In programming, sometimes we want values to be either **True **or **False **which has assigned in programming as Boolean values.

We can compare two values directly which will return **True **or **False **accordingly as a **Boolean value**.

## Example

print(10 == 10) print(10 == 9) print(10 > 9) print(10 < 9)

## Output

True False True False

In Python, we use **bool()** function to check **True **or **False**.

**bool()** function always returns True until we don’t pass something from the following–

- 0
- empty string
- empty list, tuple, dictionary
- other empty objects like a set
- anything like a function which returns a function

## Example

print(bool(0)) # passing 0 print(bool("")) # passing an empty string print(bool([])) # passing an empty list print(bool({})) # passing an empty dict print(bool(())) # passing an empty set

## Output

False False False False False

**bool()** will return **True **if the value is not an empty one.

## Example

print(bool(1)) print(bool(12.2)) print(bool(23j)) print(bool("aString")) print(bool([1, 2, "Hello"])) print(bool({"Key":"value"}))

## Output

True True True True True True
