Python Coding challenge - Day 39 | What is the output of the following Python code?

 

The code is a simple Python while loop that starts with the variable cl set to 4. It increments cl by 1 in each iteration and prints the updated value of cl followed by a hyphen ("-") until cl is no longer less than 9. Here's the output of the code: 5-6-7-8-9-

The loop starts with cl equal to 4, and in each iteration, it increments cl by 1. When cl reaches 9, the loop stops because the condition cl < 9 is no longer true.

 step by step solutions 

Initialize the variable cl with the value 4:

cl = 4

Start a while loop with the condition cl < 9. This means the loop will continue as long as cl is less than 9.

Inside the loop, increment the value of cl by 1. This is done using the cl = cl + 1 statement:

cl = cl + 1

Print the updated value of cl, followed by a hyphen (-) without moving to the next line due to the end parameter:

print(cl, end='-')

The loop will continue to the next iteration or exit the loop depending on whether the condition cl < 9 is still true.

The loop repeats steps 3-5 until the condition cl < 9 is no longer true. When cl becomes equal to 9, the loop exits.

Here's the output produced by the code, showing each step:

Step 1: cl = 4

Step 2: Entering the while loop with the condition cl < 9 (4 < 9 is true)

Step 3: Incrementing cl by 1, cl is now 5

Step 4: Printing 5 with an end of '-', output so far: 5-

Step 2: Entering the while loop with the condition cl < 9 (5 < 9 is true)

Step 3: Incrementing cl by 1, cl is now 6

Step 4: Printing 6 with an end of '-', output so far: 5-6-

Step 2: Entering the while loop with the condition cl < 9 (6 < 9 is true)

Step 3: Incrementing cl by 1, cl is now 7

Step 4: Printing 7 with an end of '-', output so far: 5-6-7-

Step 2: Entering the while loop with the condition cl < 9 (7 < 9 is true)

Step 3: Incrementing cl by 1, cl is now 8

Step 4: Printing 8 with an end of '-', output so far: 5-6-7-8-

Step 2: Entering the while loop with the condition cl < 9 (8 < 9 is true)

Step 3: Incrementing cl by 1, cl is now 9

Step 4: Printing 9 with an end of '-', output so far: 5-6-7-8-9-

Step 2: Exiting the while loop as the condition cl < 9 is no longer true

The final output is 5-6-7-8-9-, which is the result of running the code.
