How to use keys() In Python
After iterating to a list the keys from the dictionary can further be extracted using the keys() function.
Example: Extracting key values
Python3
# Create a list of dictionarieslanguages = [ { "Python": "Machine Learning", "R": "Machine learning", }, { "Python": "Web development", "Java Script": "Web Development", "HTML": "Web Development" }, { "C++": "Game Development", "Python": "Game Development" }, { "Java": "App Development", "Kotlin": "App Development" }]# iterate over the listfor i in languages: # now i is a dict, now we see the keys # of the dict for key in i.keys(): # print every key of each dict print(key) print("-------------") |

List of dictionaries in use:
[{‘Python’: ‘Machine Learning’, ‘R’: ‘Machine learning’},
{‘Python’: ‘Web development’, ‘Java Script’: ‘Web Development’, ‘HTML’: ‘Web Development’},
{‘C++’: ‘Game Development’, ‘Python’: ‘Game Development’}, {‘Java’: ‘App Development’, ‘Kotlin’: ‘App Development’}]
