print (T201)

Derived from the flake8-print linter.

Fix is sometimes available.

What it does

Checks for print statements.

Why is this bad?

print statements are useful in some situations (e.g., debugging), but should typically be omitted from production code. print statements can lead to the accidental inclusion of sensitive information in logs, and are not configurable by clients, unlike logging statements.

Example

def add_numbers(a, b):
    print(f"The sum of {a} and {b} is {a + b}")
    return a + b

Use instead:

def add_numbers(a, b):
    return a + b

Fix safety

This rule's fix is marked as unsafe, as it may remove print statements that are used beyond debugging purposes.
