Loops:Nested loops are used to handle any spreadsheet-type set of data, in which the outer loop manages the rows while the inner loop manages the columns.Discuss the differences between while and for loops. Can you think of some examples of when a for loop would be the best structure to use?Also, discuss the number of times a loop executes may depend on a constant or on a variable that changeAn array is a collection of variables that are stored in order in consecutive positions in the computer's memory. Depending on the programming language, the array index starts at 0 (C language) or 1 (FORTRAN language); This item is stored in the position with the lowest address.Discuss the pros and cons of the use of arrays and parallel arrays and provide an example of a real-life equivalent to an array and a parallel array.Discuss what are the steps to verify that an item number exists in an array? Provide an example.Discuss the improvement in efficiency that can be realized by exiting a search loop when a match is found. Provide an example.

Using a new Jupyter notebook, analyze the partial list of Titanic passengers (titanic.csv (Links to an external site.)) with pandas.Answer the following three questions:What was the average cost in U.S. dollars of a first-class ticket? (See Note 1.)How many passengers over 20 had siblings onboard? (See Note 2.)What was the median age of those who did not survive?Then, create and answer three additional questions using the Titanic passengers' data.Create the following three graphs and three additional graphs of your own choice using matplotlib. Use colors to enhance your graphs.Use a pie chart to show the number of males and females.Use a bar chart to show the count of male survivors and the count of female survivors.Use a bar chart to show the count of each age.Note 1: Use £1.00 British pound = $1.28 U.S. dollars.Note 2: The dataset contains two fields that have mixed data: The Siblings/Spouse Aboard and the Parents/Children Aboard. Use the age of 20 as the threshold for differentiating the data in both fields. For example, if the age is 19, then interpret the number in Siblings/Spouse Aboard as siblings aboard. But if the age is 20, then interpret the number as spouse aboard unless the number is greater than 1, then interpret the number as siblings aboard.
