Here, we’re going to retrieve and print out theindex: print(sales_data.index) OUT: RangeIndex(start=0, stop=11, step=1) Notice that when we do this, the code returns aRangeIndexobject. This is really just a sp
By using DataFrame.iloc[] property you can get the row by Index.# Get Row by Index. print(df.iloc[2]) # Output: # Courses Hadoop # Fee 26000 # Duration 35days # Discount 1500 # Name: idx3, dtype: object 7. Set Labels to Index...
What does the row count in DataFrame shape signify? The row count in DataFrame shape signifies the number of observations or records present in the DataFrame. Each row typically represents a single observation or data point in the dataset. Therefore, the row count indicates the total number of ...

So there are 2 ways that you can retrieve a row from a pandas dataframe object. One way is by label-based locations using the loc() function and the other way is by index-based locations using the iloc() function. Both will be explained in-depth. In the following code...
Here we get the values by the index labels. $ python series_retrieve.py 1 --- b 2 c 3 d 4 dtype: int64 --- a 1 c 3 d 4 dtype: int64 Pandas custom index The index column does not have to be numerical. We can create our own custom index. custom_index.py #!/usr/bin/python...

When we have a default numeric index, we can retrieve a row or a slice of rows by integer index. We typically do this with the Pandas iloc method. The important thing to understand is that the index values act as sort of an “address” for the rows. So you can use techniques like ...
