Method 3: Using join() & List comprehension Algorithm (Steps) Then, using the map() method, we converted each element of the list to a string and used the join() function to get the result. We took an example list with some random string, integer, and floating point values. The following program returns the size of the list using the for loop (Naive method) − This function connects sequence elements to form a string) and then converts the result to a string separated by commas. The join() function(join() is a string function in Python that is used to join elements of a sequence that are separated by a string separator. It maps each element of the input list to the str function given and returns the resultant list of items. Get the comma-separated string from the list by passing the str function, list as arguments to the map() function. Algorithm (Steps)Ĭreate a variable to store the input list. Let's take a look at how to solve this problem. TypeError: sequence item 4: expected str instance, int found When we use the join() function, we get the following type error. Which comprises strings, integers, and floating point numbers. map(function, iterable)Ĭonsider the following list, list = Following that, the map() function maps the items of the iterable using the specified function. The map() function accepts iterable objects like lists, tuples, strings, and so on. On executing, the above program will generate the following output − The result string after joining the list with comma separated: The following program returns the size of the list using the len() function − Print the result of a comma-separated string. Here we pass delimiter as ‘,’ to separate the strings with comma(‘,) This function connects sequence elements to form a string) and create a variable to store it. Get the comma-separated string from the list by passing the list as an argument to the join() function(join() is a string function in Python that is used to join elements of a sequence that are separated by a string separator. Method 1: Using join() method Algorithm (Steps)įollowing are the Algorithm/steps to be followed to perform the desired task −Ĭreate a list and add some dummy strings to it. We will return the string separated by commas from the given list. −Īssume we have taken a list containing some random elements. In this article, we will show you how to get a comma-separated string from a list using python. Square brackets are used to denote it, and a comma (,) is used to divide two items in the list. In other programming languages, a list is equivalent to an array. In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float.
