Write a Python program that uses the math module to calculate the natural logarithm of a user input number. The function natural_log(n) should return the natural logarithm of n.
Example 1:
Input: natural_log(20) Output: 2.995732273553991
Example 2:
Input: natural_log(7) Output: 1.9459101490553132
Use the math.log() function from the math module.
import math
def natural_log(n):
return math.log(n)
# Test the function
print(natural_log(20))
print(natural_log(7))
