Evaluate Values and Variables

You can evaluate any value and give you True or False in return.

Every value in Python is either True or False, numbers are True if they are not zero, and other values are True if they are not empty.

print(bool("Hello"))
print(bool(5))

num = 0
print(bool(num))

Output:

True
True
False

Any list, tuple, set, and dictionary is True, except empty ones.

print(bool("abc"))
print(bool(123))
print(bool(["A", "B", "C"]))

Output:

True
True
True
