Pandas-concat() method

The pandas.concat() method combines two data frames by stacking them on top of each other. If one of the data frames does not contain a variable column or variable rows, observations in that data frame will be filled with NaN values.

new_concat_dataframe = pd.concat([dataframe1, dataframe2], ignore_index= “true”)

Note – If you wish for a new index starting at 0, pass the “ignore_index” argument as “true”.

Let’s understand Concat() function through coding.
