6. Comparison operations
Comparison operators are used to compare two values.
Comparison operations are useful to test variable values in conditional statements or loops.
Here are some examples of comparisons written in English::
score is greater than 100 name equals “Harry” acceleration is not equal to 0
Rewriting the comparisons above in Python would be.
score > 100
name == "Harry"
acceleration != 0
Comparison Operator |
Meaning |
---|---|
== |

< |
Less than |
<= |

Examples of comparisons in Python:
# score is greater than 10
score = 40
print(score > 10)
# name equals "Anne"
name = "Anne"
print(name == "Anne")
# speed is not equal to 0
speed = 2
print(speed != 0)
a = 7
b = 3
print(f'{a} == {b} is {a == b}') # 7 == 3 is False
print(f'{a} != {b} is {a != b}') # 7 != 3 is True
print(f'{a} > {b} is {a > b}') # 7 > 3 is True
print(f'{a} < {b} is {a < b}') # 7 < 3 is False
print(f'{a} >= {b} is {a >= b}') # 7 >= 3 is True
print(f'{a} <= {b} is {a <= b}') # 7 <= 3 is False
