

That gives me a basis to work on thanks heaps.

Well, I would use a different approach.
french = {"chien": ("English => Dog", "Dutch => hond"),
"chat": ("English => Cat", "Dutch => kat")}
english = {"dog": ("French => chien", "Dutch => hond"),
"cat": ("French => chat", "Dutch => kat")}
lang = input("Translate to - English/French: ")
word = input("Write a word: ")
if lang.lower() == french and word in french:
for trans in french[word]:
print(trans)
elif lang.lower() == english and word in english:
for trans in english[word]:
print(trans)
else:
print("Not in the dictionary!")
RE: Translating language in python - Liquid_Ocelot - Apr-01-2017
So just for clarification in terms of the instructions:
"Using nested if-statements (not lists), write a function that finds and prints the translation of
either cat or dog from English into German, French or Spanish."
Would this be within the guidelines?
translate = input("What language do you want to translate? French, German or Spanish:")
words = input("Please state the word :")
if translate == "French":
if words == "cat":
print("The translation of cat into French is 'chat'")
elif words == "dog":
print("The translation of dog into French is 'chien'")
else:
print("I can not understand")
if translate == "German":
if words == "dog":
print("The Translation of dog into German is 'hond'")
elif words == "cat":
print ("The translation of cat into German is 'katze'")
else:
print("I can not understand")
if translate == "Spanish":
if words == "dog":
print("The translation of dog into Spanish is 'perro'")
elif words == "cat":
print ("The translation of cat into Spanish is 'gato'")
else:
print("I cannot understand")

Yes, but the OP said they can only use "requires me to use nested if-statements (not lists) in order to write a function". I presume that means dictionary's as well :-). Though alicarlos13's answer fits the nested "if"'s it's not really a function, though that criteria might not mean what it implies. If it does mean what it says, it would be a simple matter to convert to a function.

Yup no dictionaries either :)

It very confusing, i mean are "lists" considered "tuples"/"dictionaries"; Guess the context of the question is not really clear.

else:
print("I can not understand")There is something not correct here, so the users input "GERMAN" language and is supposed to enter the words in "ENGLISH". And converting it into a simple function
def trans(language, words):
if language == "French":

print("English => Dog")

yeah its thrown me off too.
I guess as long as I am getting the user to
1 select a language to be translated
2 enter either dog or cat
3 then print the translated word in chosen language from english
I think I am on the right track.
Also a footnote does state If you use and in the if conditions, an alternative solution could use just the if-elif construct, without
any nested if statements.
RE: Translating language in python - sparkz_alot - Apr-01-2017
OK, alicarlos13's last post meets all the criteria of the original post (well sort of
), you will have to tinker a bit with the statements in order to get the output you want, but the structure is there as requested...nested 'if' statements contained within a function.Quote:@alicarlos13 wrote:

yes, I think. "words" is cat or dog in English and "language" is the equivalent output in either French, German or Spanish.
