Then calls the given function on each element in the sequence and returns an Iterator to iterate over the result objects. Map() function in python accepts 2 arguments i.e. Convert list to string using map() in python It joined all the integers in the list to create a string, using logic provided by lambda function. Then converts both the arguments to string and join those arguments with a delimiter in between.

A lambda function that accepts 2 arguments.

Convert list of integers to string using reduce() in python list_of_num = įinal_str = functools.reduce(lambda a, b: str(a) + delimiter + str(b), list_of_num) It joined all the elements in the list to create a string, using logic provided by lambda function.

A lambda function that accepts 2 arguments and join those arguments with a delimiter in between.

Here we passed two arguments to the reduce() function, Let’s use this to convert list to string, list_of_words = įinal_str = functools.reduce(lambda a,b : a + delimiter + b, list_of_words) When it consumes all the items in sequence then the final result value will be returned. For generating the value it will, pass the first two values to given function argument and then keeps on calling the same function with result and the next argument. This function generates a single value from all the items in given iterable sequence. Convert list to string using reduce() in python reduce(function, sequence)įunctools module in python provides a function reduce(), which accepts a iterable sequence as argument and a function as argument. We joined all the elements by using a white space as delimiter. Output: This is a sample 44 55 66 program

# Covert list of different type of items to string Then we can join all the items in the new list of strings to create a string.įor example, mix_list = For that we need to call str() on each item of the list to convert it to string. We can do using join() function, but we need to first convert list of different type of elements to a list of strings. Final string should be like, This is a sample 44 55 66 program We want to convert this list to a string by joining all the items in list in string representation with given delimiter as separator between items. Suppose we have a list that contains different type of elements like int, float, strings etc, mix_list = Convert list of different type items to string using join() in python

For example, list_of_num = įull_str = ' '.join() We can do using join() function, but we need to first convert list of ints to a list of strings and then we can join all the items in that list to create a string with separator. We want to convert this list of ints to a string by joining all the integers in list in string representation with given delimiter as separator between items. Suppose we have a list of integers, list_of_num = Convert list of integers to string in python using join() in python In this example, while calling the function convert_list_to_string(), we passed a comma ‘-‘ as delimiter / separator, therefore it joined all the items in list using ‘-‘ as separator. ''' Convert list to string, by joining all item in list with given separator.įull_str = convert_list_to_string(list_of_words, '-') For example, def convert_list_to_string(org_list, seperator=' '): We can also use any custom delimiter while converting a list to string.
