In this example, I’ll explain how to uselist comprehensionsfor the conversion of lists of integers to lists of strings. Have a look at the following Python syntax and its output: sl_str2=[str(x)forxinsl_int]# list comprehension methodprint(sl_str2)# print output of list comprehension#...
join(str_list) print(join_str) # Output: "Python is fun" # For a list of numbers, convert each element to a string first num_list = [1, 2, 3] delimiter = " " # Define a delimiter num_list_string = map(str, num_list) # Convert each element into a string first join_num_...
As you can see based on the previously shown output of the Python console, our example data is alist objectthat contains six elements. Let’s check the data type of each item in our list: foriinmy_list:print(type(i))# Return data types of all list elements# <class 'str'># <class...
