You can get the row number of the Pandas DataFrame using the df.index property. Using this property we can get the row number of a certain value
Get the First Row of Pandas using iloc[]To get first row of a given Pandas DataFrame, you can simply use the DataFrame.iloc[] property by specifying the row index as 0. Selecting the first row means selecting the index 0. So, we need to pass 0 as an index inside the iloc[] proper...
