Learn ==, !=, <, >, <=, >= operators.
Comparison operators
Comparison operators compare two values and return a bool: == equal, != not equal, < less than, > greater than, <= less or equal, >= greater or equal.
print(5 == 5) # True
print(3 < 7) # True
print(10 != 10) # FalseThese operators are used in if conditions. The result is always True or False.
Chained comparison
Python supports chained comparison: 1 < x < 10. This is the same as 1 < x and x < 10 but more readable.
x = 5
print(1 < x < 10) # True
print(0 <= x <= 5) # TrueThis feature is absent in many other languages and is one of Python's readability wins.
Practice Print comparisons
Assign age = 18. Print print(age >= 18) and print(age < 21).
Starter code
# Do the comparisonSample solution
age = 18
print(age >= 18)
print(age < 21)Expected output
True True
