使用for循环填充字典(python)

Question

我正在尝试使用for循环创建一个字典.这是我的代码:

dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
    for x in values:
        dicts[i] = x
print(dicts)

这输出:

{0: 'John', 1: 'John', 2: 'John', 3: 'John'}

为什么？

我打算把它输出:

{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

为什么不以这种方式输出,我们如何正确输出？

Answer 1

dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
        dicts[i] = values[i]
print(dicts)

或者

In [7]: dict(list(enumerate(values)))
Out[7]: {0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

Answer 2

>>> dict(zip(keys, values))
{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}
