This recipe helps you unstack in python
Recipe Objective
While operating with dataframes, we might have stacked array or in simpler terms, single column to denote all rows and one other column containing all values. We can unstack this type of dataframe using unstack function.
So this recipe is a short example on how to unstack in python. Let's get started.
Step 1 - Import the library
import pandas as pd
import seaborn as sb
Let's pause and look at these imports. Pandas is generally used for performing mathematical operation and preferably over arrays. Seaborn is just for importing dataset for now.
Step 2 - Setup the Data
df = sb.load_dataset('tips')
print(df)
Here we have simply imported tips dataset from seaborn library and printed it.
Step 3 - Stacking the dataframe
df_stacked = df.stack()
print(df_stacked)
Here, we are stacked our array and finally printing it.
Step 4 - Unstacking the array
df_unstacked=df_stacked.unstack()
print(df_unstacked)
Here, we are unstacking our array and finally printing it.
Step 5 - Let's look at our dataset now
Once we run the above code snippet, we will see:
