Write A Python Function To Multiply All The Numbers From 1 To 5

Loops are fundamental building blocks in Python, allowing us to repeat a set of instructions multiple times. In the context of multiplying numbers, we utilize loops to iterate through a sequence of numbers, performing multiplication with each element.

 

The For Loop:

The for loop is the most intuitive and commonly used loop construct. It iterates through a sequence of elements, assigning each element to a variable within the loop body. Here's how we can use a for loop to multiply numbers from 1 to 5:

Python

def multiply_numbers_for():
  """
  This function multiplies all numbers from 1 to 5 using a for loop.
  """
  product = 1
  for number in range(1, 6):
    product *= number
  return product

result = multiply_numbers_for()
print(f"The product of numbers from 1 to 5 is: {result}")

This code snippet demonstrates a basic for loop implementation. We initialize a variable product to 1 and iterate through the range of numbers (1 to 5). Within the loop, we multiply each number with the current product and store the updated value. Finally, the function returns the final product.

 

The While Loop:

While loops offer greater control over iteration compared to for loops. They rely on a conditional statement to determine when the loop should terminate. Here's how we can rewrite the previous example using a while loop:

Python

def multiply_numbers_while():
  """
  This function multiplies all numbers from 1 to 5 using a while loop.
  """
  product = 1
  index = 1
  while index <= 5:
    product *= index
    index += 1
  return product

result = multiply_numbers_while()
print(f"The product of numbers from 1 to 5 is: {result}")

This code snippet utilizes a while loop with an index variable to iterate through the range. The loop continues until the index exceeds the final number (5). This approach offers flexibility in implementing custom loop termination conditions.
