2. 表格里part 1部分的informaiton about you里的street number and name, city,
state是填美国的地址还是填父母国内的地址？
3.Is this application based on an extension or change of status already

有python比较熟练的朋友帮忙看下这两道题吗？万分感激。。
Do both of these problems using at least one loop each and not using any
special pre-existing functions that give you the answer with just one line
of code.
1. Make a function to count the number of times a specified number is
repeated in a list/array. That means that if we have a number list
numberList=[5, 12, 0, 7, 2, 5, 10, 9, 12, 5];
and we use the function call
numRepeats(numberList, 5)
we get the output: 3 --- meaning 5 occurs three times in numberList.
2. Make a function that takes in a multi-dimensional array/list and returns
the "diagonal" --- a list of the elements at the 1st row-and-1st column, 2nd
row-and-2nd column, 3rd row-and-3rd column, etc. That means if we have a
multi-dimensional array:
multiArray = [[3, -4, 12, 5], [5, 2, 11, -5], [2, 2, 0, 5], [-5, -3, 2, 2]
];
and we use the function call
diagonal(multiArray)
we get the output [3, 2, 0, 2] .

第一个可以用dictionary，最后用value sort。
第二个用enumerate就可以做，或者map function

1 sum([1 for ele in numberList if ele == 5])
2 [ele[i] for i,ele in enumerate(inArray)]
