Exam task for Sedreh Nassirnia

YakutovDmitriy commented 5 years ago

Main requirements

Your program should never fail.

You are free to implement the task as you want. In particular, if there are some uncertainties, you have to decide what to do.

You are free to add some functionality. Please describe all features you added.

Implement application `translate.py` to translate words.

You should store dictoinary in file dict.tr. Note that one string can have different meanings in different languages (e.g. Ja is Yes in German and I in Russian). You can assume that one string can have no more than one meaning in one language.

You should assume that name of language do not depend on case: English is the same language as english.

Add: python translate.py + <Language-1> <Word-1> <Language-2> <Word-2> ...

Command should add list of words <Word-1> ... in languages <Language-1> ... with the same meanings.
Translate: python translate.py ? <From language> <To language> <Phrase>

Command should translate phrase <Phrase> from language <From language> to language <To language>. <Phrase> is list of several words separated by spaces: <Word-1> ... <Word-n>. If one of the strings from phrase is not present in language <From language> print a message about it. If one of the words have no translation to language <To language> print a message about it. Otherwise you should print translated phrase to stdout.

Do not forget to preserve the case! For example:
```
python translate.py ? English Russian I love you
> Ja lublu ti
python translate.py ? EngLiSh russian I love YOU
> Ja lublu TI
```

Hello!

Some issues I want to mension:

Your code doesn't work with dict.tr example I shared with you. It doesn't read line Russian: mem English: meme correct because of whitespaces. If you wanted to change format you could change file dict.tr.
Your translator is case-sensitive: It is able to translate ja lybit ti but not Ja lybit ti
If I write something like python translate.py + russian megust english it adds one word in russian. I expected to see an error message

6.5 points
