Python Coding challenge - Day 224 | What is the output of the following Python Code?

 

Let's break down the code step by step:

cl = 4
while cl < 6:
    cl = cl + 1
    print(cl, end='-')

Explanation

1. Initialization:

   cl = 4

   Here, the variable cl is initialized to 4.

2. While Loop Condition:

   while cl < 6:   
3.  The while loop will continue to execute as long as the condition cl < 6 is True. Initially, cl is 4, so the condition is True.

4. Inside the Loop:

   cl = cl + 1
   
   Inside the loop, cl is incremented by 1. The first time this statement is executed, cl becomes 5.

5. Print Statement:

   print(cl, end='-')
   
   This prints the current value of cl followed by a hyphen -. The end='-' part ensures that the next output is printed immediately after the hyphen without moving to a new line.

Step-by-Step Execution

• Initial State:

  cl is 4.
  The while condition cl < 6 is checked and is True.

• First Iteration:

  cl = cl + 1 is executed, so cl becomes 5.
  print(cl, end='-') prints 5-.

• Second Iteration:

  The while condition cl < 6 is checked again. Now cl is 5, so the condition is still True.cl = cl + 1 is executed again, so cl becomes 6.
  print(cl, end='-') prints 6-.

• End of Loop:

  The while condition cl < 6 is checked once more. Now cl is 6, so the condition is False.
  The loop terminates.

Output

The output of this code will be:

5-6-

Each iteration of the loop increases the value of cl by 1 and prints it, followed by a hyphen. The loop stops running when cl reaches 6.
