Convert a positive number to a Negative using min() Convert all positive numbers in a List to negative in Python #Convert a negative number to a Positive in Python Use theabs()function to convert a negative number to a positive, e.g.abs(number). Theabs()function returns the absolute val...
number_int = int(number_str)print(number_int) # 输出：123 在这个例子中，字符串 "123" 被转换为整数 123。示例和常见用例 基本字符串转换：str_to_int = int("456")print(str_to_int) # 输出：456 字符串中包含正负号：positive_int = int("+789")negative_int = int("-789")print(positive...
a boot symbol must be added. 0b for binary, 0o for octal, 0x for hexadecimal, and either case. The theoretical range of integer types is from negative infinity to positive infinity. The actual value is limited by the amount of computer memory...
下面是一个简单的单元测试示例:import unittestdef add(x, y):return x + yclass TestAdd(unittest.TestCase):def test_add_positive(self):self.assertEqual(add(1, 2), 3)def test_add_negative(self):self.assertEqual(add(-1, -2), -3)def test_add_zero(self):self.assertEqual(add(0, 0),...

在这个示例中,如果num的值大于0,则会执行第一个if语句后面的代码块,输出"The number is positive.“;如果num的值不大于0,但小于0,则会执行elif语句后面的代码块,输出"The number is negative.”;如果num的值既不大于0,也不小于0,则会执行else语句后面的代码块,输出"The number is zero."。
return "Positive"else:return "Negative"print("This line is never reached.") # 不可达代码 return的应用 return语句在函数中的应用非常广泛，它可以用于：1. 返回计算结果 函数通常用于执行一些特定的计算或操作，并将结果返回给调用者。def calculate_sum(a, b):return a + b result = calculate_sum(10...
Float, or "floating point number" is a number, positive or negative, containing one or more decimals. Example Floats: x =1.10 y =1.0 z = -35.59 print(type(x)) print(type(y)) print(type(z)) Try it Yourself » Float can also be scientific numbers with an "e" to indicate the ...
The Python if-else statement should look familiar to you. Python has a neat “elif” keyword for if-else-if control structures, for example: XML Copy if n < 0: print "n is negative" elif n == 0: print "n equals zero" else: print "n is positive" Next, ...
