How to Check the Ratio of List Elements to Total Data in Python?

Estimated read time 1 min read

To check the ratio of each element in a list to the total data in Python, you can follow these steps:

  1. Calculate the total sum of the list elements.
  2. Iterate through each element in the list and calculate its ratio to the total sum.
  3. Display the ratios.

Here’s an example code snippet that demonstrates this process:

def calculate_ratios(data_list):
    total_sum = sum(data_list)  # Calculate the total sum of the list elements
    
    ratios = []
    for element in data_list:
        ratio = element / total_sum  # Calculate the ratio of each element to the total sum
        ratios.append(ratio)
    
    return ratios

# Example usage
data = [10, 20, 30, 40, 50]
ratios = calculate_ratios(data)
print(ratios)

In this example, the calculate_ratios function takes a list (data_list) as input. It calculates the total sum of the list elements using the sum() function. Then, it iterates through each element in the list and calculates its ratio to the total sum by dividing the element by the total sum. The ratios are stored in the ratios list and returned by the function.

Finally, we call the calculate_ratios function with an example list [10, 20, 30, 40, 50], and print the resulting ratios.
