FAQs on Lesson 04_04 Arguments with default values and keyword arguments Video Lecture - The Julia Computer Language: Numerical Analysis and Computational Science - Database Management
| 1. What are arguments with default values in Python? |  |
Ans. Arguments with default values in Python are parameters that are assigned a default value in the function definition. If a value is not passed for that parameter when calling the function, it will use the default value. This allows for more flexibility and simplifies function calls by providing a default value if no value is provided.
| 2. How can default values be specified for function arguments in Python? | |
Ans. Default values for function arguments in Python can be specified by assigning a value to the parameter in the function definition. For example, def my_function(arg1=default_value):. Here, "default_value" is the default value assigned to the "arg1" parameter. If no value is provided when calling the function, it will use this default value.
| 3. What are keyword arguments in Python? | |
Ans. Keyword arguments in Python are arguments that are passed to a function using their parameter names. Instead of relying on the order of the arguments, keyword arguments allow for explicit specification of the parameter values when calling the function. This provides more clarity and can help avoid confusion, especially when dealing with functions with multiple arguments.
| 4. How can keyword arguments be used in Python function calls? | |
Ans. Keyword arguments can be used in Python function calls by specifying the parameter name followed by an equal sign (=) and the corresponding value. For example, my_function(arg1=value1, arg2=value2). This way, the order of the arguments doesn't matter, as long as the parameter names are correctly matched.
| 5. Can default values and keyword arguments be used together in Python? | |
Ans. Yes, default values and keyword arguments can be used together in Python. When using keyword arguments, if a value is not provided for a parameter, it will use the default value assigned in the function definition. This allows for even more flexibility in function calls and provides the option to specify only the necessary arguments while using default values for the rest.
