Write a loop that prints each country's population in country_pop. sample output with input: 'china:1365830000,india:1247220000,united states:31
There are many different ways to loop through a list of countries and their populations. One way to do this is with a for loop. For each country in the list, we can print out its population.
Here's an example of how this might look:
for country in country_pop:
print(country + ": " + str(country_pop[country]))
This would print out each country's population, like so:
China: 1365830000
India: 1247220000
United States: 310000000
As we can see, China and India have the two largest populations in the world. The United States, while still populous, is only about a third of the size of China.
There are a number of reasons for these population differences. One is simply historical. China and India have both been around for thousands of years, while the United States is a relatively new country. Another reason is geography. China and India are both large countries with a lot of land, while the United States is smaller and has less land area.

given two input integers for an arrow body and arrowhead (respectively), print a right-facing arrow.
To do this using two input integers for the arrow body and arrowhead (respectively).
First, let's start with the arrow body. We want this to be a solid line, so we'll use a for loop to print out a sequence of asterisks. Let's say the integer for the arrow body is 5. Our for loop would look like this:
for (int i=0; i<5; i++){
System.out.print("*");
}
Next, we'll move on to the arrowhead. This will be a bit more tricky, but we can still use a for loop. We want to print out a sequence of asterisks, but we also want the first asterisk to be in the middle of the arrow body. To do this, we can use a variable to keep track of the position of the first asterisk. Let's say the integer for the arrowhead is 3. Our for loop would look like this:
int headPos = (5-3)/2;
for (int i=0; i<3; i++){
System.out.print("*");
if (i == 0){
System.out.print(headPos);
}
}

Why was freshdesk a good candidate for remote computing services on the cloud? Freshdesk is a strong contender because it has expanded quickly in just four years. Since Freshdesk provides software as a service, moving its operations to the cloud rather than maintaining its internal infrastructure made more sense. Thousands of businesses today use Freshdesk as their customer support software, but Freshdesk itself depends on AWS to host and manage its software platform.
What was freshdesk’s experience working with aws? Working with AWS has allegedly been a very satisfying experience for Freshdesk. Krishnenjit Roy, the company's director of IT Operations, publicly acknowledged that he now felt like he was working with a business that was interested in lowering Freshdesk's cost and maximizing productivity.
What made amazon redshift and opsworks good fits for freshdesk?Redshift was a fantastic pick because of Freshdesk's scalability and connectivity with strong business intelligence tools. OpsWork also brought a blend of low-cost and customisation for Freshdesk, which made it the ideal match. Because they enable Freshdesk to create its own customer support apps while utilizing and maintaining them with Amazon's resources, both software packages are an excellent fit. Freshdesk's data is stored in Redshift, and its software applications are handled by Amazon OpsWorks. They are regarded as Freshdesk's core employees together.
