Answer 1
Concatenation of a byte type, which is an immutable type, and a str type isn't permissible in the Python 3 standard; any attempt to concatenate these two types will raise TypeError.
Answer 2
The type-hinting support introduced in Python 3 is only intended to provide greater clarity in documenting the methods and the parameters and doesn't enforce any standards on the operations.
Answer 3
Beyond the functional and nonfunctional requirements, a software requirements specification document also specifies other requirements, such as UI, performance, business, and market requirements.
Answer 4
The various kinds of requirements are categorized as follows:
- Must-have requirements: These are requirements that must be present inside a system. If any are missing, their absence will affect a critical functionality in the system.
- Should-have requirements: These are requirements that, if present, will enhance the functionality of the application.
- Could-have requirements: These are requirements that are noncritical in nature. If they are missing, they won't have any impact on the application's functionality.
- Requirements wish list: These are requirements that the stakeholders might want to see in future updates of the application.
Answer 5
Once the software requirements specification document has been generated, the next steps in the process include the design phase of the software. In the design phase, the structure of the software application is decided upon and decisions are made regarding the possible technology stacks that might be used to build the software.
