如何从整数列表中的元素 add/subtract

Question

我想先将列表的字符串转为整数，然后对所有元素加1，例如：

mylist = ["0", "1", "2"]
ints = [int(item) for item in mylist]
ints = ints+1
print(ints)

然后我希望输出为：

1, 2, 3

不确定我该怎么做，希望能提供一些帮助

Answer 1

像这样

mylist = ["0", "1", "2"]
ints = [int(item)+1 for item in mylist]

print(ints)

Answer 2

你可以使用 NumPy 来解决这个问题

import numpy as np
myList = ["0","1","2"]
myArray = np.array(myList, dtype=int) + 1
print(myArray)
