A basic character field but server side the django validates whether the values is convertible to a UUID(Universal unique ID) forms.widgets.TextInput() Text: forms.ComboField(fields=[field_type#1,field_type#2]) Works just like CharField, Heredjango form fields are enforced with data pass rules on the server side. This method is useful if you need to perform a mathematical operation on a value. It cannot be used to dynamically switch Python versions. To show it in binary — that is, as a bicimal — divide binary 1 by binary 1010, using binary long division: The division process would repeat forever — and so too the digits in the quotient — because 100 (“one-zero-zero”) reappears as the working portion of the dividend.
