import math print("The square root of 16 is " + str(math.sqrt(16))) 在上面的代码中,我们首先定义了一个名为add_numbers的函数,用于计算两个数的和。然后,我们调用这个函数并打印出结果。接下来,我们导入了Python标准库中的math模块,并使用其中的sqrt函数计算了16的平方根。通过函数和模块的应用,我们可以...

We will simply convert the number into string and then using reversed(string) predefined function in python ,we will check whether the reversed string is same as the number or not. Algorithm/Steps The following are the algorithm/steps to print Palindrome numbers from the givenPython list: ...

# If the size is a square you can only specify a single number x = F.max_pool2d(F.relu(self.conv2(x)), 2)#再经过一个conv->relu->maxpool层 x = x.view(-1, self.num_flat_features(x))#改变上层输出的shape,保留第一个维度的值,把x变为2维的,因为全连接层必须要2维的输入?
In this example, theis_primefunction checks if a number is prime by testing divisibility from 2 up to the square root of the number. Theprint_primesfunction iterates from 2 to N and prints the prime numbers. I executed the above Python code, and you can see the output in the screensho...
