make a dictionary from lists

I have following lists.

keys = ["key1", "key2", "key3"]

value1 = [1,2]
value2 = [10,20]
value3 = [100,200]

How can I get the result like [{"key1":1, "key2":10, "key3":100},{"key1":2, "key2":20, "key3":200}] using python?

I tried for loops but I couldn't find any solution.

Thanks in advance

You can do this by using for loop. Like this

keys = ["key1", "key2", "key3"]

value1 = [1,2]
value2 = [10,20]
value3 = [100,200]
values = [value1, value2, value3]
output = [{}, {}]

for i in range(len(keys)):
    output[0][keys[i]] = values[i][0]
    output[1][keys[i]] = values[i][1]

print(output)

Output

[{'key1': 1, 'key2': 10, 'key3': 100}, {'key1': 2, 'key2': 20, 'key3': 200}]

You can use a list comprehension to first zip your values elementwise, then create dictionaries by zipping those against your keys.

>>> [dict(zip(keys, i)) for i in zip(value1, value2, value3)]
[{'key1': 1, 'key2': 10, 'key3': 100}, {'key1': 2, 'key2': 20, 'key3': 200}]
