I am posting some problem on functions for practice. I hope you find it useful. the function format is also mentioned on the side. reply with the answer for 4th question for now. Rest can be used for further practice or discussion among your classes to understand and learn better.
 Write a function to see if numbers of two integers add up to the same number. function_name(number1, number2). example : individual numbers of number 321 and 123 add up to 6.
 Write a function to return all possible combinations of two numbers in a list that adds up to a target number.
function_name(list, target)
 write a function to convert weights from kilogram to pound and viceversa. function_name(weight). ask for user input and convert accordingly.
 write a function to return number of words in a sentence. function_name(‘string’)
