Chaining of comparison operators
Comparison operations in python can be chained together. They can be used to check if a number is within a range, if 3 numbers are not equal to each other, etc.
if 10 <= a <= 20: # Equivalent to 10 <= a and a <= 20
print('variable is in [10; 20] range')
print('Great!')
if a != b != c: # Equivalent to a != b and b != c
print('b is different from both a and c')Challenge
Given the age of a person, we would like to know what would be their stage of life:

5-12 | Child |
13-19 | Teen |
20-39 | Adult |
40-59 | Middle Age Adult |
60+ | Senior Adult |
Input is given as a single integer number. Print the stage of life of that person.
Input | Output |
