方法一:使用循环和内置函数map() numbers=['123','456','789']int_list=list(map(int,numbers))print(int_list) 1. 2. 3. 示例输出: [123, 456, 789] 1. 方法二:使用列表推导式 numbers=['123','456','789']int_list=[int(num)fornuminnumbers]print(int_list) 1. 2. 3. 示例输出: [12...
2.4 步骤4:对平方后的list进行求和操作 对于求和操作,Python提供了一个内置函数sum(),可以对一个list中的所有元素进行求和。下面是相应的代码: sum_of_squared_numbers=sum(squared_numbers) 1. 在上述代码中,我们使用sum()函数对squared_numbers中的所有元素进行求和,并将结果保存在sum_of_squared_numbers变量中。
In this third and final example, we will use Python’s NumPy library to convert the list of floats to integers. First, though, we will need to install and import NumPy.# install numpy pip install numpy # import numpy import numpy as npNext, we will use np.array() function to convert...
