如何拆分字符串并转换为整数

Question

numbers = "51-52"
for st in numbers:
    part = st.split("-")
    print(part)

到目前为止，这是我的代码。

我的成绩：['5'] ['1'] [''，''] ['5'] ['2']

预期：[ '51'] [ '52']

Answer 1

因为它应该只是：

numbers = "51-52"
print numbers.split("-")

Answer 2

for st in numbers将遍历字符串中的每个字符，因此您最终会在结果集中将每个字符分开。把它留下来，只需

numbers = "51-52"
parts = numbers.split("-")
print(parts)

Answer 3

numbers = "51-52"
part = [int(x) for x in numbers.split("-")]
print(part)
