In Python, you can add the values of a list together using a loop, such as a for loop, and a variable to keep track of the sum. You can also use the built-in “sum()” function to add the values of a list together. 

  • sum(): The sum() function takes an iterable as an argument, such as a list, and returns the sum of its elements. 

You can also use “list comprehension” to add the values of a list together. 

  • List comprehension: Applying an operation to each member of an existing list or other iterable and gathering the results in a new list is a condensed method of producing a new list in Python. 

You can otherwise use the “reduce()” function from the “functools” module to add the values of a list together. 

  • reduce(): This function applies a function cumulatively to the iterable's elements by taking an iterable and a function as arguments. 
  • functools module: The functools module is a built-in Python module that provides several tools for working with functions and functional programming.
