↓ Code Available Below! ↓ • This video shows how to concatenate data frames using the pandas library in Python. Data frame concatenation, also known as pasting or binding, just means joining together two data frames that have either the same columns or the same rows. In other words, using concatenate lets you add more rows or columns to an existing data frame. Concatenation should not be confused with join (merge) operations that involve combining the records of two data tables based on one or more shared key columns. • If you find this video useful, like, share and subscribe to support the channel! • ► Subscribe: https://www.youtube.com/c/DataDaft?su... • • Code used in this Python Code Clip: • import pandas as pd • data = pd.DataFrame({ character : [ Goku , Vegeta , Nappa , Gohan , Piccolo ], • power level : [12000, 16000, 4000, 1500, 3000]}) • data • new_rows = pd.DataFrame({ character : [ Tien , Yamcha , Krillin ], • power level : [2000, 1600, 2000]}) • new_rows • Concatenate Data Frames by Rows • data2 = pd.concat([data, new_rows], # List of data Frames to concatenate • axis=0, # Axis = 0 to concat by row • ignore_index=True) • data2 • new_cols = pd.DataFrame({ uniform color : [ orange , blue , black , orange , • purple , green , orange , orange ], • species :[ saiyan , saiyan , saiyan , half saiyan , • namak , human , human , human ]}) • new_cols • Concatenate Data Frames by Columns • pd.concat([data2, new_cols], # List of data Frames to concatenate • axis=1) # Axis = 1 to concat by column • • Note: YouTube does not allow greater than or less than symbols in the text description, so the code above will not be exactly the same as the code shown in the video! I will use Unicode large ＜ and ＞ symbols in place of the standard sized ones. . • • ⭐ Kite is a free AI-powered coding assistant that integrates with popular editors and IDEs to give you smart code completions and docs while you’re typing.
