programming python

Hướng dẫn how do you find the sum of an odd number in an array in python? - làm thế nào để bạn tìm thấy tổng của một số lẻ trong một mảng trong python?

Điều này có thể được thực hiện với isinstance, điều này mạnh mẽ chống lại những thứ như các lớp con:

def _oddsum[n]:
    # efficient generator expression here
    return sum[i for i in range[n + 1] if i % 2 == 1]

def oddsum[arr]:
    return [_oddsum[n] for n in arr]

def polymorph_oddsum[x]:
    if isinstance[x, list]:
        return oddsum[x]
    return _oddsum[x]

if __name__ == "__main__":
    # really all of these are more sensible ways to do this
    print[oddsum[[9]]]
    print[_oddsum[9]]
    print[oddsum[[4, 5, 9]]]
    print[oddsum[[4, 5, 9]]]
    print[oddsum[{4, 5, 9}]]

    # but if you really wanted, you can use polymorph_oddsum for either case
    print[polymorph_oddsum[9]]
    print[polymorph_oddsum[[4, 5, 9]]]

Tuy nhiên, như bạn có thể thấy từ những bình luận của tôi, đây có lẽ thực sự không phải là điều bạn muốn làm. Bạn chỉ nên gọi chức năng thích hợp tùy thuộc vào loại đầu vào của bạn sẽ là gì, mà bạn thực sự nên biết trước khi chạy.

Cách tiếp cận isinstance ít được mong muốn hơn vì nó bị hỏng ngay khi bạn cho nó bất kỳ loại nào khác có thể khác, mặc dù oddsum bình thường không, như mã của tôi cho thấy.

Ngẫu nhiên, trong khi tôi đã tự do đưa vòng lặp của bạn vào một biểu thức máy phát duy nhất, bạn thậm chí không cần một vòng lặp ở đây. Tổng số lẻ là một tiến trình dễ dàng để tìm một biểu mẫu đóng cho và bạn chỉ có thể sử dụng

def _oddsum2[n]:
    return [[n + 1] // 2] ** 2

Điều kiện tiên quyết - cơ bản mảng & nbsp; đưa ra một mảng, viết một chương trình để tìm tổng các giá trị của các vị trí chỉ số chẵn và lẻ một cách riêng biệt.
Given an array, write a program to find the sum of values of even and odd index positions separately.

Examples: 

Input : arr = {1, 2, 3, 4, 5, 6}
Output :Even index positions sum 9
        Odd index positions sum 12
Explanation: Here, n = 6 so there will be 3 even 
index positions and 3 odd index positions in an array
Even = 1 + 3 + 5 = 9
Odd =  2 + 4 + 6 = 12

Input : arr = {10, 20, 30, 40, 50, 60, 70}
Output : Even index positions sum 160
        Odd index positions sum 170
Explanation: Here, n = 7 so there will be 3 odd
index positions and 4 even index positions in an array
Even = 10 + 30 + 50 + 70 = 160
Odd = 20 + 40 + 60 = 120
