Python

Is each of the following True or False Any program that can be written using only function definitions and calls, the basic arithmetic operators, assignment, and conditionals will run in constant time. Newton's method will always converge on a correct root of a function. In Python, dictionaries are immutable. The value of *math.sqrt (2.0)*math.sqrt (2.0) == 2.0' is True. One should always avoid iteration when a recursive solution is possible. Typically, the use of functions in a program reduces the total number of lines of code. In Python, retrieving the value associated with a dictionary key takes roughly constant time
