![]() Let me use multiple iterables along with map lambda. Next, (lambda a:a.capitalize(), fruits) uses capitalize to capitalise the first character in each fruit. (lambda a:a.upper(), fruits) uses upper and converts each fruit to uppercase. (lambda x: x * x, numbers) returns the square of each item in numbers. You can use the lambda expression inside this map function to make the code easily readable. ![]() Next, the len finds the length of each item or fruit in the fruits. Here, the factorial func finds the factorial of each element of numbers. For this Python demo, we used the factorial method and len methods. Here, we are using the built-in function as the arguments. Next, we are using the same scenario on fruits (string). For example, (addition, 10, 150) becomes 160. Here, (addition, numbers1, numbers2) means it takes the first value from two lists and applies addition and so on. In this example, we created a map function that accepts two arguments and returns the sum of those values. Until now, we are using this on one iterable (single). Print('Numbers List = ', list(result)) Chars List = + symbol on characters or strings concat them. Here, the (addition, chars) means, for each character in the chars, it calls the addition. We are using both the numeric values and the characters. TIP: Please refer to the List article to understand them. The last print statement converts it to a list and prints the values. So, we have to convert that object to any of the Iterable. Next, we used it to assign that added to each item in numbers.īy default, this function returns the map object as an output value. Next, we declared a list of numbers from 10 to 50. It adds a number to itself and returns that value. In this map example, we declared a function called addition. ![]() In this section, we discuss how to use this along with examples, and the basic syntax of the Python map function is map(function_name, iterables.) Python map Values Example Next, it returns a list of the result values. ![]() The input iterable,, , ] is a list.The Python map function applies the user given function to each item in an iterable such as a list, tuple, etc. # Generic Function to print the iterator and its content # Function to print the map outputĪlso, we’ll use one more generic function to print the iterable. It calculates the length of iterable and returns in a map object.īelow is a method to print the map object. So, here it is: # User-defined function to pass to map() We’ll now give several examples using map() so that you can clearly understand what does it do and how should you use it.īut before beginning, we need a user-defined function that we can pass as the first argument to map(). Map(in_function, iterable1) Map() Function Examples Its syntax is as follows: # Python map() syntax In this case, the map() call stops after finishing up the shortest iterable argument. However, if you provide multiple iterables, then the function will be called with each of their elements as arguments. If you pass only one iterable, then map() calls the function for each of its elements and returns map object with results. The first argument is a user-defined function, and then one or more iterable types. The map() function takes at least two parameters. 5 map() function with multiple iterables.4 Python map() with the anonymous function.2.5 Dictionary as iterable in map() function.2.3 Tuple as iterable in map() function.2.1 String as iterable in map() function.
