检查数字列表中是否存在数字
问题描述：
如何查看索引中是否包含某些数字？
How can I see if an index contains certain numbers?
numbers = [2349523234, 12345123, 12346671, 13246457, 134123431]
for number in numbers:
if (4 in number):
print(number + "True")
else:
print("False")
答
您必须对以下内容进行字符串比较此
You would have to do string comparisons for this
for number in numbers:
if '4' in str(number):
print('{} True'.format(number))
else:
print("False")
问数字 4 是否在另一个数字中并没有什么意义（除非您对 in有一些特殊的定义） ）
It isn't really meaningful to ask if the number 4 is "in" another number (unless you have some particular definition of "in" in mind)
