# Python operator.truth() Function Example
import operator
print("operator.truth(True):", operator.truth(True))
print("operator.truth(False):", operator.truth(False))print()x = 1
print("x:", x)
print("operator.truth(x):", operator.truth(x))print()x = 10
print("x:", x)
print("operator.truth(x):", operator.truth(x))print()x = -10
print("x:", x)
print("operator.truth(x):", operator.truth(x))print()x = 0
print("x:", x)
print("operator.truth(x):", operator.truth(x))print()x = "Hello"
print("x:", x)
print("operator.truth(x):", operator.truth(x))print()x = ""
print("x:", x)
print("operator.truth(x):", operator.truth(x))print()输出：
