numbers = [1, 2, 3, 4, 5] for num in numbers: if num % 2 == 0: print(num, "is even") else: print(num, "is odd") 在这个例子中,if 语句用于检查 num 是否为偶数。 四、布尔值在逻辑运算中的应用 布尔值支持常见的逻辑运算符,例如 and、or、not。 1. and 运算
下面是一个示例,演示了如何使用布尔转整数来统计列表中满足特定条件的元素个数。 numbers=[1,2,3,4,5,6,7,8,9,10]is_even=[num%2==0fornuminnumbers]# [False, True, False, True, False, True, False, True, False, True]count_even=sum(int(is_even))# 5print(count_even) 1. 2. 3. 4...
Python >>> import math >>> def is_prime(n): ... if n <= 1: ... return False ... for i in range(2, int(math.sqrt(n)) + 1): ... if n % i == 0: ... return False ... return True ... >>> # Work with prime numbers only >>> number = 3 >>> if...
Python Booleans - Learn about Python Booleans, including true and false values, and how to use them in your programs effectively.
Numbers, Booleans and NoneIn this chapter we will explore the different ways that numbers can be represented by the built-in types in Python. We will also introduce the Boolean type used to represent True and False. As part...doi:10.1007/978-3-030-20290-3_5John Hunt...
# Bitwise NOT (~) operator x = True y = False # printing the values print("x: ", x) print("y: ", y) # '~' operations print("~ x: ", ~ x) print("~ y: ", ~ y) # assigning numbers x = 123 y = 128 # printing the values print("x: ", x) print("y: ", y) #...
numbers are always True unless for the number 0 strings are False only when empty lists, tuples, sets, dictionaries are False only when emptyYou can check if a value is a boolean in this way:done = True type(done) == bool #True...
Python example to print different values: Here, we are going to learn how can we print different types of values using print() method in Python?ByPankaj SinghLast updated : April 08, 2023 Printing integer, float, string and Boolean using print() ...
#Convert Integers to Booleans in Python Use thebool()class to convert the numbers 1 and 0 to boolean values. Thebool()class will returnTruewhen converting 1 to a boolean andFalsewhen converting 0 to a boolean. main.py # ✅ convert 1 and 0 to boolean valuesresult=bool(1)print(result...
We do not specify the data type explicitly; Kotlin uses type inference to get the appropriate data type. It is String in our case. val male: Boolean = Random.nextBoolean() The Random class is used to produce random numbers. The nextBoolean method returns randomly a boolean value. ...
