convert two lists to a single dictionary python
#initialize lists key_list = ['red', 'green', 'blue'] value_list = [1, 2, 3] #convert lists my_dict = {} for key in key_list: for value in value_list: my_dict[key] = value value_list.remove(value) break print(my_dict)
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}
merge two list of dictionaries python with string
import pandas as pd l1 = [{'id': 9, 'av': 4}, {'id': 10, 'av': 0}, {'id': 8, 'av': 0}] l2 = [{'id': 9, 'nv': 45}, {'id': 10, 'nv': 0}, {'id': 8, 'nv': 30}] df1 = pd.DataFrame(l1).set_index('id') df2 = pd.DataFrame(l2).set_index('id') df = df1.merge(df2, left_index=True, right_index=True) df.T.to_dict() # {9: {'av': 4, 'nv': 45}, 10: {'av': 0, 'nv': 0}, 8: {'av': 0, 'nv': 30}}
