The output on screen Your program must define and use the following functions:1. printHeader(...): prints on screen the three lines header of the table as shown in the sample output(Fig. 2).2. getCoordinates(...): receives one parameter representing a text line read from the input file, and itreturns four float values x1, y1, x2, y2. In case of any wrong value format, the function returns 0.0,0.0, 0.0, 0.0.3. computeSlope(.-.): receives four parameters representing the values x1, y1, x2, y2 and returns theslope value m that should be computed according to the given formula above. If x2 is equal to x1the computeSlope function returns an infinite value. In Python, the infinite value is a float constantvalue called inf (available in math library). Thus, you need to import inf from the math library asfollows:from math import inf4. main(...): the main function receives the name of the input file 'points.txt'. This function opens theinput file for reading, reads data from it, calls the various functions and finally prints the results onscreen. If the input file is not found, an exception is raised and an error message will be displayed.
