This histogram will be drawn in a window thats is 500*500 and entitle it as “Histogram of chainlength”.For the y axis,The length of the longest chain plus some room for the labels at the bottom where n is shown.For the x axis, We want to show bars for 10 values and histograms look better if there is some space between the bars AND we’ll need some space on the left for the lengths to be printed. Let’s try 20.i want to have a range of 10 values and just let the user pick the starting value.want to allow the user to draw histograms for more than one range of numbers during the running of the program, we’ll want to close the window after having enough time to view it. You should close the window after 10 seconds. You’ll need to use sleep() to do this.All handling of the graphics window should be done within the drawHistogram() function.histogram should look like thishttp://www.cs.umbc.edu/courses/201/fall11/images/histo2.jpgplease i will need much help, i forever appreciate it.thanks in advance

I am working in Python and the question is for each person in the person list choose a number of friends (minimum is zero and maximum is size/200).  Assume this number is x.  Now you need to generate x locations of the friends and add them as friends to the list of friends of the current person.  The attached file shows that I have generated a random number using the random library.  However, how do I randomly select lines from the file and assign them to the friends list in the class.  I have attached both my code and the file I am using.

Once I complete this one, I will need to write a function that will sort the list by the number of friends in a descending order.  I think I have a function that will do that, but I am unable to test it, because I don’t think I am doing the first part correctly.  Then finally, for each person, I will need to find all people who have that person as a friend.  I think if I can figure out the first part, I can do the rest, but I am stuck on properly assigning friends.

I am not sure if I am doing this right.

Important refer to the paper that is attatched please!

Draw from the information gained in your first research paper and expand your research to follow up in a new paper. Write three to four (3-4) new pages that address the following:

1. Define presidential doctrine and summarize the regional or global events during the Cold War leading up to the formation of the presidential doctrine you wrote about in Assignment 1.  
2. Select one country you wrote about in Assignment 1 and describe the Cold War relationship that existed between the country you selected and the U.S. before the presidential doctrine was announced.
3. Describe the relationship that currently exists between the U.S. and the country you selected in section (2) above.
4. Describe the effect that the presidential doctrine has had on regional or global affairs since it was announced during the Cold War.
5. Assess whether the presidential doctrine you wrote about in Assignment 1 had had the intended effect of altering the behavior of the country you selected in section (2) above in the time since the doctrine was first announced.
6. Cite at least four (4) reputable sources in addition to the textbook, not including Wikipedia, encyclopedias, or dictionaries.

To help you understand this assignment further, the following description and examples may be useful.

Step 1: Define a doctrine and identify why a president would want to announce one. A doctrine is an ideological platform that a president uses to advance a policy towards a country or region in order to accomplish foreign policy goals for the United States, so you will need to expand on this theme. 

Refer back to Assignment 1 and build on whatever doctrine you wrote about then.  Say, for example, you selected the Truman Doctrine. Therefore, this is the only thing you will write about in Assignment 2 step 1.

Step 2: Select one country you wrote about in Assignment 1 and describe the Cold War relationship that existed between it and the U.S. before the presidential doctrine was announced. 

In the case of Truman, you would pick either the Soviet Union, Greece, or Iran, because all three were affected by his doctrine.  If you are writing about the Eisenhower Doctrine, you would choose Lebanon or Egypt; if you wrote about the Kennedy Doctrine, you would have write about Cuba or Vietnam; if your wrote about the Nixon Doctrine, you would choose either Vietnam, Saudi Arabia, or Iran; if you chose Carter, you would select either Iran or Afghanistan; and if you wrote about the Reagan Doctrine, you would select Nicaragua, Angola, Russia, or Afghanistan (although there were several others).

Step 3: Describe what effect the presidential doctrine you chose has had on regional or global affairs since it was announced during the Cold War. 

That is, how did the doctrine change the status quo regionally or globally after it was announced by the U.S.?  What happened in Western Europe after the Truman Doctrine was announced?  What happened in the Middle East after the Eisenhower Doctrine was announced?  What happened with Cuba or Vietnam after Kennedy offered up his doctrine of flexible response?  What happened in Southeast Asia or the Persian Gulf after the Nixon Doctrine went in effect?  What happened in the Middle East after the Carter Doctrine was announced?  What happened in Central America or Africa or the Middle East after Reagan announced his doctrine?

Step 4: Refer back to the country you selected in step two and describe the relationship that currently exists between the U.S. and that country. 

How has the relationship changed between the U.S. and that country since the doctrine was announced?

Step 5: Evaluate whether the presidential doctrine had had the intended effect of altering the behavior of the one country you selected in section (2) above since the doctrine was first announced.
