Please make sure not to have any statements outside of any functions. There is only one statement which is outside of any function which is given below:

i-e main( )

Also, make sure to code in python IDLE when providing solution

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 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) : /en () 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
