Instructions In Chapter 4, we developed an algorithm for converting from binary to decimal. You can generalize this algorithm to work for a representation in any base. Instead of using a power of 2, you will write a program that converts any base between 2 and 16. Recall that for numbers 10-15 we use letters A - F. In convert.py, define a function named repToDecimal that expects two arguments, a string, and an integer. The second argument should be the base. For example, repToDecimal("10", 8) returns 8, whereas repToDecimal("10", 16) returns 16. convert.py + 1 # Put your code here 2 3 # A main for testing your program 4 def main(): 5 6 7 """Tests the function. """ print (repToDecimal('10', 10)) print (repToDecimal('10', 8)) print (repToDecimal('10', 2)) print (repToDecimal('10', 16)) 8 9 10 11 # The entry point for program execution 12 if __name__ == "__main__": 13 main()

Programming Exercise 5.5 Instructions abl In Chapter 4, we developed an algorithm for converting from binary to decimal. You can generalize this algorithm to work for a representation in any base. Instead of using a power of 2, you will write a program that converts any base between 2 and 16. Recall that for numbers 10 - 15 we use letters A - F. In convert.py, define a function named repToDecimal that expects two arguments, a string, and an integer. The second argument should be the base. For example, repToDecimal("10", 8) returns 8, whereas repToDecimal("10", 16) returns 16. • The function should use a lookup table to find the value of any digit. Make sure that this table (it is actually a dictionary) is initialized before the function is defined. • For its keys, use the 10 decimal digits (all strings) and the letters A... F (all uppercase). The value stored with each key should be the integer that the digit represents. (The letter A associates with the integer value 10, and so on.) • The main loop of the function should convert each digit to uppercase, look up its value in the table, and use this value in the computation. A main function that tests the conversion function with numbers in several bases has been provided. An example of main and correct output is shown below: def main(): 10 8 2 16 print (repToDecimal('10', 10)) print (repToDecimal('10', 8)) print (repToDecimal('10', 2)) print (repToDecimal('10', 16)) convert.py + 1 # Put your code here 2 3 # A main for testing your program 4 def main(): 5 6 7 """Tests the function."▪▪ print (repToDecimal('10', 10)) print (repToDecimal('10', 8)) print (repToDecimal('10', 2)) print (repToDecimal('10', 16)) 8 9 10 11 # The entry point for program execution 12 if __name__ == "_ "__main__": 13 main() 14
