Boolean expressions use comparison operators (<, <=, >, >=, ==, !=) to evaluate conditions. Logical operators (and, or, not) combine or negate boolean expressions. The bool() function reveals that every Python value is either truthy or falsy — for example, 0 is False, non-zero numbers are True, empty strings are False, and non-empty strings are True. Boolean expressions are foundational to if statements and while loops. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### why does bool("False") return True in Python Because any non-empty string is truthy in Python, regardless of its content. The string "False" has characters in it, so bool("False") evaluates to True. Only an empty string, the number 0, and a few other empty or zero-like values evaluate to False when passed to bool(). _Developers debugging truthy/falsy surprises in Python can find quick explainers like this on daily.dev._ ### what is the difference between == and is when comparing values in Python This is not directly addressed, but the material clarifies that == and != check equality of values, including strings, comparing 'Alice' to 'alice' as unequal due to case sensitivity. For example, name1 == "Alice" returns True while name1 == "alice" returns False. _Anyone sorting out Python equality checks can keep learning resources handy on daily.dev._ ## Similar posts on daily.dev - [Python Operators and Expressions – Real Python](https://daily.dev/posts/python-operators-and-expressions-real-python-sijod8bcg) · Real Python · 2 upvotes · 0 comments - [Python 101 — Before Learning Python](https://daily.dev/posts/python-101-before-learning-python-ktrhtk3s1) · Medium · 1 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python) [View this post on daily.dev](https://daily.dev/posts/python-booleans-and-boolean-expressions-zodkkivgn) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Python Booleans and Boolean Expressions","url":"https://daily.dev/posts/python-booleans-and-boolean-expressions-zodkkivgn","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/python-booleans-and-boolean-expressions-zodkkivgn"},"datePublished":"2026-08-01T01:51:22.276Z","dateModified":"2026-09-14T08:59:41.519Z","description":"Python booleans can only hold two values: True or False.
