Write a function dimensionflip() that takes a list of observations in meters and outputs a list with the corresponding observations in centimeters. Your function should only convert dimensions of positive entries; therefore, a negative dimension in meters must not be changed. For example: Input1: [1,4,5] Output1: [100,400,500] Input2: [5,9,-8,6] Output2: [500,900,-8,600] The values within the input list should not be changed following a call to this function. Write a function gradeit() that takes a number x as grade in number and return a letter grade. The valid number range is between 0 and 100. The function should do the following: return "A" if number is greater than or equal to 80 return "B" if number is greater than or equal to 50 return "C" if number is less than 50 return "I" if number is out of range You are NOT allowed to use the following constructs unless specified in the assignment directions. Using the following constructs will result in 0 (zero) for the entire submission (assignment, timed test, etc.). The restricted items are as follows: Concepts not discussed in lectures yet . String functions Member functions Exceptions (can use): len () and x-x+[y1, y2,y3] Built-in functions & types Exceptions (can use): str(), readline(), open(), close(), write(), read(), range()..split() . Cannot use append, sort, etc. Cannot use "Slicing" Cannot use "list comprehension" Cannot use "not in" (together) Cannot use "in" not allowed with conditionals Exception (can use): with range() Cannot use" and {} Exception (can use): mathematical operations (multiply & exponents) . Data type functions . Exceptions (can use): int(), str (), float () . Break . Continue . Nested Constructs Exceptions (can use): 2-D list . Multiple returns & Multiple assignments Recursion (not allowed unless the question explicitly states otherwise) Functions within functions (Definitions) -- invocation is fine Default Parameters . Global variables Keyword as variable names . while true or without proper condition
