Through the previous study, we have learned how to customize functions in Python. Today we will talk about params in Python function parameters

What are params in python

If we already know the number of function parameters, we can just pass it to the function directly, but in most cases , we don’t know the number of function parameters, how to solve this? This uses the params parameters in Python!

PythonThe parameter collection mechanism uses the asterisk "*" to implement . Here, a "*" is added in front of the specified parameter params. "*" means to use params parameters to collect An indefinite number of parameters are passed in, and the collected parameters are stored in params in the form of tuples. If no parameters are passed in, params is an empty tuple

For example

As you can see from the above, no matter how many parameters are passed to the function, it will work well through the params parameter collection mechanism. solution!

How to concatenate two lists in python 3?May 14, 2025 am 12:09 AM

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Python concatenate list stringsMay 14, 2025 am 12:08 AM

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
