Loop in Python allows you to iterate anything inside the loop for a particular time. Most of the loops in Python are used as increment loops. But in this post, you will know how to Decrement a for Loop in Python with steps.
Steps to Decrement a for Loop in Python
To decrement a for loop in Python, you can follow these steps.
Step 1: Determine the starting and ending values for the loop. These values will define the range of iterations.
Step 2: Use the
range() function with useful parameters to set up the loop. The range() function provides a sequence of numbers that can be used in the loop.
Step 3: Specify a negative step value in the
range() function to ensure the loop variable is decremented at each iteration.
After step 3 just Write the code that needs to be executed within the loop block.
Below is a complete example of How to Decrease a Loop in Python
start_value = 20
end_value = 0
for i in range(start_value, end_value, -1):
print(i) # Print the value of i during each iteration
# Additional code to be executed within the loop block
In the above example, the loop start value contains the value that will start the loop and it will start at 20. And this loop will iterate until it reaches the end_value =0. The i value will be used to decrement the value of start_value in each iteration.
Most of the time the loops are iterative in an incremental way. But sometimes you have to use it in the decrement loop. The above steps are very simple to decrement a Loop in Python
