(1)Prompt the user to enter four numbers, each corresponding to a person's weight in pounds. Store all weights in a list. Output the list. Ex: Enter weight 1: 236.0 Enter weight 2: 89.5 Enter weight 3: 176.0 Enter weight 4: 166.3 Weights: [236.0, 89.5, 176.0, 166.3] (2) Output the average of the list's elements with two digits after the decimal point. Hint: Use a conversion specifier to output with a certain number of digits after the decimal point. (3) Output the max list element with two digits after the decimal point. Ex: Enter weight 1: 236.0 Enter weight 2: 89.5 Enter weight 3: 176.0 Enter weight 4: 166.3 Weights: [236.0, 89.5, 176.0, 166.3] Average weight: 166.95 Max weight: 236.00 (4) Prompt the user for a number between 1 and 4.

) Write list comprehensions to generate the following:i) If numlist contains a list of numbers, create a new list that contains only thosenumbers that are less than 100. (e.g. [42, 130, 7, 100, 101] becomes [42, 7])ii) The numbers from 3 to 30 that are multiples of 3 (i.e. 3, 6, 9, 12, 15... 30)iii) The numbers from 3 to 30 that are multiples of both 3 and 2 (i.e. 6, 12, 18...)iv) If wordlist contains a list of strings, create a new list that has the words that startwith “p” or “P”. (e.g. [“Apple”, “pear”, “avocado”, “Pumpkin”] becomes[“pear”,”Pumpkin”] )
8. Assume you already have a list defined, called numbers, containing only numericvalues. Write an expression that finds the product of the largest and smallest values in thelist. For example, if the list is [4, 1, 0.5, 10, 6], your expression would find the product of0.5 and 10
Python Code Create a code that can plot a distance versus time graph by importing matplotlib and appending data from a text file to a list. Follow the algorithm: Import matplotlib. Create two empty lists: Time = [ ] and Distance = [ ] Open text file named Motion.txt (content attached). Append data from Motion.txt such that the first column is placed in Time list and the second column is placed in Distance list. Plot the lists (Distance vs Time Graph). You may use this following link as a source for matplotlib functions: https://datatofish.com/line-chart-python-matplotlib/ Show Plot.
