It could be enough for us to use it just as a multiplication operator. Ed described his enthusiasm for the power and simplicity of Asterisk when he found he could write a quick Perl script to help his young daughter improve her math skills. Besides using as a multiplication operator, there are some elegant and powerful uses of it in Python, which will help our code become more “Pythonic”. .

To generate asterisk pattern we first read value of n from user. The library currently supports AGI, AMI, and the parsing of Asterisk configuration files. After reading n we generate asterisk (*) pattern having n stars on each segment in the pattern. For numeric data types, * is used as multiplication operator. Because of this inconvenience, it’s not common to extract items of a dict by asterisks. Obviously, we can use for-loops to iterate all items and add them to a new list one by one: This way can accomplish our mission, but the code looks so long and not very “Pythonic”.
