[Tutor] Python Script: Downloading Youtube videos by search result
Dear All, I want to download some music from youtube.There are already marvellous python scripts like youtube-dl which downloads videos and playlists from numerous sites,but what I want to do is to download videos from youtube with a search string. The user will give a search string, and the script will download first 20(say) videos from the youtube.The script will use youtube-dl on the backend and avconv tool for video to MP3 conversion etc. How should I proceed to make such a script. I am a newbie in Python but I am sure with your guidance I can pick it up quite fast. :) Cheers, Sayan -- -- *Sayan Chatterjee* Dept. of Physics and Meteorology IIT Kharagpur Lal Bahadur Shastry Hall of Residence Room AB 205 Mob: +91 9874513565 blog: www.blissprofound.blogspot.com Volunteer , Padakshep www.padakshep.org ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

POSIX/Linux uses a forward slash instead of a backslash (py: os.sep), and the delimiter in PATH is a colon instead of a semicolon (py: os.pathsep). There's no convention I know of to use trailing slashes. You might also consider using the PEP 405 "venv" module: http://www.python.org/dev/peps/pep-0405 When you "activate" the environment it prepends the "Scripts" (or "bin") directory to PATH. The option "--symlinks" requires an elevated security token on Windows, but just to create the virtual environment. If you'd rather copy over the required DLLs, there's a "--upgrade" option for when you upgrade to Python 3.4, etc. > An entirely different question as long as I'm here.

[Tutor] hard time importing a module
hi I have a question about modules ... Im trying to use a 3rd party module called pywinatuo. It said I had to install 2 other modules. 1 was called sendkeys.py, the other was ctypes. Ctypes was included in the python library I had, but sendkeys was not. After I found SendKeys, I put it in a directory I found in sys.path, and then type import SendKeys. I got an error because sendkeys was trying to import from another file called _sendkeys. After searching I found _sendkeys, but it is .c I know that you can somehow extend python with c from reading this article : http://docs.python.org/2/extending/extending.html But... how do I get the interpreter to recognize the _sendkeys.c file when sendkeys.py trys to import it ? I get errors right away since c uses * to comment so python doesnt recognize it and errors on all of the comments from _sendkeys.c Basically how do I correctly import this module that doesnt have a setup.py ? ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Normally, a Python module is not installed by manually copying the files to the appropriate places but by running 'python setup.py install' in the terminal. This will compile any C code and copy files to the appropriate places. Note that you will need to have separately installed a C compiler to be able to compile C code. > > I know that you can somehow extend python with c from reading this article : > http://docs.python.org/2/extending/extending.html Try reading this one instead: http://docs.python.org/2/install/index.html > > But... how do I get the interpreter to recognize the _sendkeys.c file when > sendkeys.py trys to import it ?

Re: [Tutor] How to find reverse pair words in a list of Words that has to be accessed through a URL
Hi Don I'm a beginner in Python Programming. I'm using python 3. I wrote a program that checks whether given two words are reverse pair or not and outputs TRUE/FALSE. *def reverse_pair(a,b):* *return list(a)==list(reversed(list(b)))* * * * * But how to write a program that finds all the reverse pairs in the given word list, eg: how to find the reverse pair words in a list of 20 words. And that to how to access those list of words form a URL. Because with the above code we can only find out whether the given 2 words are reverse pair or not, that's it. I'm thinking of using the below code which is written for Python 2.7. Code: def reverse_pair(word_list, word): """Checks whether a reversed word appears in word_list. word_list: list of strings word: string """ rev_word = word[::-1] return in_bisect(word_list, rev_word) if __name__ == '__main__': word_list = make_word_list() for word in word_list: if reverse_pair(word_list, word): print word, word[::-1] On Fri, Apr 19, 2013 at 2:05 PM, Don Jennings wrote: > > On Apr 19, 2013, at 4:56 PM, Chetan Sai wrote: > > > Here is my question: > > > > "Two words are a “reverse pair” if each is the reverse of the other. > Write a program that finds all the reverse pairs in the word list.

yeah, but those exceptions are easy to catch as you generate the reversed list:
if reversed(word) == word
An easy mistake to make, but reversed() returns an iterator which will only
compare equal to itself:
py> reversed("abc")
You need to convert the reversed object back into a string:
py> "".join(reversed("abc"))
'cba'
But the best way to reverse a string is with a slice:
py> 'abc'[::-1]
'cba'
The syntax is a little obscure, but "slicing" takes between 0 and 3 arguments,
written inside square brackets [ ] and separated by colons. The full form of a
slice is:
string[start:end:step]
where start defaults to the beginning of the string, end defaults to the end of
the string, and step defaults to 1. If step is 1, you can leave it out:
string[start:end]
otherwise you need to include colons to mark the missing values:
string[2::3]
says to return a slice of the string, starting at character 2, going to the end,
and taking every third character. (Remember that counting starts at 0 in Python,
not 1, so character 2 is the *third* character.)
py> "python is cool"[2::3]
'tnso'
A negative step goes backwards, so a fast and efficient way to reverse a string
or other sequence is to use slice it using [::-1].
And its a bit of a moot point whether you should
perhaps count a palindromic word as a pair of itself...
That word you use, I do not think it means what you think it means, to quote
the Spaniard.
A moot point is a point which is not relevant. If your house has just been
flattened by a hurricane, it is a moot point whether or not you left the front
door unlocked. I think it is quite relevant whether or not palindromes should
count or not.
