key = The desired key to lookup

value = The value to set or return

What exactly is a dictionary?

A real-life dictionary holds words and their meanings. As you can imagine, likewise, a Python dictionary holds key-value pairs. Also to be noted that they are Unordered and mutable.

How to create one ?

mydict = {}                #Empty dictionary
mydict = {'key' : 'value'} #Initialized dictionary
person = {'name':'xyz', 'age':

Built in Function for creating a dictionary: dict()

myperson = dict() #empty dictionary
myperson = dict(name="xyz", age=23) #here we have given value to dict function

# while using dict function we dont need quotes or colons.

Modifying a dictionary

myperson = dict(name="xyz", age=23) #creating a dict
myperson["email"] = "xyz@gmail.com" #adding email as key and its value to dict

Adding list to a dictionary

myperson['new_list'] = [1, 2, 3] #adding new_list as key and [1,2,3] as value

Adding Dictionary to a dictionary

myperson['new_dict'] = {'nested_dict': 1} #new_dict is the key and {'nested_dict': 1} is the value

To delete an item, delete the key from the dictionary

del myperson['email'] #here key is deleted

Iterating Over a Dictionary

Yes, we can iterate over dictionary. Such structures on which we can iterate are called ITERABLE and things which iterates, like 'i' in for loop, that 'i' is called ITERATOR(abstract explanation).

myperson = {'name':'xyz', 'age':23}

for key in myperson:
    print(key, myperson[key],sep=" : ")

# key is iterated , so key is iterator here

The items() method can be used to loop over both the key and value simultaneously

myperson = {'name':'xyz', 'age':23}

for key,values in myperson.items():
    print(key,values)

While the values() method can be used to iterate over only the values

myperson = {'name':'xyz', 'age':23}

for values in myperson.values():
    print(values)

PART 2 - SOON

First, you have to enable the Youtube API from the Google Cloud Platform.

Once you enabled this then do the following step

The credentials thing is used to Get the Youtube API for us.

Finally, we get our API key by following all these steps. Now let us understand what is youtube VIDEO_ID

The red part is the video_id of the Video that you want a transcript of.

Now all the steps are done let us look at the code.

# pip install google-api-python-client
# pip install youtube_transcript_api

from apiclient.discovery import build
from youtube_transcript_api import YouTubeTranscriptApi

api_key = "Secret Key"  # replace it with your API key
video_id = str(input("Enter the video id: "))  # replace it with your channel id
youtube = build('youtube', 'v3',developerKey=api_key)

try:
        responses = YouTubeTranscriptApi.get_transcript(
            video_id, languages=['en'])
        print('\n'+"Video: "+"https://www.youtube.com/watch?v=" +
              str(video_id)+'\n'+'\n'+"Captions:")
        for response in responses:
            text = response['text']
            print(text)
except Exception as e:
        print(e)
