00:00 Introduction
00:34 PART1 - Pandas basics: Tubular data, Series & DataFrame
02:27 Install & import pandas
04:22 Series: 1d-list structure, with index
10:28 DataFrame: 2d-table structure, with index & columns
25:17 DataFrame - column: dot notation, fancy index, filter() by columns
30:33 DataFrame - column: new column, mean(), medium(), max(), idxmax(), update values, str functions
38:09 DataFrame - column: map() to update column data
41:31 DataFrame - column: drop() to a column
45:22 DataFrame - row: slice, filter() by rows
49:57 DataFrame - row: indexer - loc (label), iloc (position)
50:54 DataFrame - row: loc (label) indexer - df.loc[row, col]
57:15 DataFrame - row: iloc (position) indexer - df.iloc[row, col]
01:01:33 DataFrame - row: use boolean mask to retrieve records
01:05:10 DataFrame - row: query() to retrieve records
01:09:48 DataFrame - row: missing values handling
01:12:34 DataFrame - row: groupby() and agg()
01:15:27 DataFrame - row: groupby multiple columns VS pivot_table()
01:20:07 DataFrame - row: sort_values(), by multiple columns with different directions
01:22:24 PART 2 - Tips dataset: use pandas on a dataset
01:24:00 Tips Dataset: import packages & read tips dataset
01:28:58 SQL equivalent - SELECT: fancy index, filter(), loc, iloc
01:32:29 SQL equivalent - SELECT: with new column
01:33:37 SQL equivalent - WHERE: boolean mask, query()
01:35:17 SQL equivalent - WHERE multiple conditions: and, or
01:38:14 SQL equivalent - NULL handling: isnull(), isna(), notna()
01:39:26 SQL equivalent - GROUPBY: single field groupby, and apply agg functions
01:43:16 SQL equivalent - GROUPBY: multiple field groupby
01:44:23 SQL equivalent - JOIN: inner (intersection) / outer (union) - on='column', how='inner/outer'
01:47:33 SQL equivalent - JOIN: left (keep LHS) / right (keep RHS) - on='column', how='left/right'
01:49:08 SQL equivalent - UNION: pd.concat([ds1, ds2]).drop_doplicates()
01:50:21 SQL equivalent - UPDATE: df.loc, map()
01:53:07 SQL equivalent - DELETE: boolean mask method
01:56:05 Save DataFrame to a file
01:57:28 Plot graph - df.plot()
01:58:00 Summary & conclusion

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.

About YouTube 📺

YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟

Content and Users 🎵

Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.

While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.

Monetization and Impact 🤑

YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.

As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
