List of all programming languages in Select Field

I am trying to create a WtForms SelectField which will show all the various programming languages available to choose from.

Its almost impossible to type all the programming languages listed here in the select field. How to implement this kind of select field.

Code

class SkillForm(Form):
    skill = SelectField('Languages', choices=[('c++', 'C++'), ('python', 'Python'), ('text', 'Plain Text')])
    submit = SubmitField('Submit')

    def validate_skill(self, field):
        if Skill.query.filter_by(author_id=current_user.id).filter(Skill.skill==field.data.lower()).first():
            raise ValidationError('Skill already exists.')

I have just added three skills for just testing purpose and it works and i need to include all the languages possible and its almost impossible to write them all in choices, so what other option do i get from that.

Any help would be appreciated.

Answer

You can get all the languages from the website running a script:

#Get the html
import urllib2
response = urllib2.urlopen('http://en.wikipedia.org/wiki/List_of_programming_languages')
html = response.read()

#Parse it with beautifulsoup
from bs4 import BeautifulSoup
soup = BeautifulSoup(html)

langs = []

#Parse all the links.
for link in soup.find_all('a'):
    #Last link after ZPL, the last language.
    if link.get_text() == u'Top':
        break
    if link.get_text() == u'edit':
        pass
    else:
        langs.append(link.get_text())

# find u'See also'
see_also_index_ = langs.index(u'See also')
# strip out headers
langs = langs[see_also_index_+1:]

print langs
