Booleans in Python: Unveiling Truths
In Python, Booleans are a fundamental data type representing truth values, either True or False. Booleans play a crucial role in control flow, decision-making, and logical operations within your programs. Let's explore the key aspects of Booleans in Python :
1. Literal Values :
- Booleans have two literal values: True and False.
# Example
a = Trueb = False
2. Comparison Operators :
- Booleans often result from comparisons using operators like ==, !=, <, >, <=, and >=.
# Example
result = 5 > 3 # This evaluates to True
3. Logical Operators :
- Logical operators such as and, or, and not manipulate Booleans in compound expressions.
# Example
expression = (x > 0) and (y < 10 ) # True if both conditions are true
4. Truthy and Falsy Values :
- Certain values are treated as True or False in Boolean contexts. For example, 0 and an empty string ('') are considered False.
# Example
value = 0is_true = bool(value) # This evaluates to False
5. Boolean Functions :
- Built-in functions like bool() can explicitly convert values to Booleans.
# Example
result = bool(42) # This evaluates to True
