How To Increment Python For Loop By Multiplication

Authors

In Python, you can use a for loop to iterate over a range of values and perform a set of operations on each iteration.

One common operation is to increment the loop variable by a certain amount in each iteration.

In this guide, we'll look at how to increment a loop variable by a multiple of its value in each iteration.

To do this, we can use the following approach:

start = 1
stop = 10
multiplier = 2

for i in range(start, stop+1):
  i *= multiplier
  print(i)

This code will print the following output:

2
4
8
16
32
64
128
256
512
1024

As you can see, the loop variable i is multiplied by multiplier in each iteration, resulting in an increment that is a multiple of the current value of i.

It's important to note that this approach modifies the value of i in each iteration.

If you want to keep the original value of i unchanged, you can use a separate variable to store the multiplied value:

start = 1
stop = 10
multiplier = 2

for i in range(start, stop+1):
  multiplied_i = i * multiplier
  print(multiplied_i)

This will produce the same output as the previous example, but the value of i will remain unchanged throughout the loop.

Summary

In summary, to increment a loop variable by a multiple of its value in each iteration in Python, you can use the following approach:

  • Set up a for loop to iterate over a range of values.
  • In the loop body, multiply the loop variable by the desired multiplier.
  • Use the multiplied value in your operations.

This simple technique can be useful in a variety of situations where you want to perform operations on a set of values that are related in some way.

Whether you're working with numbers, strings, or any other type of data, this technique can help you write efficient and effective code.
