Comparison

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) # False

These 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)  # True

This feature is absent in many other languages and is one of Python's readability wins.

Exercise Print comparisons

Assign age = 18. Print print(age >= 18) and print(age < 21).

Show example solution

age = 18
print(age >= 18)
print(age < 21)

Test yourself

What is 5 != 5?
- True
- It raises an error
- 0
- False
Show answer

False — Since 5 equals 5, != gives False.
Equality check
```
print(10 ____ 10)
```
Show answer
```
print(10 == 10)
```
Match the operators

==

Equal
!=

Not equal
<

Less than
>=

Greater or equal
