creat a program with function calculator function that take operand and operators from users

True or False : The concept of function abstraction hinders our code development by confusing us with the details of the function.

Predefined functions are less efficient than those that are defined by the user.

Why is it necessary to create function prototypes in a program with user-defined functions?

Predefined functions are less efficient than those that are defined by the user.

What are the assertions that describe how a function works?

Python without Def function Problem Statement  Define and implement a function time_delta that takes two string parameters (time1 and time2) and returns the difference between them (as a string). You may assume that the second time will always be after the first time, both times will always be on the same date, and military time will be used (no a.m. or p.m.). Examples time_delta(04:15:36, 16:35:27) ➞ (12:19:51) time_delta(02:06:05, 06:09:10) ➞ (04:03:05) Sample Input 1 "04:15:36" "16:35:27" Sample Output 1  "12:19:51"

Programming Skills: Complete the function egg_category which returns a str describing an egg's category given its int weight in grams. Here is a table specifying the weight ranges if an egg's weight is on the boundary between two category ranges, it is assigned the smaller category. Category Small Meduim Weight no more than 50 grams 50-57 grams Category Large Jumbo Weight 57-64 grams more than 64 grams def egg_category (weight): %# Return a str describing the category of an egg of the specified int weight.
