Write a Python program that allows user to repeatedly enter a series of float numbers, until the string end is entered. For each number entered, calculate and print its double (multiply by 2). Note that . (1) Sentinel must be used. • (2) The placement of data type conversion is critical. [Run your program in Python IDLE to verify if it works correctly as described above] Enter a float number or 'end' to stop: 2.4 The double of 2.4 is 4.8 Enter a number or 'end' to stop: 4.123 The double of 4.123 is 8.246 Enter a number or 'end' to stop: end

Question 3 - (this question MAY appear on the assignment quiz) Write a Python program to solve the following problem: Given a two-dimensional list/table containing hexadecimal colour codes representing a picture, write functions to look for the corresponding colour names in another two-dimensional colour lookup table (see below) and generate a resulting two-dimensional table containing the names of the colours in the appropriate locations, corresponding to where the colour code was in the original hexadecimal table. See sample expected output below. Call the file containing your program, colour_codes.py. Include the following functions in your code: • a function to find the appropriate row, in the colour lookup table, corresponding to the first three digits of the colour code in the picture; the function should take, as parameters, the lookup table and a string containing the first three digits of the colour code and return the code's row location (e.g., partial code "FF0" would give 4…
