create dictionary python from two lists

>>> keys = ['a', 'b', 'c']
>>> values = [1, 2, 3]
>>> dictionary = dict(zip(keys, values))
>>> print(dictionary)
{'a': 1, 'b': 2, 'c': 3}

Convert two lists into a dictionary in Python

>>> students = ["Cody", "Ashley", "Kerry"]
>>> grades = [93.5, 95.4, 82.8]
>>> {s: g for s, g in zip(students, grades)}

create dict from two lists

keys = ['a', 'b', 'c']
values = [1, 2, 3]
dictionary = dict(zip(keys, values))

merge a list of dictionaries python

>>> from collections import ChainMap
>>> a = [{'a':1},{'b':2},{'c':1},{'d':2}]
>>> dict(ChainMap(*a))
{'b': 2, 'c': 1, 'a': 1, 'd': 2}

python merge list of dict into single dict

l = [{'a': 0}, {'b': 1}, {'c': 2}, {'d': 3}, {'e': 4, 'a': 4}]
d = {k: v for x in l for k, v in x.items()}
print(d)
# {'a': 4, 'b': 1, 'c': 2, 'd': 3, 'e': 4}

Converting Two Lists Into a Dictionary

column_names = ['id', 'color', 'style']
column_values = [1, 'red', 'bold']

# Convert two lists into a dictionary with zip and the dict constructor
