In the given example, we are printing different values like integer, float, string, and Boolean using print() method in Python.# printing integer value print(12) # printing float value print(12.56) # printing string value print("Hello") # printing boolean value print(True) ...
Example Print "YES!" if the function returns True, otherwise print "NO!": defmyFunction() : returnTrue ifmyFunction(): print("YES!") else: print("NO!") Try it Yourself » Python also has many built-in functions that return a boolean value, like theisinstance()function, which can ...
Python Booleans (bool)In Python, bool is a sub-type of int type. A bool object has two possible values, and it is initialized with Python keywords, True and False.Example>>> a=True >>> b=False >>> type(a), type(b) (<class 'bool'>, <class 'bool'>) ...
If you want to check multiple conditions in sequence, you can use multiple if, elif (else if), and else statements. In this way, we can make more complex decisions. Example: Using chained if-elif-else Code: x = -20 if x > 0: ...
Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. The following values are considered false: None False zero of any numeric type, for example, 0, 0L, 0.0, 0j. ...
To define a Boolean array in NumPy, we use the np.array() function and pass in a list of Boolean values. For example: import numpy as np arr_bool = np.array([1, 1.1, 0, None, 'a', '', True, False], dtype=bool) print(arr_bool) ...
Example# Logical NOT (not) operator x = True y = False # printing the values print("x: ", x) print("y: ", y) # 'not' operations print("not x: ", not x) print("not y: ", not y) Outputx: True y: False not x: False not y: True ...
