In Python, you can place a comma after every item in a list, dict, or set constant, including the last item. That way, you can just remember to always end your lines with a comma and thus avoid the comma placement juggling that would otherwise be required. note: Python Docs:“String ...
the concatenation of two lists using the+operator oritertools.chain(), and the combination of a list with a set. Additionally, you will also learn using thestrip()method for removing leading
Another form of concatenation is with the application of thejoinmethod. To use the join method, we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with ...
including using the+operator,str()function, and f-strings, you can effectively create dynamic strings and improve the readability of your code. Additionally, learning about list concatenation, joining lists, and
In this code snippet, you define a list of colors using string objects separated by commas and enclose them in square brackets.Similarly, tuples are also collections of arbitrary objects. To define a tuple, you’ll enclose a comma-separated sequence of objects in parentheses (()), as shown...
Python knows a number ofcompounddata types, used to group together other values. The most versatile is thelist, which can be written as a list of comma-separated values (items) between square brackets. Lists might contain items of different types, but usually the items all have the same typ...

In short, a list is a collection of arbitrary objects, somewhat akin to an array in many other programming languages but more flexible. Lists are defined in Python by enclosing a comma-separated sequence of objects in square brackets ([]), as shown below:...

In Python, the argument list is defined partially with leading commas and partially with trailing commas. This conflict causes situations where a comma is trapped in the middle, and no rule accepts it. Note: The trailing comma problem is fixed in Python 3.6. The remarks in this post discuss...
