In this article, I have explained how to convert a list of lists to a tuple of tuples in python by using tuple()+list comprehension, enumerate(), map() + tuple(), and recursive functions with examples. # Updated tuple of tuple: ((15, 8, 26), (16, 12, 4), (13, 48, 24)) Our updated program is running successfully now that 1 is converted from a string to an integer before using the choice variable to index the list, giving the. Similarly, you can also convert a list of lists to a tuple of tuples using a recursive method, you can define a recursive function that takes in a list as input and iterates through its elements. This technique, however, would return a list of characters since Python would not be able to tell where. The map() function returns a map object, which you convert to a tuple using the tuple() function. To create lists from strings, use the list function (). You can use the map() function to apply the tuple() function to each sublist in lists. For example, you first define a list of lists called lists. You can also use the map() function along with tuple() to convert. For each sublist, you convert list to a tuple using the tuple() function. then use the enumerate() function to get the index and value of each sublist in lists. For example, you first define a list of lists called lists, use the list comprehension to iterate over each sublist lists. You can also use the enumerate() function to convert a list of lists to a tuple of tuples. # Convert list of lists to tuple of tuples For example, you can use a list comprehension to iterate over each sublist in the lists, and then apply the tuple() function to each sublist to convert it to a tuple. You can convert a list of lists to a tuple of tuples in Python, you can use a list comprehension and the built-in tuple() function to convert each sublist to a tuple.
Convert List of Lists to Tuple of Tuples Using tuple() + List Comprehension Return (tuple(List),) + list_to_tuple(List)Ģ. are quite a lot of string methods and you can find the list in the online python. # Example 3: Using map() + tuple() function If we want them to be converted to integers, we call the function int. Result = tuple(tuple(i) for x,i in enumerate(lists)) Result = tuple(tuple(sublist) for sublist in lists) # Example 1: Convert a list of lists to a tuple of tuples # Quick examples of convert list of lists to tuple of tuples If you are in a hurry, below are some quick examples of how to convert a list of lists to a tuple of tuples.
Quick Examples of Convert List of Lists to Tuple of Tuples Let’s now review a simple use case, where we’ll have a list with strings.Python convert List to Tuple - Python Tutorial 1. Use Case: Why Convert Strings to Integers? You can easily convert string list items into int items using loop shorthand in python. You’ll get the same results as the first approach: The strings will be converted to integers: Īs before, you may apply the syntax below in order to verify that the strings were converted to integers: my_list =
Using List Comprehension to Convert Strings to Integers in a Python ListĪlternatively, you may use the second approach to convert your strings to integers: my_list = įor our example: my_list = The portion in yellow represents the strings prior to the conversion, while the portion in green represents the integers following the conversion: Optionally, you may perform a further check to verify that the strings were converted to integers: my_list = Once you run the code, you’ll see the list of integers (without any quotes around the values): You can then use map in order to convert the strings to integers: my_list = Here is how the list with the strings would look like: Suppose that you have a list that contains 5 values, where each value is stored as a string (by placing each value within quotes): my_list = 1 Let's say I have a list of unknown words: l 'bike', 'blue car', 'wheel', 'car' I would like to write a script to determine which word appears twice in the list. Using Map to Convert Strings to Integers in a Python List You may apply either of the two approaches below in order to convert strings to integers in a Python list:
