( full tutorial on yattag.org )

Basic example

Nested html tags, no need to close tags.

from yattag import Doc

doc, tag, text = Doc().tagtext()

with tag('html'):
    with tag('body', id = 'hello'):
        with tag('h1'):
            text('Hello world!')

print(doc.getvalue())

Html form rendering

Yattag can fill your HTML forms with default values and error messages. Pass a defaults dictionnary of default values, and an errors dictionnary of error messages to the Doc constructor. Then, use the special input, textarea, select, option methods when generating your documents.

Example with default values

from yattag import Doc

doc, tag, text = Doc(
    defaults = {'ingredient': ['chocolate', 'coffee']}
).tagtext()

with tag('form', action = ""):
    with tag('label'):
        text("Select one or more ingredients")
    with doc.select(name = 'ingredient', multiple = "multiple"):
        for value, description in (
            ("chocolate", "Dark chocolate"),
            ("almonds", "Roasted almonds"),
            ("honey", "Acacia honey"),
            ("coffee", "Ethiopian coffee")
        ):
            with doc.option(value = value):
                text(description)
    doc.stag('input', type = "submit", value = "Validate")

print(doc.getvalue())

Example with default values and errors

from yattag import Doc

doc, tag, text = Doc(
    defaults = {
        'title': 'Untitled',
        'contact_message': 'You just won the lottery!'
    },
    errors = {
        'contact_message': 'Your message looks like spam.'
    }
).tagtext()

with tag('h1'):
    text('Contact form')
with tag('form', action = ""):
    doc.input(name = 'title', type = 'text')
    with doc.textarea(name = 'contact_message'):
        pass
    doc.stag('input', type = 'submit', value = 'Send my message')

print(doc.getvalue())
