In Python, if a name is intended to be "private", it is prefixed by one or two underscores. Private variables are enforced in Python only by convention. Names can also be suffixed with an underscore to prevent conflict with Python keywords. Prefixing with double underscores changes behaviour in classes with regard to name mangling.
The bank will examine the beneficiary's demand and if it complies with the terms of the letter of credit, will honor the demand. [12] Most letters of credit are governed by rules promulgated by the International Chamber of Commerce known as Uniform Customs and Practice for Documentary Credits. [13]

[4] Java has public, package, protected, and private; package is the default, used if no other access modifier keyword is specified. The meaning of these modifiers may ...
The Uniform Customs and Practice for Documentary Credits (UCP) is a set of rules on the issuance and use of letters of credit. The UCP is utilized by bankers and commercial parties in more than 175 countries in trade finance. Some 11-15% of international trade utilizes letters of credit, totaling over a trillion dollars (US) each year.
Honor confidentiality. Unless required by law or any other ethical guideline, a programmer must keep secret any additional information related to their employer that arises from working in a project. From Software Engineering Code of Ethics and Professional Practice [ 5 ] (IEEE, ACM):
Private (or class-private) restricts access to the class itself. Only methods that are part of the same class can access private members. Protected (or class-protected) allows the class itself and all its subclasses to access the member. Public means that any code can access the member by its name.
Python properties may be used to allow a method to be invoked with the same syntax as accessing an attribute. Whereas Meyer's UAP would have a single notation for both attribute access and method invocation (method invocation syntax), a language with support for properties still supports separate notations for attribute and method access.
Some languages like Smalltalk and Ruby only allow access via object methods, but most others (e.g., C++, C#, Delphi or Java [12]) offer the programmer some control over what is hidden, typically via keywords like public and private. [8]
