True — Expert Playground

Boolean literal representing true/1

Python Playground

# True is a singleton
a = bool(1)
b = True
c = bool("yes")
print(f"a is b: {a is b}")
print(f"a is c: {a is c}")

# Memory address is always the same
print(f"id(True): {id(True)}")
print(f"id(bool(1)): {id(bool(1))}")

# Bytecode for boolean operations
import dis
def check(x):
    if x:
        return True
    return False
dis.dis(check)

Click "Run" to execute your code

True and False are singletons — every True in your program is the exact same object. CPython interns them like small integers.

Challenge

Try modifying the code above to explore different behaviors. Can you extend the example to handle a new use case?
