当我将列表转换为字符串时，为什么这会给我“TypeError：'int' 类型的参数不可迭代”

Question

Why is this giving me:

"TypeError: argument of type 'int' is not iterable"

when I converted the list to strings:

def giveMeFive (start, end):
    numbers = list(range(start,end))
    for x in numbers:
        [str(x) for x in numbers]
        if str(5) in x:
            return x

Answer 1

u can use this code

def giveMeFive (start, end):
    numbers = list(range(start,end))
    return numbers.index(5)

Answer 2

When you write [str(x) for x in numbers] all by itself, you are creating a new list of strings, and then immediately throwing it away. You have to save it in a variable to keep it.

Try

def giveMeFive (start, end):
    numbers = list(range(start,end))
    strings = [str(x) for x in numbers]
    for x in strings:
        if str(5) in x:
            return x

Now, there are more errors in your code, but hopefully this will get you unstuck.

Answer 3

更清楚地说，此代码旨在返回包含字符串“5”的特定范围内的所有数字。
