Iteration is the process of iterating through each element of an object through a for loop. Python’s for syntax is powerful enough to iterate over any object. In python, list / tuple / string / dict / set / bytes are all data types that can be iterated.

Python Coroutines And Asynchronous IO Example

Usually in Python, we use multi-threading or multi-processing to implement concurrent programming. Computing-intensive tasks for cpu are usually implemented by multi-processor because of GIL, while io-intensive tasks can be scheduled by threads to allow threads to relinquish GIL while performing io tasks, thus achieving superficial concurrency.

Four Methods For Merging Python 3 List

1. Use “+” Operator To Merge List Directly. >>> list_1 = [‘java’,’python’,’mysql’] >>> >>> list_2 = [100, 99, 101] >>> >>> print(list_1 + list_2) [‘java’, ‘python’, ‘mysql’, 100, 99, 101] >>> >>> print(list_2 + list_1) [100, 99, 101, ‘java’, ‘python’, ‘mysql’] >>> 2. Use List’s extend Method. The list’s extend method will extend current list …

Global variables are available in all scopes, and local variables are only available in it’s definition function. The order that different scope variables are called is local variable first, then global …
