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 setOutput
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
