Question

Consider the following code:

c = 10
while (c > 5):
print ("Next number: " + str(c))
c = c - 1
It should print out:

Next number: 10
Next number: 9
Next number: 8
Next number: 7
Next number: 6

What is wrong?

Answer 1

The issue with the code is a lack of indentation, which is necessary for defining code blocks in Python. Once indentations are correctly applied to the print statement and the decrement operation, the while loop will function as expected.

Step-by-step explanation:

The provided code sample appears to have an indentation problem that may prevent it from working correctly. In Python, code blocks are defined by their indentation. Here is the corrected version of the provided code:

c = 10
while (c > 5):
print("Next number: " + str(c))
c = c - 1

Notice the indentation before both the print statement and the decrement operation c = c - 1. In Python, it is crucial to maintain consistent indentation to define the scope of the loop and other control structures correctly.

When this indentation is properly applied, the while loop executes as expected, and the code prints the numbers from 10 down to 6 in descending order. Once the variable c is no longer greater than 5, the loop terminates.

Answer 2

I just ran it on Visual Studio Code, there seems to be nothing wrong with it and I'm getting the expected output. Perhaps it's your indentation. - The fixed indentation is below:

c = 10

while (c > 5):

print ("Next number: " + str(c))

c = c - 1

That's all I can think of.
