我有 2 個列表：keys = ['p', 'e']
vals = [['p1', 'p2', 'p3'], ['e1', 'e2', 'e3']]如何迭代它們以創建這樣的字典列表：result = [{'p':'p1', 'e':'e1'}, {'p':'p2', 'e':'e2'}, {'p':'p3', 'e':'e3'}]

keys = ['p', 'e']
vals = [['p1', 'p2', 'p3'], ['e1', 'e2', 'e3']]
list_of_dicts = [ { keys[0]: val1, keys[1]: val2} for val1, val2 in zip(vals[0], vals[1]) ]
print(list_of_dicts)
編輯：
在一般情況下：
keys = ['p', 'e', 'z']
vals = [['p1', 'p2', 'p3'], ['e1', 'e2', 'e3'], ['z1', 'z2', 'z3']]
list_of_dicts = []
# spread vals array
for values in zip(*vals):
temp_dict = {}
for key, val in zip(keys, values):
temp_dict[key] = val
list_of_dicts.append(temp_dict)
print(list_of_dicts)
印刷：
[{'p': 'p1', 'e': 'e1', 'z': 'z1'}, {'p': 'p2', 'e': 'e2', 'z': 'z2'}, {'p': 'p3', 'e': 'e3',
'z': 'z3'}]
