Let me explain this code:
num = 1
while num < 6:
print(num)
This code has a few issues that would cause it to run indefinitely (infinite loop). Let me break down why and how to fix it:
First, num = 1 initializes a variable num with the value 1
The while loop continues executing as long as num < 6 is True
Inside the loop, print(num) prints the current value of num
However, the code is missing an increment statement to update num, so num will always stay 1 and the condition num < 6 will always be True
Here's the corrected version:
python num += 1 # Increment num by 1 in each iteration
num += 1 # Increment num by 1 in each iteration
This corrected version will:
1. Start with num = 1
2. Print: 1
3. Increment num to 2
4. Print: 2
5. Increment num to 3
6. Print: 3
7. Increment num to 4
8. Print: 4
9. Increment num to 5
10. Print: 5
11. Increment num to 6
12. Stop (because num < 6 is no longer True)
The output will be:
1
2
3
4
5
The key lesson here is that when using while loops, you need to make sure:
1. You have a proper condition that will eventually become False
2. You update the variables involved in the condition inside the loop
3. The loop has a clear way to terminate
