如何在 Python 中逐行打印字典值？

Question

這是我的字典

使用 for 循環我打印這樣的值

for key in res.iterkeys():
  print key

for value in res.itervalues():
  print value

我需要這個作為輸出

我剛開始學字典請幫忙

Answer 1

# iterate the dictionary with the key and val at the same time
for key, val in res.items():
    # print the key
    print key
    for x in val:
    # iterate the list of the val and print all items
        print x

Answer 2

您正在嘗試在列表為值的字典中打印所有值。 我們這樣做的方式是：

for key in my_dict:
    print key
    for list_value in my_dict[key]:
        print list_value

1. 遍歷字典中的鍵
2. 打印密鑰
3. 遍歷在my_dict[key]找到的列表
4. 打印每個值。

Answer 3

好吧，如果您將字典稱為a，則可以執行以下操作：

for i in a:
    print(i)
    for j in a[i]:
        print(j)

如果您使用的是python 2.x，則可以在打印時刪除括號

Answer 4

考慮到您對字典的輸入是key:[list of values] 。 下面的代碼應該能夠實現您正在尋找的 -

dictionary = {'a': [1,2], 'b': [3,4], 'c':[5,6,7,8]}
for key,value in dictionary.items():
    print(key, ':', value)

輸出將是（鍵將不按特定順序打印） -

b : [3, 4]
c : [5, 6, 7, 8]
a : [1, 2]
