Python - unsupported operand type(s) for %: 'list' and 'int'
提问by BubbleMonster
I've had a look at other questions on stackoverflow but they are different and don't seem to apply to this question, so here goes.
我看过有关 stackoverflow 的其他问题，但它们是不同的，似乎不适用于这个问题，所以在这里。
I've written a simple script that gives me a print out of every number between 1-49 and puts it into a list using the range function.
我编写了一个简单的脚本，它打印出 1-49 之间的每个数字，并使用 range 函数将其放入列表中。
Now I have defined a function to work out what numbers are odd and what numbers are even, here is my code:
现在我已经定义了一个函数来计算哪些数字是奇数，哪些数字是偶数，这是我的代码：
def check(number):
if number%2==0:
print "Even Numbers:",(number)
else:
print "Odd Numbers:",(number)
a = range(1,50)
print a
check(a)
I get the following error when I run the script:
运行脚本时出现以下错误：
unsupported operand type(s) for %: 'list' and 'int'
So I know that this means the % operator cannot doesn't support 'lists' or 'ints', but how can I fix it?
所以我知道这意味着 % 运算符不能不支持“列表”或“整数”，但我该如何解决？
I tried this:
我试过这个：
def check(number):
if number%2==0:
print "Even Numbers:",(number)
else:
print "Odd Numbers:",(number)
a = range(1,50)
b = str(a)
check(str(a))
But get the error:
但得到错误：
Traceback (most recent call last):
File "showEvenNumbers.py", line 12, in <module>
check(str(a))
File "showEvenNumbers.py", line 2, in check
if number%2==0:
TypeError: not all arguments converted during string formatting
So I'm a bit unsure what to do.
所以我有点不确定该怎么做。
Any help would be much appreciated.
任何帮助将非常感激。

ais a list, but checkexpects a single integer. You need to iterate over the list:
a是一个列表，但check需要一个整数。您需要遍历列表：
for item in a:
check(item)
