Truthy in Python

Last Updated : 18 Dec, 2024

In Python Programming, every value is either evaluated as True or False. Any value that is evaluated as a True boolean type is considered Truthy. The bool() function is used to check the Truthy or Falsy of an object. We will check how Python evaluates the truthiness of a value within a conditional statement.

Python

a = True
if a:
  print("GeeksforGeeks")

Output

GeeksforGeeks

Explanation:

In this example, the variable a is set to True, hence it is a Truthy value.

Constant Values

Non-zero Numbers

Any number that isn't zero is considered truthy. This includes positive and negative integers and floating-point numbers.

Python

a = 10
print(bool(a))

b = 10.50
print(bool(b))

Output

True
True

Non-empty Sequences

A sequence in Python ( string, list, dictionary, tuple or set) is Truthy when the length of a sequence if greater than or equal to one. In other words the sequence should not be empty.

Python

# string
s = "GFG"
print(bool(s))

# list
l = [1, 2, 3]
print(bool(l))

# dictonary
d = {1: "Apple"}
print(bool(d))

# tuple
t = (1, 2, 3, 4, 1)
print(bool(t))

#set 
s = {1, 2, 3}  
print(bool(s))

Output

True
True
True
True
True

Constant Values

The boolean constant True, as the name suggests is a Truthy value in Python.

Python

a = True
print(bool(a))

Output

True

re.search() in Python

re.search() method in Python helps to find patterns in strings. It scans through the entire string and returns the first match it finds. This method is part of Python's re-module, which allows us to work with regular expressions (regex) simply. Example:Pythonimport re s = "Hello, welcome to the worl

f-strings in Python

Python offers a powerful feature called f-strings (formatted string literals) to simplify string formatting and interpolation. f-strings is introduced in Python 3.6 it provides a concise and intuitive way to embed expressions and variables directly into strings. The idea behind f-strings is to make

re.match() in Python

re.match method in Python is used to check if a given pattern matches the beginning of a string. Itâ€™s like searching for a word or pattern at the start of a sentence. For example, we can use re.match to check if a string starts with a certain word, number, or symbol. We can do pattern matching using

Python True Keyword

True is a built-in Boolean value that represents truth or logical true value. It is one of the two Boolean constants (True and False) and is often used in conditions, loops and logical operations.Python treats True as 1 when used in arithmetic operations and as a truthy value in conditional statemen

Data Structures are a way of organizing data so that it can be accessed more efficiently depending upon the situation. Data Structures are fundamentals of any programming language around which a program is built. Python helps to learn the fundamental of these data structures in a simpler way as comp

Ternary Operator in Python

The ternary operator in Python allows us to perform conditional checks and assign values or perform operations on a single line. It is also known as a conditional expression because it evaluates a condition and returns one value if the condition is True and another if it is False.Basic Example of Te

type() function in Python

The type() function is mostly used for debugging purposes. Two different types of arguments can be passed to type() function, single and three arguments. If a single argument type(obj) is passed, it returns the type of the given object. If three argument types (object, bases, dict) are passed, it re

A string is a sequence of characters. Python treats anything inside quotes as a string. This includes letters, numbers, and symbols. Python has no character data type so single character is a string of length 1.Pythons = "GfG" print(s[1]) # access 2nd char s1 = s + s[0] # update print(s1) # printOut

re.findall() in Python

re.findall() method in Python helps us find all pattern occurrences in a string. It's like searching through a sentence to find every word that matches a specific rule. We can do this using regular expressions (regex) to create the pattern and then use re.findall() to get a list of matches.Let's say

Python string length

The string len() function returns the length of the string. In this article, we will see how to find the length of a string using the string len() method.Example:Pythons1 = "abcd" print(len(s1)) s2 = "" print(len(s2)) s3 = "a" print(len(s3))Output4 0 1 String len() Syntaxlen(string) ParameterString:
