Python Coding challenge - Day 1295| What is the output of the following Python Code?

 

Code Explanation:

1. Importing median() and mean()

from statistics import median, mean

- The statistics module is a built-in Python module used for statistical calculations.

- median() calculates the median, which is the middle value of a sorted dataset.

- mean() calculates the arithmetic average of the given values.

2. Creating a List

x = [2, 4, 6, 8, 20]

- Creates a list named x containing five numbers.

- The values are already arranged in ascending order.

- This list will be used to calculate the median and mean.

3. Calculating the Median

a = median(x)

- The median() function finds the middle value of the dataset.

- Since the list contains five numbers, the third number is the middle value.

- Therefore, a = 6.

4. Calculating the Mean

b = mean(x)

- The mean() function calculates the average by adding all values and dividing by the number of values.

Calculation:

\[

\text{Mean}=\frac{2+4+6+8+20}{5}

=\frac{40}{5}=8

\]

- Therefore, b = 8.

5. Printing the Median and Mean

print(a, b)

- Prints the value stored in a, followed by the value stored in b.

- The values are separated by a space.

Output:

6 8

6. Comparing the Median and Mean

print(a < b)

- The < operator checks whether a is smaller than b.

- Here, Python evaluates 6 < 8.

- The condition is true, so Python prints True.

Final Output

6 8

True
