如何解决 TypeError: 'int' object is not iterable？

Question

我想在这个程序中做的是，我尝试进行一些输入并检查它们是偶数还是奇数，然后打印出来。但是，当我运行它时，它显示以下错误消息 - （见下图）

for i in inp: TypeError: 'int' object is not iterable

源代码：

def number():
    n=int(input('How many numbers are there in your input: '))
    for inp in range(n):
        inp=eval(input('input= '))
    for i in inp:
        if i % 2 == 0:
            print(i, ' is even')
            continue
        else:
            print(i, ' is odd')
            continue
number()

Answer 1

您需要使用list 和append 输入。这样你以后可以迭代它。

 def number():
    n = int(input('How many numbers are there in your input: '))
    inp = []
    for i in range(n):
        p = input('input= ')
        if p.isdigit():
            inp.append(int(p))
    for i in inp:
        if i % 2 == 0:
            print(i, ' is even')
        else:
            print(i, ' is odd')

number()

Answer 2

def number():
  n=int(input('How many numbers are there in your input: '))
  inp = []
  for i in range(n):
    inp.append(int(input('input= ')))
  for i in inp:
    if i % 2 == 0:
        print(i, ' is even')

    else:
        print(i, ' is odd')

number()
