TypeError: '<' not supported between instances of 'NoneType' and 'NoneType'
任务 4：在循环中从用户获取十个数字并找到最大的数字
List = []
for i in range(1, 11):
List.append(print(int(input("仅输入整数值::"))))
a = List[0]
for x in range(10):
if a < List[x]:
print(a, "是最大的数字")

List.append(print(int(input("Enter only integer value::"))))
a= List[0]
for x in range(10):
if a < List[x]:
print(a, "Is the largest number")

print() 总是返回 None。所以你的列表包含了许多 None 值。
input() 负责打印提示，所以你不需要 print()。
修改你的附加循环以去掉 print()：
List.append(int(input("只输入整数值：")))
英文:
print() always returns None. So your List contains a bunch of None values.
input() takes care of printing the prompt, so you don't need print() anyway.
Change your append loop to take out the print():
List.append(int(input("Enter only integer value::")))

你的输入中有一个像@JohnGordon所说的打印。你还需要遍历a。你目前只通过索引测量了你的list中的第一个值。
英文:
You have a print inside your input like @JohnGordon said. You also have to iterate through a. You are currently only measuring the 1st value in your list by indexing.
