Prompt Detail:
Python Membership Operators are used to test whether a value is a member of a sequence, such as a list, tuple, or string. They return True
if the value is a member of the sequence, and False
otherwise.
Here's a table that summarizes the different membership operators in Python:
Operator | Example | Description |
---|---|---|
in | x in y | Returns True if x is a member of the sequence y . |
not in | x not in y | Returns True if x is not a member of the sequence y . |
And here's a brief explanation of each membership operator with a coding example:
in
operator: This operator returnsTrue
if the left operand is a member of the sequence on the right.
makefilex = 3
y = [1, 2, 3, 4, 5]
result = x in y
print(result) # True
not in
operator: This operator returnsTrue
if the left operand is not a member of the sequence on the right.
makefilex = 6
y = [1, 2, 3, 4, 5]
result = x not in y
print(result) # True
In the second example, even though 6
is not a member of the list y
, not in
operator returns True
because 6
is not in the list.
