If you just want to know the best way to print a list in Python, here's the short answer: Pass a list as an input to the print() function in Python. Use the asterisk operator * in front of the list to “unpack” the list into the print function. Use the sep argument to define how to separate two list elements visually.
When you wish to print the list elements in a single line with the spaces in between, you can make use of the "*" operator for the same. Using this operator, you can print all the elements of the list in a new separate line with spaces in between every element using sep attribute such as sep=”/n” or sep=”,”.
use join() function to print array or without square brackets or commas.
How to Convert a Python List into a Comma-Separated String? You can use the . join string method to convert a list into a string. So again, the syntax is [seperator].
