While loop from 1 to infinity, therefore running forever. x = 1 while True: print("To infinity and beyond! We're getting close, on %d now!" % (x)) x += 1 · When running the above example, you can stop the program by pressing ctrl+c at the same time. As you can see, these loop constructs serve different purposes.

Here, print('Last statement') is outside the body of the loop. Therefore, this statement is executed only once at the end. If we iterate through a string, we get individual characters of the string one by one. language = 'Python' # iterate over each character in language for x in language: print(x)

3 weeks ago - In this example, color is the loop variable, while the colors list is the target collection. Each time through the loop, color takes on a successive item from colors. In this loop, the body consists of a call to print() that displays the value on the screen. This loop runs once for each item in the target iterable. The way the code above is written is the Pythonic way to write it.
